Flux is an advanced HTML5 Web design application, capable of creating stunning sites from scratch. Flux isn't a template based solution, it's a creative design environment.
Flux has an amazing WYSIWYG rendering engine, which means you can drag, stretch, and move objects like a you can in a DTP application, and your webpages will look exactly how you intended.*Flux will generate all the code for you, with no unneccesary tags.
Size, position, even margins and padding can be altered with handles on the elements themselves. If the properties are stored in external CSS stylesheets, these are automaticaly updated.
