Hi Henry,

Btw, TopStyle Lite is the style sheets editor that comes with HomeSite 4.5=
=20
and has nothing to do with its internal Validator... ;-)
As for the errors, read on...

The reason that the latter bit of code is flagged as valid and the former=20
one is flagged as invalid is that header tags cannot be nested within=20
paragraph tags. More specifically, the error that was flagged here is that=
=20
the closing p tags after the closing header tags are considered orphaned=20
closing tags without opening tags by the validator because, since closing p=
=20
tags are optional, as soon as the header tag is opened, the preceding p=20
tag is considered closed (even if it's "empty") and the closing p tag after=
=20
the closing header tag is seen as missing an opening tag by the validator=20
(that's because p and hx tags are both block level elements that cannot be=
=20
nested). In this respect the W3C Validator's message was considerably more=
=20
helpful and should be considered the only 100% reliable validation=20
source. I myself use CSE HTML Validator Pro 4.5 within HomeSite and it=20
didn't flag an error either which is disappointing.
Dreamweaver was perfectly right in flagging the former code bit as invalid=
=20
so there's no need to modify its validation setting (which I don't think is=
=20
possible anyway). Out of curiosity, why would you want to insert header=20
tags within paragraph tags anyway? If it's to create more space between=20
those elements, additional <br> tags would fit the bill nicely without=20
breaking the logical structure of the document.
In any case, I hope my explanation was clear!
