What is CSS?
CSS Cascading Style Sheets are used by Joomla and WordPress to specify a website text sizes, image formatting, color, look and feel. The programming saved to a CSS file makes it easy to make site wide changes as well as control the way a site looks on different devices and phones. Most websites today rely heavily on CSS files for their design and layout.
Just like any other programming language, CSS files can be written in a number of ways, there is no hard standard. You can review the CSS files from one website to another and see little similarity in the coding.
Customizing these files takes a little skill, some cases you need to modify the code and in other cases you will need to add code.
