Well, Ian's world.Media queries and performance in Acid3 (and an error on my part)- April 22, 2008 David Baron of Mozilla discovered some errors in the Acid3 test. It turns out that the Media Queries draft changed between 2002 and 2007, and I was testing things as they stood in the 2002 version of the specification! This has now been fixed. He also found a logic error that I'd made, which I have also fixed. I'm really glad to see the Acid3 test being reviewed so carefully. With something so complex it's always possible that there are more errors, though, so if you find any more please let me.http://ln.hixie.ch/?start=1208832405&count=1 The performance aspect of Acid3 on embedded devices- April 3, 2008 In my last post I discussed what "the animation has to be smooth" means for Web browsers on computers. Of course, embedded devices also have Web browsers, and Acid3 is as important for those as it is for a regular computer. On embedded devices with smaller displays, the visual rendering may end up extending outside of the screen, but it should still look pixel-for-pixel identical to the reference rendering. On devices with low power CPUs, the animation may end up being jerky, especially around..http://ln.hixie.ch/?start=1207212028&count=1 The performance aspect of Acid3- April 2, 2008 The Acid3 test says "To pass the test, a browser must use its default settings, the animation has to be smooth, the score has to end on 100100, and the final page has to look exactly, pixel for pixel, like this reference rendering". (Emphasis mine.) There has been some question as to what "the animation has to be smooth" means. The idea is to make sure that browsers focus on performance as well as standards. Performance isn't a standards-compliance issue, but it is something that affects all...http://ln.hixie.ch/?start=1207096078&count=1 |
