Is there a WYSIWYG editor that will render inline, and linked stylesheets during editing?

Disclaimer: This question is not about fixing visual studio

So, I've used VSS for so long to edit HTML source that I actuall completely forgot there was a design view button. So for fun I clicked it. When I clicked it here is what I got.

Now, I fully expected it to look like crap since my styles are defined in separate css files. This got me wondering. Has there ever been a WYSIWYG editor that will render a page while editing using all stylesheets even external ones?

Solution

I think that WebPutty would help. You embed a WebPutty script on your site and it allows you to edit your CSS real-time and publish to your site as well right from WebPutty. It's not as powerful as Coda but does the trick if all you're concerned about is adjusting your CSS.
