I have created a webpage (http://www.snow4life.yum.pl) that was rendered properly in firefox, chrome etc. Of course dumb IE complicated things, because it enters quirk mode automatically, even though doctype is properly set and site goes through w3 validation (there is one error of missing some char, but file was cleared in hex editor). How can I stop ie from entering quirks mode ? Is there any way ?
Try killing all the whitespace before the DOCTYPE.
EDIT: There is an <feff>
character which is a Unicode BOM signature at the start of the file. Since you may not have a text editor that can actually see that, try deleting the entire first line and paste over it with
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
And do NOT save the file with a BOM unicode signature. If this doesn't work, try a different text editor altogether.
