The text-indent property can be applied to Block-level elements (P, H1, etc.) to define the amount of indentation that the first line of the element should receive. The value must be a length or a percentage; percentages refer to the parent element's width. A common use of text-indent would be to indent a paragraph:

<style>
li.small { text-indent: 5em }
li.medium { text-indent: 10em }
li.large { text-indent: 15em }
</style>
<ul>
<li>This text is displayed normally</li>
<li class="small">This text is displayed with a small indent</li>
<li class="medium">This text is displayed with a medium indent</li>
<li class="large">This text is displayed with a large indent</li>
<ul>

Would be displayed on your screen like this:
