I have just a couple of questions. I was looking over at CSS ZenGarden.com and was looking at their css layout. They all use background-color:transparent;.....why? is this to cover up for older browsers? Also..what technique are they using for image replacement for the headings? I looked through the css but had a hard time figuring it out. I am a few months new with css.
Final question...if I am using png transparency should I be using a hack for older browsers and if so what is the best practice for this?
thanks for your time.
