Headings
Headings are used to organize content and should not be used to make text big or bold; also, heading tags add a margin before and after the text making them impractical for simple text formatting. Search engines use headings to index the structure and content of a web page.
Heading sizes begin with h1, being the biggest, and end with h6, being the smallest.
Examples

<body>
<h1> This is heading 1 </h1>
<h2> This is heading 2 </h2>
<h3> This is heading 3 </h3>
<h4> This is heading 4 </h4>
<h5> This is heading 5 </h5>
<h6> This is heading 6 </h6>
</body>
