CSS

Since HTML was never designed to control graphics and layout, CSS or “Cascading style sheets” came about as a way to extend the HTML specification and give web designers finer control over graphical elements.

One nice thing about using CSS is that it allows you to define design styles once (in one part of the code) and automatically apply it to the rest of the site. Another nice feature is the ability to “overwrite” global styles on a per-page basis if necessary (hence the name “cascading”).

For all intents and purposes, HTML and CSS are almost always used together.
