yes, but does exactly what your example needed.

In any case, it's very common to find that rule in most css files and

You wanted a file tree to collapse or expand tree nodes and that is best 
served on the client via javascript.

so you don't need to waste bandwidth?

Think GMail:  they serve a mostly static page containing complex 
javascript that then occasionally asks the server to check for new data 
and then have those small data changes served rather than process lots 
of html and server side languages just to serve a tiny bit of changed data.
