Headings are useful elements to define various levels of headers on the page.

Defining larger headings expresses the importance of the content below it. H6 is the smallest – H1 is the largest.

● Example (Largest to Smallest) :

<h1>header 1</h1>
<h2>header 2</h2>
<h3>header 3</h3>
<h4>header 4</h4>
<h5>header 5</h5>
<h6>header 6</h6>

Headings can be aligned by using “align” attribute in the tag:

<h4 align="left">header 4</h4>
