Why Learn CSS?

CSS works by selecting HTML elements and applying styles to them. Selectors are used to identify the elements to be styled, and declarations define the styles to be applied.

CSS has evolved over the years, and there are now several versions of the language, including CSS1, CSS2, CSS3, and CSS4. CSS3 includes many new features such as animations, gradients, and transitions that allow developers to create more sophisticated designs and effects.

CSS can be written in a separate file or embedded within HTML documents using the <style> tag. With the use of CSS preprocessors like Sass or Less, developers can write more efficient and maintainable code by using variables, and functions.
