  3. 3. About Cascading Style Sheets Cascading Style Sheets (CSS) is a collection of formatting rules that control the appearance of content in a web page. Using CSS styles to format a page separates content from presentation. The content of your page—the HTML code—resides in the HTML file, and the CSS rules defining the presentation of the code reside in another file (an external style sheet) or in another part of the HTML document (usually the head section). Separating content from presentation also results in simpler and cleaner HTML code, which provides shorter browser loading times, and simplifies navigation for people with accessibility issues (for example, those using screen readers). CSS gives you great flexibility and control over the exact appearance of your page.
