Any experiences in prototyping with justinmind prototyper creating custom html/css components?

Assuming to have a corp.design-styleguide with lots of div-containers and div-widgets in html with images and css-styling and jquery and so on.

Is it possible to define such widgets as HTML-widgets in justinmind prototyper? how can I underlay specific images and 开发者_StackOverflowcss to such a custom component? til now, I haven't found a way to do this. is it possible or not? any desktop prototyping tool known to rock such tasks?

You can use the "HTML Website" widget to include a folder with the html, the images and all the css files.
