Cool trick here — Collylogic: Scroll Fade
Using IE or some antiquated crap? You see a big nasty block where the PNG is. If I cared about you, I’d hide the fade class from you by giving you your own stylesheet.
What really grabbed my attention is that when I did this same special effect several years ago for just IE, I didn’t need a PNG (so no separate download slowing it down & further loading the server). I just used IE‘s CSS Visual Filters, which I wish other browsers would support.
It could be fairly trivial to combine the two techniques for a cross-browser method. Or heck, just fix IE‘s PNG rendering with another CSS Visual Filter.
