With DOCTYPE in place: Looks fine in IE6 CSS does not render in Firebird 0.7 Without DOCTYPE in place: Looks fine in IE6 Looks fine in Firebird 0.7, but now it's not valid xhtml :( Also, if I use Firebird to File->Save Page As and save the page, a) Firebird converts my xhtml compliant tags to html tags, and b) It renders the CSS just fine if I try to view the saved version. The DTD line I'm using is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> The stylesheet link I'm using is: <link rel="stylesheet" type="text/css" href="http://192.168.0.6/zamir/common/stylesheet.css" /> I have tried using a relative link to the CSS, to no avail. Reproducible: Always Steps to Reproduce: Not sure. It happens every time for me, but only on this 1 site I'm working on, and not other sites. I am developing everything on a Windows 2000 Professional box, with the latest installs of php, apache, and Firebird 0.7. I don't know what else I can say. It was working fine yesterday, and today it's not working at all. I haven't changed anything else. I spent 7 hours on this today, reading articles from alistapart.com, the Netscape dev centre, and W3C. Expected Results: Used the CSS to style all page elements. If you want, I can send you the file in a .zip, but there's no attach field on this form. I can't put it online, cause I only have localhost dev abilities, behind a firewall, and no webspace immediately available (I'm on contract in a foreign country).
Most likely the CSS is being served with the wrong MIME type. Mozilla will forgive this in quirks mode (no doctype) but in standards mode (such as this doctype) it will ignore the CSS unless it is served as text/css. Note that the text/css attribute value in the LINK tag makes no difference to this determination. The server has to get the MIME type right. There is a "create a new attachment" right here on the bug page if you wish/need to attach files.
Marking invalid. Please reopen if you have more information that demonstrates that this is a valid bug.
