To the point: This entry introduces a new CSS filter that can be used to import a separate style sheet for IE5/Mac, named the IE5/Mac Band Pass Filter.
Back Story
Ideally, I try to avoid the use of hacks in CSS files, if at all possible. Sadly, the continued discrepancies in the way browsers interpret CSS specifications (and then implement them) still require the use of more hacks than I’d like to see in my style sheets. I would prefer not to use any hacks or filters, but sometimes, they’re a necessary evil. Fortunately, hacks, workarounds, and filters can be used with discretion to ensure as much cross-browser design consistency as possible. continued
