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>
title
たとえば 、次の属性を使用します。
<div title="them's hoverin' words">hover me</div>
また:
<span title="them's hoverin' words">hover me</span>
title 属性は、リンクなどの他の html 要素でもうまく機能します。
<a title="hover text" ng-href="{{getUrl()}}"> download link
</a>
