HTML Tags

This page lists all HTML tags that are in the HTML5 and HTML 4 specifications (including tags that are obsolete in HTML5). HTML tags are used to define the HTML elements that should appear on a web page.

HTML 4 Tags that are Obsolete in HTML5

The following tags are supported in HTML 4 but not HTML5. Therefore you should not use these if you need to be HTML5 compliant.

What Are HTML Tags?

HTML tags are the building blocks of HTML. They are the pieces of code that "tell" the web browser what elements to display on the page. Without HTML tags, you wouldn't have an HTML page. Virtually every web page contains HTML tags (even if the website also uses other programming languages).

See HTML elements for a full explanation of HTML tags and elements.
