Style sheets or CSS (cascading style sheets) are used to be able to control the look of the content on your pages.
You can use external style sheets to define color, fonts, backgrounds etc in a page, then link many pages to that
same style sheet. This allows you to make changes in one place, and have that one place effect all pages linked to
the style sheet.
Styles in a document can be accessed using scripting to make many different effects. Most style properties can used in scripting
using the property names after aquiring a reference to the element. Usually removing the hyphen, and capitalizing the letter
following the hyphen. In the below example we show you the syntax of this:
