[html] Add hover text without javascript like we hover on a user's reputation

In stackoverflow, when we hover on a user's reputation we see a text. I have seen this at many places and the source code tells me that it can be done without js. And i tried and got only this-

 <div="text">hover me</div>

You're looking for tooltip

For the basic tooltip, you want:

<div title="This is my tooltip">

For a fancier javascript version, you can look into:

The above link gives you 12 options for tooltips.

The title attribute also works well with other html elements, for example a link...

<a title="hover text" ng-href="{{getUrl()}}"> download link
</a>

This can also be done in CSS, for more customisability:

.hoverable {
  position: relative;
}

.hoverable>.hoverable__tooltip {
  display: none;
}

.hoverable:hover>.hoverable__tooltip {
  display: inline;
  position: absolute;
  top: 1em;
  left: 1em;
  background: #888;
  border: 1px solid black;
}

<div class="hoverable">
  <span class="hoverable__main">Main text</span>
  <span class="hoverable__tooltip">Hover text</span>
</div>

(Obviously, styling can be improved)

Often i reach for the abbreviation html tag in this situation.

<abbr title="Hover">Text</abbr>
