There is a webarchiver plugin in kdeaddons which, if installed, lets you fetch a webpage with images, etc. into an archivefile (zip or tag.gz I think).
If installed you find it in the Tools menu.

I just verified that it saves css, too.
The default file extension is .war,
and it's a gzipped tar archive(*).
The saved html page is renamed to index.html
inside the archive.
If you click on that archive in konqueror with
the option
View -> Use index.html
enabled then it'll display the saved web page in all its glory.
(*) This is a bit confusing because in the java world
a file with the extension .war is supposed to be
a jar file (zip format plus meta data)
