Forum:What is the best CSS code to use to resolve IE8 display issues?

It has been brought to my attention again that certain colored div boxes we are using on our main page are not displaying the proper colors for those using IE8 while those using firefox seem to have no problems.

I'm not sure if there's some sort of code that needs to be changed in our div box or if there is code that I need to add/change in our MediaWiki.css.

Seems like there was some code that needed to be added to MediaWiki.css to resolve this issue but it's been so long ago and even with searching high and low I can't seem to find or figure how to fix this.

Anyone's help would be super. I know our users who prefer to use IE would not appreciate hearing they HAVE to use a particular browser to see the pages display correct. Thanks in advance for the assistance!
