When attempting to validate pages with the W3C validator, you may notice that using the ‘name’ attribute is no longer valid. That’s because the ‘name’ attribute is not supported in HTML5 and is considered obsolete. For valid markup, a newer construct is recommended: use the ‘id’ attribute instead. See the example below for the correct markup:

<!-- Incorrect Markup - 'name' attribute -->
<ul>
    <li><a href="#one">Section One</a></li>
</ul>

<h2><a name="one">Section One</a></h2>

<!-- Correct Markup - 'id' attribute -->
<ul>
    <li><a href="#one">Section One</a></li>
</ul>

<h2><a id="one">Section One</a></h2>
