So styles from 404 page are applied to main page. I've attached two files - one is common html page which includes missing CSS file using LINK tag. Other - is server response for 404 error (in my httpd.conf I have ErrorDocument 404 /404.html ) So if you will try to open that missing css - you will see 404.html as server response (HTTP code 404 is returned) 118383 1 29681 b30r4 2009-04-22 09:13:12 -0700 Created attachment 29681 web page with reference to missing CSS file 118384 2 29682 b30r4 2009-04-22 09:14:45 -0700 Created attachment 29682 server response for 404 error put this page somewhere at your web server and put ErrorDocument 404 /404.html into your web server config. replace "/404.html" with reference to current file. 118482 3 ap 2009-04-23 01:44:44 -0700 Duplicate of bug 15242? 118483 4 b30r4 2009-04-23 01:58:21 -0700 *** This bug has been marked as a duplicate of 15242 *** 29681 2009-04-22 09:13:12 -0700 2009-04-22 09:13:12 -0700 web page with reference to missing CSS file webkit.html text/plain 205 b30r4 PGh0bWw+DQo8aGVhZD4NCjxsaW5rIHR5cGU9InRleHQvY3NzIiByZWw9InN0eWxlc2hlZXQiIGhy ZWY9IjQwNC5jc3MiLz4gDQo8dGl0bGU+PC90aXRsZT4NCjwvaGVhZD4NCjxib2R5Pg0KPGgxPmlm IHRoaXMgdGV4dCBiYWNrZ3JvdW5kIGlzIHJlZCB0aGVuIHN0eWxlIGZyb20gNDA0IHJlc3BvbnNl IGlzIGFwcGxpZWQ8L2gxPg0KPC9ib2R5Pg0KPC9odG1sPg== 29682 2009-04-22 09:14:45 -0700 2009-04-22 09:14:45 -0700 server response for 404 error 404.html text/plain 116 b30r4 PGh0bWw+IA0KPGhlYWQ+IA0KICA8c3R5bGU+IA0KICAgIHAge30NCiAgICBoMSB7YmFja2dyb3Vu ZC1jb2xvcjogcmVkfQ0KICA8L3N0eWxlPiANCjwvaGVhZD4gDQo8Ym9keT48L2JvZHk+PC9odG1s PiA=
