User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312 In HTML 4.0 / CSS1 pages where <pre> text is enclosed within a <div>, such as the following page: <div style="background: #ff9999"> <pre> 1 2 3 4 5 6 7 1234567890123456789012345678901234567890123456789012345678901234567890 </pre> </div> if the browser window is resized to be too narrow to show all the <pre> text, the div background isn't drawn properly on the very right side of the browser window. It gets worse if the browser is then horizontally scrolled. Reproducible: Always Steps to Reproduce: 1. load page with above html code 2. horizontally shrink browser window, until window is too narrow to contain desired text. 3. grab horizontal scrollbar and drag it rightward. Actual Results: in 2, above, text is shown outside bounds of its enclosing <div> (in the narrow white margin on the extreme right side of the browser window). in 3, above, exposed area of <div> isn't drawn with div's background colour, so now more of the <pre> text appears to be outside its enclosing <div> Expected Results: 1. there shouldn't be that white margin on the right side of the div block when the window is too small - the div should go right the way to the end 2. text inside a div shouldn't be drawn outside it 3. the div background should be correctly drawn when it's exposed, as described above.
correction - the <pre> is irrelevant - this happens even without it, on pages like: <div style="background: #ff9999"> 1234567890123456789012345678901234567890123456789012345678901234567890 </div> If I were a betting man, I'd guess that the code which calculates the right extend of the div's background block is mistakenly using the width of the window (minus the margin size) rather than the width of the page (minus the margin size). Comparable implementations of CSS1 (Opera7, IE6) don't show the right margin in the window-too-small case - their divs go right the way to the very righthand edge of the window.
This reminds me a bit of bug 152273
