Flux 6 is the latest release of the killer Web Design App for the Mac.
Flux 6 introduces support for Responsive design using Skeleton or Bootstrap, a totally revamped UI, and 100s of bug fixes and usability improvements.
A totally re-written Code Editor makes manual code adjustments easier than ever, and WYSIWYG changes to your pages are simpler too, with a clearer workflow.
Flux has an amazing WYSIWYG engine (What You See Is What You Get). In Flux, you don't need to code everything, or even anything, you can drag images onto your page, adjust sizes with the drag handles, even adjust CSS properties such as margins and padding. You can even adjust external CSS properties this way.
