CSS Don’ts – behaviors

I was reading through some w3cschools stuff here:

[url]http://www.w3schools.com/css/css_dont.asp[/url]

and they have a section titled ‘CSS Don’ts’. One of the don’ts was to not use Internet Explorer Behaviors such as blah.htc.

I use hover.htc to support ie6 and below for my css drop downs…bad?

Also in #CSS _↴
