Fading PNGs in Internet Explorer 7 and 8

Wednesday, October 7th, 2009 | Tags: , ,

One issue I recently came across was the desire to use PNGs as the background of a tooltip, and to fade the tooltip in and out of view (you can see the functionality here by hovering over 'details' or clicking on 'buy now'). In case you haven't tried this before - IE7 and IE8 generally do not react well to fading PNGs, putting a black background under the portions of the PNG which have alpha transparency - and generally making the element look less than ideal.

I ended up developing the omnitip jquery plugin because I needed something a little more robust than any of the other jquery based tooltips that I was able to find.

About Omnitip

Omnitip is a tooltip plugin (you can see it at work on the homepage). What I THINK I have added to other tooltips in terms of functionality is:

  2. Ability to send included forms through ajax components and lo...
