Version: (using KDE KDE 3.5.4) Installed from: FreeBSD Ports Compiler: gcc 3.4.6 OS: FreeBSD If the root element has display: table; and margin: auto; specified, Konqueror 3.5.4 will generate a bogus horizontal scrollbar. testcase: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"> <html> <head> <title>margin: auto and display: table on root</title> <style type="text/css"> html { margin: auto; display: table; } </style> </head> <body> <div>there should be no scrollbar</div> </body> </html> According to CSS 2.1 anonymous table model, the table computed width is shrink-to-fit in this case, with table-row-group, table-row, and table-cell anonymous elements autogenerated around the body descendant of root element with display: table; If the viewport width for a given font size is wider than the text in the body, the text should be centered on page. There should be no scrollbar. The problem occurs if the following display types are assigned to the root element: display: table; display: table-header-group; display: table-footer-group; display: table-row-group; display: table-row; display: table-cell; This is a spec violation in KHTML 3.5.4.
