Add hover text without javascript like we hover on a user's reputation
Use the title
attribute, for example:
<div title="them's hoverin' words">hover me</div>
or:
<span title="them's hoverin' words">hover me</span>
The title attribute also works well with other html elements, for example a link...
<a title="hover text" ng-href="{{getUrl()}}"> download link
</a>
Often i reach for the abbreviation html tag in this situation.
<abbr title="Hover">Text</abbr>
