In Composer, we use background images in our "Show All Tags" mode: 1. Start a new page 2. Click on "H.Line" toolbar button to insert an HR 3. Click on "Show All Tags" tab at botton of content window, or use menu: View | Show All Tags You should see a yellow icon with "HR" sideways. The CSS in the overlay style sheet for "Show All Tags" is: hr { min-height: 20px; margin-left: 2px; margin-top: 2px; padding-left: 17px; background-image: url(chrome://editor/content/images/tag-hr.gif); background-repeat: no-repeat; background-position: top left; } But the image is *not* starting at the left edge of the HR frame. If you double click on the HR in the Composer page, you get the properties dialog. Uncheck "3D shading" and click "Ok". That sets the "noshade" HTML attribute. Note that in Show All Tags mode, the solid rendering of the HR now hides the background image. I'll attach an HTML test file you can use in Viewer.

Reassigning to attinasi.

I've fixed this already. My fix is in bug 38370. Unfortunately that is blocked by some other bugs. Marking dependencies and taking bug. Note that the official result of mixing "noshade" with CSS properties is totally undefined, and my 'fix' doesn't do it the way IE does it. I'm open to suggested improvements.

Possibly related: A background image of a <table> element also doesn't appear in the correct place: <table style="background: url(blar.gif) 100% 100% no-repeat;" width=100% height=95% cellpadding=0 cellspacing=0 border=0> <tr><td>Some Text.</td></tr></table> ...is supposed to yield a single, untiled image in the bottom right corner of the table. Instead the image is simply tiled, starting from the top-left. [Mozilla/5.0 (X11; U; Linux 2.2.16 i686; en-US; rv:0.9) Gecko/20010505]

Bugs targeted at mozilla1.0 without the mozilla1.0 keyword moved to mozilla1.0.1 (you can query for this string to delete spam or retrieve the list of bugs I've moved)

This seems to work for me... the image starts in the right place.

Fixed by checkin for bug 38370
