CSS stands for Cascading Style Sheet. Not so illuminating as you had hoped? Well, let’s take a look if we break the definition down to the important elements:
“Style sheets have actually been around longer than the internet.”
So this is about Style Sheet – CSS. This is useful as a starting point, since we have known style sheets already at the time when the web still had to be created.
Back in the old and golden days of the world of business, style sheets were quite literally sheets (or more often, documents) that were describing, in excruciating detail, how all documents created by, or used for, a specific company should look.
A style sheet dictated exactly the typefaces that need to be used in press releases, what specific colors must be used in the masthead, where the logo must be placed, and whatever other elements you could imagine (including many you even couldn’t imagine).
If you use CSS, you can, for example, say something like ‘All of my paragraphs must be indented one inch’, and ‘All must be in 12-point double-spaced Comic Sans’, and ‘Have all lime-green backgrounds’.
