validate IE7 IE6 Firefox 1.xx and 2.xx

[uberanimal]

I try to validate my site and test it in all versions of each browser. why is it in IE6 it displays stuff so different than IE7? Such as PNG image files.. the transparency does not come through and it turns my image a dirty grey color most times? I understand Fire Fox will display text a little different but IE6 is still being used by a lot of people and it makes some of my sites look stupid with IE6.

Fun isn't it.

Have a look at PNG Behavior (WebFX) for fix for the PNG transparency problem. Somewhere on that site is also a behaviour which fixes the :hover under IE6.

You can also use 8bit PNG as they will allow IE6 to have a transparent colour without having to do anything else, the only problem is the edges look horrid in IE6.

Also make sure you use a strict DOCTYPE as IE6 will behave a little better, but also make sure you have no characters before the DOCTYPE as otherwise IE6 will go back to quirks mode.

If you can, simply use transparent gif instead of png's as the file format is not supported by older browsers (yes IE 6 is an 'old browser )
