Cascading Style Sheets (CSS) Notes

Cascading Style Sheets (CSS) are used to define the layout of Web pages.

Now, your HTML code will be used only to define the structure of your contents while the CSS will allow you to create your styles and your layout.

CSS is a very effective new way to apply styles to HTML elements.

They allow you to set any style property such as border, character type, background color, space between letters, and so on. (We will come back later on how to do this).

There are three main ways to apply CSS styles:

• In the code body (X) HTML;
• In the header of the page;
• In a style sheet completely separate from the HTML (X) code.
