Use Open-Source DHTML/Javascript Lightweight Tooltips For Your Website

BoxOver uses javascript / DHTML to show tooltips on a website. Implementation of the tooltips, however, requires no knowledge of DHTML or javascript. Move your mouse over the items below to see examples.

There are many tweaks which can be set to customise it to your needs.  As shown above BoxOver is set through a tag’s “title” attribute. 

Some of the salient features are:

Optimised for lowest CPU usage with lightning response times

Tested in all major browsers

Easy to set up with only a basic knowledge of HTML
