Some Web sites are badly written, to the extent of crippling a browser. The first thing you
should do when you come to a site that looks as if it might have source code problems is try to
validate the Web page at the W3C's HTML validation service,
which will give you a rudimentary report, based on the standard of the type of document the Web page
claims to be, and how close to the standard the document actually is. If the Web page comes through
all right, there really should not be any problems with it in Opera.
