Add tooltip to font awesome icon
Solution 1:
The issue of adding tooltips to any HTML-Output (not only FontAwesome) is an entire book on its own. ;-)
The default way would be to use the title-attribute:
<div id="welcomeText" title="So nice to see you!">
<p>Welcome Harriet</p>
</div>
or
<i class="fa fa-cog" title="Do you like my fa-coq icon?"></i>
But since most people (including me) do not like the standard-tooltips, there are MANY tools out there which will "beautify" them and offer all sort of enhancements. My personal favourites are jBox and qtip2.
Solution 2:
Simply use title in tag like
<i class="fa fa-edit" title="Edit Mode"></i>
This will show 'Edit Mode' when hover that icon.
