I realize the question of a good CSS editor has been asked dozens of times here on StackOverflow. However, I am specifically looking for one that has preview functionality for a variety of browser rendering engines.
Most importantly, it MUST be able to render IE6, IE7, and Safari 3.0. Price is not a factor. I have been looking at Aptana, Stylizer, and TopStyle, but I'd rather not go around downloading a bunch of trials only to find that none of them will do what I'm looking for.
Thanks!
With the new Expression Web from Microsoft, you get the SuperPreview, which will render in multible browsers, including IE6-8 and FF
You may want to take a look at Expression Web 3, especially at SuperPreview:
SuperPreview
Expression Web provides new tools to make sure that the pages in your site work in multiple browsers.
Using SuperPreview, you can preview and compare pages simultaneously in multiple browsers, even in multiple versions of Internet Explorer. You can also compare browser views against a comprehensive mock-up ("comp") image.
You can select individual elements within a page and see details about each selected element, helping you quickly find and fix cross-browser layout and positioning errors.
Basically it's a side-by-side or overlapping view on steroids which is also able to track each element from your page and where it goes in different browsers.
