#enable the custom theme on blog settings!!

WHAT THE FUCK Y’ALL GET ALL THAT ON DESKTOP HELLO????????

😖 I miss when it was the norm. It was SO chaotic, so beautiful!!

I was going to add some things in the tags, but I please you need to know, because the one thing I remembered I HATED about it was music players! YOU COULD ADD MUSIC TO YOUR BLOG! And some evil souls would add their playlists on auto play which was a huge hilarious problem bc - story time - back then when we wanted reblog things, tumblr would open a new tab and, scrolling down the dash you wouldn't want to miss where you were, we'd open tabs and more tabs of posts to reblog, to then reblog one by one in one go and here things get tricky, because once you rebloged the post, instead of switching back to the dash, tumblr would direct you to the person's blog. Imagine you have 20 tabs open and suddenly 5 of them start playing different songs at the same time, many times on top of whatever YOU were already listening to :)

It worked as tumblr works. To be fair there were some terrible themes, people would make it nearly impossible to navigate their pages "for the aesthetic", but I miss the variety of it so much I wouldn't mind some bad designs. AND ALSO I believe users nowadays would know how to behave with this tool lol I wish Tumblr would bring it back in a way it could work with the app 😔

[official-time-loop-posts]

hiii i love ur blog but i just wanna ask if you could turn on the web version on it? i am stuck in a time loop trying to get to the earliest posts and ik theres a way that could b done on the web version. also turning on the web version lets anyone even those without tumblr to see the posts which im always tempted to send to my timeloop lover friends but can only send via screenshots HASDJFDH tyy

It should be working now! Sorry for not getting it sooner, we just had no clue how to turn it on lol

been learning a lot lately that most ppl actually do not have custom themes enabled on their blogs anymore and use essentially the mobile layout only. ppl aren't digging thru theme codes and spending hours picking the right sidebar + bg + transparent anime girl to decorate their blogs anymore...

[ Theme #11: TTYL ]

Preview + Install (Theme Garden) Live Preview + Static Preview + Code (GitHub)

A responsive, all-in-one theme that includes the option to hide the about, navigation, muses, following, and recently liked sections!

Features:

Day and night toggle button that will stay in the selected mode until it is turned off. A dark mode option is available for those who prefer a dark color scheme on their blogs instead of the default light colors. The day and night mode button will also change according to the scheme you are using.

6 sections are included in the theme (blog posts, an about me, navigation links, muses, following, and recently liked posts).

Left or right sidebar. Both layouts are responsive on multiple screens including mobile.

You can also choose icons that you like for various elements of the theme (i.e. the menu links in the sidebar) from Tabler Icons. Please refer to the theme guide linked below for more information.

Like and reblog buttons, a search bar, an updates tab, and a custom "Not Found" page.

A drop-down menu with 3 custom links.

Supports NPF posts and page links.

Options:

Instead of giving you a selection of post sizes to choose from, you can enter your desired post size (i.e. 500px or 40vw). The same applies to the sidebar.

A custom title and/or description. To activate the custom title and description options, just type anything in the text boxes "Custom Title" and "Custom Description."

You have the option to choose whether your accent colors will be a gradient or one color.

There is a selection of border styles and header styles to choose from.

Different sidebar images are optional. However, the first sidebar image that uses your header image as the default will always be visible on your blog. There is no option to hide it like the other sidebar image.

Show or hide tags on the index page.

Notes:

The search bar will be hidden automatically if you have the option to hide your blog from search results enabled.

The following and recently liked sections will only work if you're using the theme on a primary blog. It will not work with side blogs. Please also make sure you have enabled the options to share your following and liked posts in your blog settings.

For an in-depth explanation and tutorial on how to customize the theme to your liking, please refer to the theme guide! Everything you need to know will be addressed there.

[azumetapraline]

hey y'all here's a good tip: if you're an artist or want an ACTUAL blog you have THIS option right here in your blog settings

it enables your blog to have its blog url (blog.tumblr.com) in addition of your user url (tumblr.com/user)

you now have an archive! everyone can access it and search posts from any given time, tags, types, etc.

you CAN buy a domain for you

your blog is accessible for people who don't have a tumblr account

you can now customize it with pre-made themes, OR EVEN make your own theme with HTML and CSS!!

of course it therefore makes it "more public" but i think it's worth it!

Ocular — Version 3

Preview // User Guide // More Info & Install

your favorite sidebar theme just got an upgrade, babeyyy

I went to update Ocular to make it NPF post-compliant and then my hand slipped and I redesigned the whole thing lmao. here's a brief update about Ocular 3; if you're looking for a full list of changes between versions 2 and 3, click the "Read More" below)

Ocular comes with the following features:

Colors: easily change the color scheme of your sidebar and posts using any colors you want

Post sizes: 400px, 500px, 540px, 600px, 700px

Sidebar: can be on the left, right, or above the posts. pick from a list of sidebar sizes, header image heights, and avatar shapes

Fonts: 20 different fonts, sizes 13px to 18px

Background: solid, gradient, full-size image or repeating image

Links: choose either regular navigation or drop-down navigation. unlimited custom links (visit the help desk FAQ for a tutorial) and ability to rename home, ask, submit, and archive links

Endless scroll, custom ask box text, Tumblr's full-width controls and search bar, optional header, avatar, and favicon images

if you already have Ocular installed, version 3 should be coming at you as soon as the update passes the theme garden. if you installed this theme with GitHub, you'll have to re-install manually.

now let's get to the fun stuff. what's new in version 3?

wow, do I have some updates for you!

1. goodbye color schemes, hello post background and text colors

you can now directly control the color of the posts rather than relying on color schemes to do it. want your posts to be a very specific shade of navy? all yours, buddy. go wild (make sure it's readable tho)

2. hello, color schemes! wait I thought we got rid of that guy

a lot of the color schemes I made became redundant now that the new post background/text color options exist. if you were married to the old color schemes, all of them can be recreated using those options. so the new color scheme options are as follows:

"My colors" — uses the colors you picked for post background/text

"Light preset" and "dark preset" — sets the posts to white with black text, or off-black with white text

"Translucent" — uses the colors you choose for post background/text, but makes the post backgrounds semi-transparent. there are NINE different translucent color schemes, ranging from 90% (only slightly see-through) to 10% (VERY see through)

3. navigation dropdown option

you can either use the sidebar links like they were before, or you can turn them into a cute little dropdown (helpful if you have lots of links or links with long titles!) you can enable this using the "use dropdown navigation" setting. you can also customize the label for the dropdown using the "dropdown menu label" setting. for instance, the dropdown on my blog currently says "oooh you wanna click me"

4. RIP google fonts I always hated your load times

decided to stop using Google Fonts and instead I'm providing the font files directly in the code. this will help speed up load times drastically when using custom fonts, plus I don't have to use Google. win-win! there's quite a bit of coverage overlap with the old fonts, but some of them that were too similar to each other got the ax. I also added all of the system fonts as options (hit classics like Arial, Georgia, and Comic Sans MS are now available TO YOU!)

5. more layout, sizing, and spacing options

the sidebar used to be either on the center-left, center-right, or above the posts; now it can go in the top-left or top-right! you can now control the border radius on the posts and sidebar. the header height, sidebar width, and post spacing all have additional options.

6. some options have been renamed for additional clarity

"background color 1" -> "background color"

"background color 2" -> "gradient background color"

"background" -> "background style"

"font override" -> "use body font everywhere"

"title" -> "sidebar title"

"description" -> "sidebar description"

"ask box text" -> "custom HTML above ask box"

7. removed some options

you win some, you lose some. I removed the uppercase sidebar links, theme credit, and inline media spacing options, mostly for redundancy reasons or because they produced unclear results.

8. as previously stated, now NPF-compliant

Ocular was ALMOST compliant with Tumblr's new post format, but had a few tweaks that needed to be ironed out. they're now ironed.

9: now user-friendly right out of the box

I updated the default color and content options, so new users installing this theme will have a much easier time using and customizing it immediately. no more ugly ass green background!

10. and finally, new JS

I had to rewrite some of the javascript for this theme, which turned into me rewriting ALL of the javascript. doing so meant that I could eliminate dependencies on third-party JS libraries and run the whole thing on plain JS. that should improve load times!!

bonus: custom CSS can do some nifty stuff now

want to change the size of your avatar? you can do that now! just do this to your Advanced > Add custom CSS section

super helpful if you're using the Avatar shape: Uncropped setting and you need your image to be a specific size (like a pixelated GIF)

for more info, check out the Ocular user guide. thanks for reading my updates!! hope you all have a fantastic start to your 2024 ❤️

Complete-ish Guide To Settings You Might Want to Change

These instructions will be for desktop, because the settings are easier to find there. You can do the same on mobile, but it might be in different places.

Dash settings

Your dashboard is broken down into several feeds, including "Following" and "For You".

"Following" is primarily the posts of people you follow, "For You" is algorithmic.

If you just joined, "For You" is default, if you're a longtime user it's "Following". You can change this in the settings on the right

A lot of longtime users will tell you that the Following feed is where we spend most of our time. But try out all the feeds, and see what you like most.

The settings that are settings:

To start, click the settings gear under the account icon (the abstract person head).

This should take you to the General tab. Key settings:

Community Labels: By default anything NSFW is silently hidden. You can change how each subtype is handled.

Hide Additional Mature Content: If you have an iPhone disable this or it'll hide every post from you on the off-chance it contains porn.

If you're under 18 as determined by the birthdate you entered on signup, you can't change these. (If you want them on, you'll have to make a new account and lie)

Under the "Dashboard" tab, you can enable timestamps, which is mostly just nice information to have. sometimes a post is from 2010 and you can be like wow.

The next four probably have the biggest impact on your tumblr experience, so I'm gonna do a breakdown.

Best Stuff First reorders your "Following" to have popular posts at the top. Disabling it makes your feed chronological. I like it off, but up to you.

Include Stuff In Your Orbit and Based On Your Likes put various content from "For You" into "Following". Personally, I disable them to keep "Following" purely posts by people I follow, and then switch between feeds to get what I want.

Followed Tag Posts will put content from the "Your Tags" feed into your "Following" feed. Since you can go to the separate tags feed, I usually turn this off (it tends to show me a lot of duplicate posts), but up to you.

Under the "Notifications" tab you can tell Tumblr to stop sending you emails.

I'd recommend disabling all the emails--if you get a bunch of replies, Tumblr will happily send you dozens of emails, and you don't need that.

Notifications is the push-notifications in-app/in-website. The mobile app, for some reason, has a much better interface for controlling these, including the option to only get activity-notifications for mutuals. You can leave these on, or turn them off if you find the flood of notifications is distracting.

Tumblr News is a newsletter, it usually just has content from @fandom and the other staff-run recap blogs.

Conversational notifications sends you more emails.

Under the "Tumblr Labs" tab you can enable a bunch of cool beta tests.

I particularly suggest Reblog Graphs, What you Missed tab, & Popular Reblogs tab, but they're all fun to try out. A lot of these are honestly better than the For You dashboard.

For each blog you have, you can customize it's Blog Settings. Beyond things like setting an avatar or description, there's a few settings that are fun.

Custom Theme gives you your own subdomain at [blogurl].tumblr.com.

This makes your blog easier to search, and a lot of 3rd party tools depend on you enabling it. It also makes it easier to link your posts to people who don't have tumblr accounts.

You can completely customize the CSS/HTML/Javascript. you can go legitimately crazy. It's not a requirement, but if you want unlimited flexibility, go wild.

On the contrary, if you wanna run a more private blog, you can disable this and then hide your blog from search results/non-registered users.

Likes and Following are public by default. I like to turn these off so I don't have to worry about like, "what will people think if they see i'm following [...] or liking [...]". But it's also fair to keep them public if you'd like.

The other Blog Settings are important but pretty self-explanatory I think.

Finally, there's some useful tools I like:

XKit Rewritten - A bunch of scripts (like RES for Reddit). The one I really like is "mutual checker", which shows at a glance which blogs you are in mutuals with. Which is such a good feature it's included in the mobile apps by default i think.

siikr.tumblr.com - Tumblr search is bad, and google's indexing of tumblr blogs is worse. Siikr will find any post you've made on your blog. Because disk space is limited, only use it to search your blog, and if you're tech savvy consider running a local copy from source.

[wip]

I wish there was an option to simply view all reblogs, rather than with tags or without separately, or even all notes- reblogs with and without tags and comments, and likes, all together and chronological. It's nice that we can filter!! But it would also be cool if we could have the unfiltered option as one of the choices.

Also wrt to notes, it would be nice, when someone reblogs a post and adds an image, if there were some indication of this having happened or way of knowing about this in the activity feed; currently this is not the case, at least on desktop

Answer: Hi, @b-a-n-d-e-r!

All good questions. You can actually still see the single feed of notes on the blog network if the blog has the custom theme option enabled in its settings. We used to have this in Tumblr itself, but honestly, it gets very overwhelming very quickly, and it becomes difficult to find the content you want, hence the separation now.

As for the second point: we agree! As it happens, we are still working on improving activity items and updating the reblog one to indicate when a reblog has just added an image without text is on our to-do list. We will have updates for you here, and hopefully before too long. Keep an eye out here and at @changes.

Thanks for getting in touch. Keep the questions coming, folks.

Page 04: POKÉDEX 98 

Preview  | Code

An about page that is also a Pokédex mini web application, based on the Pokémon Yellow interface design. Why? Because is having a Pokédex in your blog is cool! (｡◕‿‿◕｡)

Read the customization guide here.

Features:

A full functional Pokédex. You can search any of the current 1000+ existing pokémon. 

Set your dream team easily.

Change the language of the Pokédex.

About section.

Tags/Links section.

Extra section that can be used for more information, terms of use, FAQ, etc.

Toggle Light/Dark Mode and customize it, too.

Add background music and switch on/off.

Select between ultra retro or modern sprites for your team.

Responsive on mobile.

More info:

This page retrieves all the pokémon information through the services of the Poke API. The Poke API is a full RESTful API linked to an extensive database detailing everything about the Pokémon main game series. This means this page does not have coded any information of the pokémon, instead every time you search a pokémon the app connects to the API and gets the information back.

Notes:

This is the first version of the page, but in the future I will add more functionalities! Recommendations are always welcome.

The Pokémon nformation is dependant of the Poke API database, so if there is some information missing or wrong the Pokédex page can’t control that.

Make sure you have Javascript enabled on your blog.

Credits on code.

Inspiration came from Pokémon first generation games and also the page was inspired by @nyctothemes beautiful first generations themes! Check them out!

Please reblog/like if using! :3

Im asking u this cos I don't have enough followers to get my post noticed if I post it on my blog lol, but do you know why the fuck tumblr won't let me make a sideblog that has the existence of [url].tumblr.com and the new side blog i just made only exists as tumblr.com/[url]???

You need to go into the settings of the sideblog and turn on the option for "use custom theme" - the default now is the tumblr.com/url, enabling a custom theme gives you url.tumblr.com. You don't have to make changes to the theme or anything, just enable it.

[6raveyardbat]

I love your tumblr theme esp the red sparkles that move with the mouse and how your info is on the side. I want to do something similar to it but I could only manage to change my accent + bg colour before everything got too confusing (；´д｀）ゞ┭┮﹏┭┮ can you give advice on how you did yours?

THANK UUUU im glad u like it !! :3 its p easy honestly just enable 'Custom Theme' in the Blog Settings then 'Edit theme'

then itll take u to like smth like this (itll be blank for u or just plain bg color and whatnot)

go here and click on 'Browse Themes' and just scroll to what you want! for me, i chose 'Stereo by nonspace'

BUTTTT!! most of the customization is in this section so just have fun with it;

for the cursor sparkle things, i followed this thing; its just copy pasting a whole lotta code lol

🌟 New

We’ve made some updates to our documentation on how to make custom themes for blogs, specifically about how to handle Neue Post Format (NPF) posts versus “legacy” format posts.

🛠 Fixed

Fixed a previously-ongoing issue on all platforms that was causing some reblog activity items to be mysteriously missing from the activity feed. They’re all back now!

On iOS, we fixed a bug that was causing the Tumblr Supporter badge announcement banner at the bottom of the screen to nag you a bit too often.

We’re fixing up some visual glitches on web that can happen when initially loading feeds, which were causing feeds to jitter into and out of existence briefly.

Fixed a bug that was preventing folks from adding more than one link to custom pages to their blog on the web.

Fixed an issue that was causing some feeds to break because someone… somewhere… figured out a way to include more than the maximum number of poll options in a post. And zero options in a poll.

🚧 Ongoing

In the latest version of the iOS app, some folks are seeing a greyed out clock icon (🕒) on posts, next to the reblog button. This is the Fast Queue experiment from Tumblr Labs settings, but it’s not supposed to be there for everyone like it is now. We’re working to remove it for folks who don’t have the experiment enabled.

🌱 Upcoming

Stay tuned to the @engineering blog for an exciting peek into our latest hackathon, publishing soon!

Experiencing an issue? File a Support Request and we’ll get back to you as soon as we can!

[cacodaemonia]

I was telling some friends about how useful the archive feature on Tumblr is, so I went to find an old post I'd reblogged and added to a while back. I wanted to update a couple of things in my reblog of it, but I kept getting an error message about the original post's reblog settings, so I then discovered that reblogs have been turned off. :( Anyway, here's the OP if you want to check it out, and my addition, which I hope is useful to some folks:

I highly recommend using your Tumblr archive on desktop (or mobile browsers)! Without it, Tumblr is kind of a black hole that eats anything you share, and I would never be able to find things I've posted or reblogged.

For folks who don't know how tags work in your blog's archive, you can search for any tag you've ever used and the archive will show you all those posts and reblogs in a handy grid format. For example, if I want to see the fics I've recommended, broken down by month, I go to (remove the spaces after the periods):

cacodaemonia. tumblr. com/archive/tagged/fic rec

Once the page loads, the url will read 'fic%20rec' at the end, but you can enter tags normally when you're searching for them. In other words, use spaces and don't worry about the %20.

You can also use the archive with other people's blogs, assuming they have 'enable custom theme' toggled on under blog settings (there's some disagreement about this in the OP linked above - possibly, you can see anyone's archive if they have certain visibility settings toggled? idk). So if someone you follow uses consistent tags for their art, fics, gifs, meta, etc., you can use the same url format above—just replace my username with theirs, and 'fic recs' with whatever tags you want to search for.

This probably seems super basic for a lot of Tumblr users, but it's something I figured out on my own after ages of being frustrated with the site's 'search function,' so hopefully this will be helpful for people who don't know about the feature.

[ryanyflags]

On archiving lgbt/mogai content

Everyone is of course free to what they want, but during my time searching for terms, and archiving their sources, I have a couple of ideas that I think would be helpful.

Make a copy on sites specifically for archiving

Archiving posts using reblogs is great and all, but I think it's much better to make a copy of them on actual archiving websites, such as Wayback Machine and Archive Today (for Archive Today specifically, there are a bunch of different urls, such as archive.ph, archive.is, archive.li, etc. but don't be confused, as far as I'm aware, they are all the same site).

Tumblr blogs can and do get deleted (not to mention your information shouldn't be stuck with one social media company, if they ever go down you don't want your queer terms/history disappearing with it), so I really think it's much more reliable to make your own copies.

On Wayback Machine vs Archive Today, they both have their benefits and downsides. Mainly Wayback doesn't archive images, only links to them, so in the case the original source gets the deleted, the images will be gone too. Archive Today does archive images, but it kind of just.. exists. Unlike Wayback, which is an actual non profit organization in California. So I'm slightly concerned about the long term stability.

I think it's best to just archive it on both sites, in addition to saving the original link + reblogs, perhaps even a self made copy + offline copy if you are really concerned. (If you do go the last route, please chose a common, open, file format. Don't use a app/service that doesn't let you easily export everything to something like a .txt file, or uses some odd propriety format that isn't easily compatible/viewable in other programs.)

Enable the website version of your blog, don't only use @ version

If you post flags/terms on Tumblr, please enable the exampleusername.tumblr.com version of your blog, instead of only using the @ exampleusername version.

E.g. @ryanyflags is the @ version of my blog, and ryanyflags.tumblr.com is the website version.

The problem is the @ / tumblr view version isn't compatible with archiving sites. When trying to archive posts in Tumblr view, Archive Today would get stuck trying to download the website, and both would end up with "please login to view" and the actual post isn't saved. I have been able to get around it by reblogging to my blog, which has a website version, and archiving that instead. But I think it would be better to be able to archive the post on the original blog.

You can activate it by enabling "custom theme" in your blog's settings. You don't even have to actually customise the appearance, it only matters that the website exists. (Image of the settings below)

Example of a post in "tumblr view" as I call it, and "website view".

Don't change your username when you stop using a blog

For example, when deciding to not use/post to a blog anymore (which is perfectly understandable), some will change their username from "example-name" to "example-name-archive", or "-inactive", and other such variations.

All the un-archived links to all that blog's posts break. And it messes anything linking to it in general, I'd say.

Unless you want to delete any references(links) to your posts, or make it harder for people to find your archived content, just don't do this. I personally don't understand why changing the title of a blog to something like "inactive" wouldn't be sufficient, or what the point of it is. But it's up to other people to do what they want.

(I wouldn't mind if someone just wanted to change their username, I just don't get appending inactive to it.)

Use the archiving sites to save content under "read more"

This is an issue that has been brought to my attention before. When the original post gets deleted, the content under "read more" (or "under the cut") of the reblog disappears.

I've tested it out myself using Archive Today and Wayback, see here and here. It's just some text with a read more in the middle.

If you check, the original post has been deleted, actually, the whole testing blog is gone. But the archives have kept the content under read more.

So instead of copy and pasting read-more content in reblogs, I think just using Archive Today and Wayback is way easier.

(Also, I just realised I didn't test this out with Tumblr view, though with the above issues I'm not sure it would have worked at all. If anyone want to test it out themselves, well it's free.)

People say things on the internet are forever, and maybe some viral things are, but I don't think that's really the case. Cool stuff can disappear all the time, and relying on some companies just doesn't seem reliable to me. Best make copies on separate archiving sites, and make your own offline ones.

My focus is really just on flags. I have a whole file folder filled with pngs of all sorts of flags (I think 4000+ ?). I sort them however I want, I can look at them on any device, regardless of operating system, I can make as many copies as I want and transfer them to new devices, I can easily use them in any program if I want (like to reference to make other flags). It's great. I don't have to worry about any individual or company deleting it or anything of that sort. It's just my own copy. For everyone else that cares about terms, I imagine saving the pngs and definitions in markdown files would work well enough.

This is nothing but my opinion at this point, but I really think making your own copies (whether offline or on archiving sites) of stuff on the internet is the way to go.
