I first tried moving to a CSS-based layout a couple of years ago to shed my use of multiply-nested tables used for positioning. While I was ripping everything apart, I added some fancier stuff. The site looked great in Firefox, Safari and even Opera. My enthusiasm was folded, spindled and mutilated when I previewed the site in Internet Explorer.
I was curious how much the user population has changed. Last July, 74% of visitors to my site used IE variants (or browsers pretending they were IE), compared to 5% FireFox. This month, it’s about 61%/20%.
Of the IE users, almost a fourth are still using pre-Windows XP systems. They will not be upgrading to Internet Explorer 7 whenever it’s released.
I’m not really sure how much I should be concerned about this least-common denominator. I’d be tempted to just abandon trying, but I’m reminded how much I hated seeing Factiva.com tell me I couldn’t use Firefox because its programmers coded to IE quirks.
