The Acid Test Challenge

| March 17, 2005 | Category: Cascading Style

By now you’ve probably read this elsewhere — Opera have challenged MS to a CSS comformance duel. The old acid test was first passed by IE mac, yet somehow I have my doubts that IE will take the title this time ‘round.

To contribute to the challenge, I’ve thrown together a quick acid test of my own, one which combines a few challenges for IE; including

  • Fixed positioning (elements and backgrounds)
  • 24-bit PNG
  • Sizing/positioning an element using left:; right:; top:; bottom:;
  • Styling of the html element (which IE6 already does… sort of ;-))
  • XHTML 1.1 served with its correct mime-type (insert evil laugh here!)

I’m very tempted to make up a second acid test based solely around the multitude of bugs associated with IE’s hasLayout property, but really, what’s the point? :-|

    I’m tempted to think IE 7 won’t fix most of the CSS 2 bugs in IE 6, yet alone CSS 3, which Safari and Mozila partly support…

    Actually, IE handles 24-bit PNG already… I think you mean 32-bit PNG (with alpha transparency).

    Yow! My copy of IE (6.0/pc) won’t even *open* that acid test of yours! I must have let it read too much Tom Wolfe and scared it silly. Poor thing…

    It will be interesting to see how IE7 works with the Web. Since MSN switched to a CSS-based layout, I’d think Microsoft has a bit more at stake in making their browser render pages according to Web standards (read as: correctly). Now, if they can just get someone to redesign MSN to render according to any sense of style! What a piece…

    i tried the acid 2 test, with firefox, IE 6 and Opera 8 beta and the browsers all kinda failed :(

    Firefox was of course the closet to rendering the image, but opera and IE were miles off.

    Lets hope this test pushes all the major browsre manufactures to enhance their CSS support!!
