nearly all from the construction side is possible within freeway.
long answer:
some things are not to do (or harder to achieve) by the classical drop and drag method. Nearly all solutions with wide header and footer stuff (stretching all across the page) is going back into the boxmodel (or inline) construction that is frankly open spoken not always easy to learn and understand. But once understood, it’s a so cool method to achieve things like that.
The idea behind is, that there are divs that are set to 100% width. So assumed the page is 960px wide and an image 2000px wide is applied to this 100% div, it will be displayed in its complete width.
The pain? You need to set your page orientation in inspector to none what short means:
To center your page you need to incklick that 100% div, insert another div and set its margin to adjust, center horizontal (tick).
Playing that game exzessive you’ll finally have what you have:
where I add png images to box in box to simulate something like a layer effect. (heaven, cloud1, cloud2, sun …)
All this knowledge refers to Dan Jaskers Screencast “Boxmodel” that I always recommend. Some very very basic stuff I once screencast and can be found on my page too.
