I was looking at some code on a website and I saw the following code for a link:
<a href="#" _mce_href="#">Link Text</a>
What is _mce_href
?
Is there a purpose for it?
That's not a valid HTML attribute, it was kind of bug in older versions of Tiny MCE editor, though, using data-
prefix before that attribute can make that custom attribute valid as of HTML5.
