I recently have been working on the site:

http://bh.gridrunners.com/
(also available at http://www.gridrunners.com/black_hat/)

And I've verified that every single part of it is 100% standards compliant, from the HTML output to the CSS. This has been checked against the w3c standards.

It shows up perfectly in Firefox (and all other browsers in the netscape family) and in Epiphany.

It shows up in Konqueror, but the <hr> tags are on the left side instead of centered. (I can live with that.)

But in Internet Explorer, Links, Lynx, Dillo, and Opera, the page doesn't display at all.

(Well, Opera shows corrupted HTML, and then on various pages it shows either broken or not at all, save for "contacts" and "404")

Any idea why this might be?

I've checked the source, checked the CSS, checked the output HTML... It's all 100% W3C-Standards-Compliant.

I've even tried right-click->view source... And it shows the source code just perfect!

But for some reason nothing works!

I've even hosted this on my own local Apache install, to see if it was the server, and it still didn't work!

Does anyone have any clue as to why this would happen?

Remove the XML declaration; IE and Lynx don't support it.

I think you'll find <script> needs a closing tag - try replacing

with

Browsers ought to ignore the XML declaration tag (although it's not entirely necessary on a webpage anyway).

I've done a test and this certainly works on lynx, dillo and links...

Links gives this error:

also, google returns this on a 400 error:

http://www.checkupdown.com/status/E400.html

i'm not an html guru, so i don't know if this helps

does it for me too

ie does have some problems with standards, i have a link around here somewhere....

I had the same problems recently and it was due to javascript problems. Neither Internet Explorer nor Firefox were able to display my pages, and everything I could see was blank pages.
I am also using XHTML sctrict and I kept my XML declaration which is fully supported by Lynx(and the like), Opera, Firefox, Mozilla, Internet Explorer.
Add a space between the script tag :
<script src="scripts.js" type="text/javascript"> </script>

You can also add an insecable space using the xml entity  :
<script src="scripts.js" type="text/javascript"> </script>

You do not need to remove the xml declaration.

Can't remove <?xml version="1.0" encoding="utf-8"?> because if I do then it's no longer 100% XHTML standards compliant.

However, changing <script src="scripts.js" type="text/javascript" /> to <script src="scripts.js" type="text/javascript"></script> fixed it for lynx... I'll check with the others.

Thanks for all the help!!

you may very well have other problems with javascript, like others have mentioned, but i still will share this link.. its good stuff to know if you are trying to work well on ie with standards compliant code.

Okay, checked with Dillo and Opera: it works!

Thanks everyone!
