Eclipse and Impact... Whats the difference?
Eclipse and Impact are designed for two separate use cases and can actually be used in conjunction to help create dynamic and beautiful webpages.
The Eclipse stack gives your webpage full screen background image, slideshows or video while the Impact stack is placed within the foreground of your site creating promotional containers to fit your content.
Impact allows you to define the container size and then automatically crops images, slideshows, and/or videos to fit within the container.
Now go forth and make your websites great!
