Question

Hello friends
I am new user here
Anyone able to describe Mata tags for me.. I want to know what is Mata tags and what should including in this tags and how it's works...

Answer 1

A tag inside another tag is a meta tag.
For example:

<nav id='wrap'>
<div id='article'>
</div>
</nav>

The 'div' tag is inside the 'nav' tag . So, the div tag is meta tag here.
