My preferred answer to this is to use .gif transparency wherever possible in IE6. If you really must use .png, then you'll need an IE6 png transparency fix
Ah thanks NB. I had already found this but was sorting of hoping that there was a simpler method.
I have attached a screenshot of my latest project idea. The design is pretty reliant on alpha transparencies.
I am making a little mini-site for my business studies students. I am trying to get across the idea of a sheet of note paper out of my file. This is proving more difficult than I imagined though. Getting the text to apprear just above the lines is rather difficult. Anyway, there is a transparent plastic ruler at the bottom of the page and the menu will be in the right hand column a torn of sheet of thin (slightly transparent paper).
I think I probably just create a second style sheet for IE6 and lower that uses simpler gifs. It definately does not look quiet right but it will work, I think.
