A

Heading elements are block level elements that can be used directly as a sub-element in the body element. You can use heading elements to specify heading in different sizes. Here are basic rules about heading elements:

  • There are 6 heading elements, named as "h1", "h2", "h3", "h4", "h5", and "h6".
  • Heading elements are mixed content elements.
  • Heading elements can have empty contents.
  • Heading elements can have PCDATA as contents.
  • Heading elements can have in-line elements as contents.
  • Heading elements can not have block elements as contents.
  • Heading elements are block elements. They can not be used as in-line elements.
  • Browsers display different heading elements with different font sizes. "h1" element will be displayed with a larger font size, and "h6" with smaller font size.

Here is a good example of heading elements:

<?xml version="1.0" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
 <head>
  <title>Levels of Headings</title>
 </head>
 <body>
  <h1>XHTML Recipes by FYIcenter.com</h1>

  <h3>Recipe #101 - Creating Doducment Title</h3>
  <p>Bla bla...</p>
  <h2>Menu for the BODY</h2>
