CSS can be used to set the style parameters of your entire website. With CSS, you can control the look of your website’s:

• Font types
• Font and element colors
• Padding
• Margins
• Element positioning
• And much more.

The advantage of CSS is that it allows you to set the formatting of your site without affecting the site’s underlying structure. By separating the layout and formatting properties of your website from its underlying logical structure, you can make cosmetic changes to your site without running the risk of altering the integrity of your site’s data by accident.
