CSS+JS implementation of an excellent hyperlink mouse hover hint

css|js| link | Mouse hyperlink, the general practice is to give a title property, so that the user's mouse hover over the hyperlink, it will show the title of the content. But are you tired of the same mouse hover effect?
Of course, there are also very cool code, but only across the browser Kungfu is not enough, hehe. I met a good css, in IE and Firefox browsing the same effect.
The actual effect you can refer to: Campus Recruitment catch ( http://www.xyzp.net/）、 http://www.xyzp.net/index.html

The code is as follows:
