HTML headings are used to define titles and subtitles on a webpage. They help organize content so that it is easy to read and understand.

HTML provides heading tags from <h1> to <h6>

• <h1> defines the most important and largest heading
• <h6> defines the least important and smallest heading

As the number increases from 1 to 6, the importance and size of the heading decrease.

Headings are also important for structuring content properly and making webpages easier to understand for both users and browsers.
