So, HTML structures web pages with elements like headers, paragraphs and lists while CSS contains the style information for those structures. While neither HTML or CSS is more complex than the other in terms of syntax, a major difference is that HTML can contain CSS within its code and files, but CSS cannot contain HTML. Both HTML and CSS are mutually containing, however, meaning CSS and HTML share tag names with each other. One of the goals of CSS is to allow users greater control over presentation. Someone who finds red italic headings difficult to read may apply a different style sheet. Browser extensions like Stylish and Stylus have been created to facilitate the management of such user style sheets.

Content is written in HTML, short for HyperText Markup Language. In short, HTML is responsible for defining the content and structure of a web page. Pseudo-classes are used in CSS selectors to permit formatting based on information that is not contained in the document tree. Classes and IDs are case-sensitive, start with letters, and can include alphanumeric characters, hyphens, and underscores. In CSS, selectors declare which part of the markup a style applies to by matching tags and attributes in the markup itself.

CSS is not technically a necessity, but you probably wouldn’t want to look at a web page that features only HTML elements as it would look completely bare-boned.

CSS can be used for very basic document text styling — for example, for changing the color and size of headings and links. It can be used to create a layout — for example, turning a single column of text into a layout with a main content area and a sidebar for related information. Have a look at the links in this paragraph for specific examples. You might be wondering how this CSS code is actually applied to HTML content, though.

Consult the information in that table to check if the property can be used on your website. For an example, see the browser compatibility table for the CSS font-family property.
