Introducción a CSS: Estilizando la Web

Introducción

CSS (Cascading Style Sheets) es el lenguaje que se utiliza para describir la presentación de un documento escrito en HTML o XML. Mientras que HTML estructura el contenido de la web, CSS se encarga de darle estilo, desde la disposición de los elementos hasta los colores y las fuentes. Si estás empezando en el mundo del desarrollo web, aprender CSS es esencial para crear sitios atractivos y funcionales. En este blog, te proporcionaré una introducción a CSS, cubriendo sus conceptos básicos y algunas prácticas recomendadas para que puedas comenzar a diseñar páginas web impresionantes.

1. ¿Qué es CSS?

CSS es un lenguaje de hojas de estilo que permite definir cómo se muestran los elementos de un documento HTML en la pantalla, en papel o en otros medios. Gracias a CSS, puedes separar la estructura de un sitio web de su presentación, lo que facilita el mantenimiento y la escalabilidad del diseño.

a) Características Principales de CSS:

Selección de Elementos: CSS te permite seleccionar y aplicar estilos a elementos HTML específicos o a grupos de elementos.

Diseño Responsivo: CSS facilita la creación de diseños que se adaptan a diferentes tamaños de pantalla, desde dispositivos móviles hasta monitores de escritorio.

Control de Estilos Visuales: Con CSS, puedes controlar el color, el tamaño, la fuente, el espacio entre elementos, y mucho más.

2. Cómo Empezar con CSS

Para comenzar a usar CSS, puedes incluir las reglas de estilo directamente en un archivo HTML o en un archivo CSS separado. A continuación te muestro cómo hacerlo:

a) CSS en Línea:

Puedes aplicar estilos directamente en los elementos HTML utilizando el atributo style.

b) CSS Interno:

Puedes definir un bloque de CSS dentro de la etiqueta <style> en el <head> de tu documento HTML.

c) CSS Externo:

La mejor práctica es usar un archivo CSS separado para mantener el estilo y el contenido por separado.

Contenido de styles.css:

3. Conceptos Básicos de CSS

CSS se basa en reglas que constan de selectores y declaraciones. A continuación te explico los conceptos más importantes:

a) Selectores:

Los selectores indican qué elementos HTML deben ser estilizados.

Selector de Elemento:

Selector de Clase:

Selector de ID:

b) Propiedades y Valores:

Las propiedades son aspectos específicos del estilo que se aplican a los elementos, como color, fuente, y margen.

Propiedad color: Cambia el color del texto.

Propiedad font-size: Cambia el tamaño de la fuente.

Propiedad margin: Define el espacio exterior alrededor de un elemento.

c) Especificidad y Herencia:

La especificidad determina qué reglas CSS se aplican cuando hay conflictos, y la herencia permite que ciertos estilos se transmitan a los elementos hijos.

Especificidad:

Herencia:

4. Diseño de Páginas Web con CSS

CSS permite controlar el diseño y la disposición de los elementos en una página web, facilitando la creación de sitios visualmente atractivos y organizados.

a) Modelos de Caja (Box Model):

Cada elemento en CSS se representa como una caja que comprende márgenes, bordes, rellenos y el contenido.

b) Layouts (Diseños):

CSS proporciona varias técnicas para organizar elementos en una página, incluyendo Flexbox y Grid.

Flexbox:

Grid Layout:

c) Media Queries y Diseño Responsivo:

Las media queries permiten que los diseños se adapten a diferentes tamaños de pantalla, lo que es fundamental para crear sitios web responsivos.

5. Recursos para Aprender Más CSS

Documentación Oficial:

MDN Web Docs: Una guía completa que cubre todo lo que necesitas saber sobre CSS.

Tutoriales en Línea:

CSS-Tricks: Un sitio repleto de tutoriales, ejemplos y trucos para mejorar tu uso de CSS.

W3Schools: Un recurso fácil de seguir para aprender los fundamentos de CSS con ejemplos prácticos.

Libros Recomendados:

“CSS: The Definitive Guide” de Eric A. Meyer: Un recurso profundo para desarrolladores que quieren dominar CSS.

“CSS Secrets” de Lea Verou: Este libro revela técnicas avanzadas para crear efectos y diseños sorprendentes con CSS.

Conclusión

CSS es una herramienta poderosa para cualquier desarrollador web. Desde controlar la apariencia básica de los elementos hasta diseñar sitios complejos y responsivos, el dominio de CSS te permitirá crear experiencias web atractivas y profesionales. Comienza practicando con los conceptos básicos, y poco a poco, profundiza en las técnicas más avanzadas para llevar tus diseños al siguiente nivel.

Debugging Your Kivy App with MD Python Designer: Common Pitfalls and Solutions

The creation of applications with the Kivy UI Designer is, indeed, an exciting journey. One can create truly fantastic, cross-platform interfaces without any problems. Even the best designs, however, may become a problem when one starts coding. So, effective debugging of your Kivy app is a critical step to achieving a good user experience. In this post, we will go over common pitfalls developers encounter while using the Kivy UI Designer and how to resolve them.

The Kivy Event System Kivy applications suffer mainly from a lack of understanding of the Kivy event system. Kivy is an event-driven architecture where several functions are exposed to user actions or system events.

Solution: Make sure you understand how the event flow works in Kivy. Print statements or logging can show you when and where events are triggered in your application, so you can trace the problem back to its source and easily identify and solve it.

Widget Sizing and Positioning Another problem developers often encounter is that the widgets are not sized or placed correctly. Sometimes, the widgets overlap or do not appear as intended because of the wrong layout properties.

Solution: Use Kivy's layout classes, like BoxLayout, GridLayout, etc., to control the placement of widgets dynamically. These classes maintain the integrity of the layout regardless of screen size and orientation. You can preview these layouts directly in the Kivy UI Designer, making it easier to change widget properties.

Resource Management Applications that support images or fonts will hang or crash if resource management is missing. Often, programmers forget to include the needed files as part of a package and errors are triggered at runtime.

Solution: Check your project setting every time when you go back to Kivy UI Designer, referenced, and included every necessary resource when you go through with creating your APK, used relative paths and avoid using an absolute path that makes it run whichever the environment it is placed into.

Wrong Data Validation The most common mistake is binding events to the wrong functions. This might lead to unexpected behavior, like not being able to use some buttons or triggering something inappropriate.

Solution: Check your event bindings with Kivy UI Designer. Using the properties panel, it's easy to see what functions are bound to the events. Ensure each button or interactive element is properly assigned to its respective callback function.

Debugging Code with Integrated Tools Kivy UI Designer has integrated debugging tools that are going to be a savior when it comes to debugging; however, most of the developers forget about them and use only manual debugging techniques.

Solution: Use the Kivy UI Designer's internal debugger. This will allow you to set breakpoints and debug variables, and step line by line through your code so you can clearly observe how the application is going to behave at run-time. Learning how to leverage these features will sharply diminish debugging time.

Layouts and responsiveness Since Kivy is designed for various devices, it may be hard to ensure that your app is responsive. A layout that works fine on one device does not necessarily display correctly on another.

Solution: Test your app on different devices and orientations. The Kivy UI Designer will let you simulate different screen sizes, which will help identify layout issues. In general, always use a flexible design approach and make use of relative sizes, such as percentages, when designing widgets.

Documentation and Community Documentation and community forums will be Kivy's most valuable assets. In a way, one could say that most of the time, it's not very different when the problem developers face often looks very familiar, and the solution is documented by others.

Solution: The Kivy documentation is what needs to be consulted if unclear issues arise to find out how a specific function or feature works. In some cases, discussion of your debugging problem in the community on Stack Overflow or Kivy Google Group will get you through the situation. Conclusion Kivy application debugging is pretty daunting. Yet, once you are cognizant of common traps and leverage the Kivy UI Designer features, things could become quite smooth and relatively easy. Once you find a way to remain organized with all the tools and resources accessible to you and your community, then your process is easier, and the end result - polished applications on the part of your end users - will not seem as challenging. Keep in mind that every bug might provide you with an opportunity for learning and improving in regards to coding skills. Stop running away from debugging procedures; push your projects along!

5-2-24: Day 76

Day 76 consisted of

Accessibility review

Challenge 1: The check out view in Cupcake Corner uses an image and loading spinner that don’t add anything to the UI, so find a way to make the screenreader not read them out:

Challenge 2: Fix the list rows in iExpense so they read out the name and value in one single VoiceOver label, and their type in a hint:

Challenge 3: Do a full accessibility review of Moonshot—what changes do you need to make so that it’s fully accessible?

I could picture this in my head and decided not to write the code, but the changes would include: using .accessibilityElement(children: .combine), .accessibilityRemoveTraits(.isImage), and .accessibilityAddTraits(.isButton) on each of the mission buttons (images) that navigate to a detail view, as well as on a few of the Text views and stacks in ContentView, GridLayout, ListLayout, MissionView, and AstronautView. I would also create a constant to store the labels for each of the crew members’ names and mission badges to be read correctly by VoiceOver using .accessibilityLabel(), instead of reading the image file names which are currently only a crew members’ last name and "apollo" with the number beside it.

Day 76 quote: "Accessible design is good design—it benefits people who don’t have disabilities as well as people who do." - Steve Ballmer

android has so many fucked-up little elements it’s ridiculous. it starts off normal (you want to make a set of linear visual elements? oh use LinearLayout! you want to make a grid of stuff? use GridLayout!) but then it gets to be so specific like why does some of this stuff even exist. if you want to make a page-style UI, you can’t just make a set of views and a swipe listener and swipe between them, you have to use a ViewPager with a PagerAdapter. if you want to make a list of stuff, you can use ListView (normal) or you can use RecyclerView and make a RecyclerViewAdapter and then a ViewHolder to go along with it (why are there three different things? because android). im going to lose my fuckign mind

. Location | Datong, Shanxi province, China The original city wall in Datong was built in 1372. It was 14 meters high, had 4 main gates, 4 turrets and 46 watch towers. The ancient city used to be one of the nine military towns along the Great Wall of China. The industrialisation however damaged or destroyed some of its old buildings and thus its history. If planners and developers in Datong had been more sensitive and respected its history, then Datong would perhaps still be as beautiful today. . Now, however, the municipality has initiated a restoration plan which has been going on for more several years. The plan has the intention of restoring the city walls similar to how it looked like in its glorious years. Moreover, Datong’s municipal government have started demolishing newer buildings in favor of replicating older ones. The city will thus shift its focus towards a historical tourism. . The formerly disordered urban planning in the city was an important fight for an upcoming Chinese historical revivalist movement. Supporters of urban regeneration have praised the movement for protecting the city’s traditional culture, giving the city a face-lift, and improving the environment and air quality. Critics, however, say that the movement is a waste of money and labor because they claim the restored buildings don’t live up to their former glory, and that the municipal government has failed to properly compensate and relocate displaced residents. . #datong #shanxiprovince #china #worldurbanplanning #urbanplanning #cityplanning #architecture #restoration #urbandesign #gridlayout #cityscape #citywalls #도시 #도시계획 #aerial #aerialview #drone #houses #大同 #다퉁 #중국 #city (at Datong)

Programming Languages VS Scripting Languages --------------------------------------- --------------------------------------- Most programming languages require the code to be compiled into machine code before it can be executed. --------------------------------------- Scripting languages are interpreted and executed line by line. Many programming languages have strict typing, where variables must be declared with a speciic data type. --------------------------------------- Scripting languages often have dynamic typing, where the data type of a variable is determined at runtime. Programming languages often require manual memory management. --------------------------------------- Scripting languages have automatic memory management. Due to their compiled nature, programming languages can be faster than scripting languages. --------------------------------------- Scripting languages are usually easier to develop with and faster to write. 📌Just like Flexbox containers we have Grid containers but have different container properties. ⇒ Simplifying GRID layout for you in this post ♥️ Hit like, if you found it useful!! 🔖 Save it for the future 📤 Share it with your connections 💭 Comment your thoughts 🚀 Follow @rehman_coding for more daily web development tips and tricks. #content #webdev #coding #css #webdevelopment #comment #contentcreation #devcontent #frontend #frontenddevelopment #HTML #Javascript #react #codewithcoffee #grid #codewithcoffeeindia #future #share #connections #like #css3 #csstip #html #htmltip #csslayout #cssgrid #grid #cssgrid #gridlayout #terminology https://www.instagram.com/p/CoiU3fRAPrz/?igshid=NGJjMDIxMWI=
