CSS is a very vast topic seems to be easy at first, but it becomes a pain in a head when you want to master it not for lack of tutorials but for lack of path or full curriculum to mastering it, here I am going to show you how to master CSS by following a curriculum contain very comprehensive resources from the internet, and sure it will be free.


What is CSS?

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language like HTML. CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript. CSS is designed to enable the separation of presentation and content, including layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file and reduce complexity and repetition in the structural content.

How this curriculum work?

In each section you can find πŸ“– Contents and πŸ“š Resources, in contents I show to you what topics included in this section then in resources sections I list some of the big and most comprehensive ( articles, videos or courses ) resources covering this topic.
But before you start you need to learn the basics of HTML & CSS then follow the Curriculum to master CSS.


HTML&CSS Basics


πŸ“† Curriculum

CSS can be categorized into four main categories:

  1. Syntax: includes selectors, properties, values, and specificity.
  2. Visual: includes styling content, responsive web design, and animations.

A CSS rule-set consists of a selector and a declaration block:

The selector points to the HTML element you want to style.
The declaration block contains one or more declarations separated by semicolons.
Each declaration includes a CSS property name and a value, separated by a colon.
A CSS declaration always ends with a semicolon, and declaration blocks are surrounded by curly braces. (Source: w3schools)

CSS Specificity

At some point in your work, you'll find yourself in a situation where multiple CSS rules will have selectors matching the same element. In such cases, which CSS rule "wins", and ends up being the one that is finally applied to the element? This is controlled by a mechanism called the Cascade, One of the most important concepts to master as you start to dig into more advanced concepts is specificity, Specificity is basically a measure of how specific a selector is. (Source: MDN)

The CSS box model is the foundation of layout on the Web β€” each element is represented as a rectangular box, with the box's content, padding, border, and margin built up around one another like the layers of an onion. As a browser renders a web page layout, it works out what styles are applied to the content of each box, how big the surrounding onion layers are, and where the boxes sit in relation to one another. Before understanding how to create CSS layouts, you need to understand the box model. (source: MDN)

πŸ“– Contents

  • Content (images, text …etc).
  • Padding (Transparent area around the content, inside of the box).
