Cascading Style Sheets (CSS) are a series of formatting rules that control the appearance of Web page content. When you use CSS to format page formats, content and presentation are separated from each other.

The term "cascade" refers to the ability to apply multiple styles to the same element or Web page. For example, you can create a CSS rule to apply a color, create another rule to apply the margins, and then apply both to the same text on a page.
