This is especially true given that your friend is trying to create a Dreamweaver extension -- viewing the extension in a browser is totally irrelevant. However, how Dreamweaver renders extension dialogs is necessarily different from how it renders pages in Design view, and as Randy mentioned, there's no formal list of exactly what CSS is supported. [I'm not going to go into the differences between Design view and extension dialogs here, as this is already way off-topic.] There is, however, a reference for extension developers under the Help menu in DW that describes how to create extension UIs, and there are forums on both the Macromedia site and elsewhere where extension developers can get help. Those would be the best places to point your friend for help, IMHO. cheers, Lori ______________________________________________________________________ css-discuss [EMAIL PROTECTED] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
