0Close All HTML Elements
In HTML5, you don't have to close all elements (for example the <p> element).
We recommend closing all HTML elements.
Bad:
<section>
<p>This is a paragraph.
<p>This is a paragraph.
</section>
<p>This is a paragraph.
<p>This is a paragraph.
</section>
Good:
<section>
<p>This is a paragraph.</p>
<p>This is a paragraph.</p>
</section>
<p>This is a paragraph.</p>
<p>This is a paragraph.</p>
</section>
Close Empty HTML Elements
In HTML5, it is optional to close empty elements.
Allowed:
<meta charset="utf-8">
Also Allowed:
<meta charset="utf-8" />
However, the closing slash (/) is REQUIRED in XHTML and XML.
If you expect XML software to access your page, it is a good idea to keep the closing slash!
