CSS is a very important thing on the internet, so I decided on doing a little explaining. It stands for Cascading Style Sheets, and it’s a style sheet language that basically defines the look and form of the web, or a particular website. It’s used, so the text and the layout can be separated. With CSS we can define the color, fonts of a website on multiple pages.
So very simply describing what CSS is, I could say that it is a style, the style of a particular website, regarding colors, fonts, etc., and it controls these over the whole of the website.
But I’m gonna let an infographic speak instead of me.
