http://www.w3.org/Amaya/User/CSSStatus.html says: CSS 2: Parsed: Supported: ------------------------------ Margins Yes Ok. But this isn't entirely the case. ALMOST-CERTAIN CSS margin-bottom BUG {1} ======================================== * Amaya does not honor "body {margin-bottom:0}" (or "body {margin-bottom:0px}", nor the bottom-relevant aspect of "body {margin:0}", etc.) [See also forthcoming "Almost-certain CSS margin-bottom but {2}" for further proof]. Test: ----- http://www.well.com/~mech/.AmayaTest/NewTEST1.html (also attached here, with .css file, so you don't have to manually download that to look at it.) This test differs from ones sent yesterday and even earlier, in being more lean (the CSS has all unused properties removed), and being more strict in its HTML (*all* content is contained within DIVs, and *all* table cells have precentile height and width that add up to exactly 100% both horizontally and vertically. The stylesheet also uses 0-value "padding" and "border" properties, to eliminate any chance that these are in some way affecting Amaya's use of whitespace around the document canvas. If you remove them and test again, however, there is no difference in the rendering. I just include them as illustrative that it is "margin-bottom" and not something else, such as "padding[-*]" or "border[-*]", causing the problem. Description of the issue: ------------------------- There should be NO bottom margin at all on this page, yet there is a very large one. Amaya IS properly handling the left, right and top margins, just not the bottom one. I feel it is important for clarity to recap the following little bit here: At 10:30 AM +0200 2004/09/29, Irene Vatton wrote: > I see no error in the Amaya interpretation. > You see a big whitespace at the bottom when the html element is shorter > than the window. No, no... The very reason that I put a whole heck of a lot of dummy text in there was specifically to force the content to be taller than the window height, requiring you to scroll down to see the bottom of the page. It is NOT the case that the content all fits within the window vertically. That whitespace has no reason to be there. It is as if I had "body { margin-bottom: 50px }" in my stylesheet. (Well, if you have a truly amazing screen resolution, then perhaps the content DOES all fit in one screenful for you. I should have specified that I am working with a screen resolution of 1024x768 in these test examples. If you do have a super-duper monitor that I couldn't possibly afford :-) then simply double the amount of dummy text in the test HTML file and you'll get a test file that demonstrates the problem I'm documenting here.) At any rate, this seems to a pretty straightforward CSS implementation bug. As long as the content fills the page vertically, requiring scrolling to get to the bottom and the browser does not have to create a bottom "filler" pseudo-margin as it does for very short content (just like it does on the side if the content is very narrow) there should be **ZERO** margin at the bottom of the page, period. It's seems pretty clear that something is going on along the lines of Amaya's default border, that it puts around things when there is no CSS telling it not to, was forgotten about and not dealt with properly when it came to implementing "body {margin-right:0[units]}", and thus it is still operating when it definitely should not be.
