Thanks for opening this forum for us to supply feedback.
I would like to see an attribute added to borders that would allow the designer to choose whether the border was placed on the outside or inside of an element.
Choosing to place the border on the outside would apply the normal box model, but when it’s placed on the inside, the width of the border would be absorbed by the elements width, and the border would overlay the contents of element.
Too many times when designing liquid layouts have 1px borders thrown everything off because they make that element 2px wider and taller.
