I would like to margin-left:auto; margin-right:auto > 100% - 10px, where the border of the box is 5px. This way one could Size is measured outside of the border, so I don't see that this case serves any useful purpose. Whenever you think you need px units, you should question very carefully whether you really do, as the use of such units tends to create device dependence and may suggest that text also needs to be an absolute size, which is an accessibility no-no. > ensure that the box (including borders) would be 100% of the containing > container. Calculated sizes have been proposed on many occasions, and I believe they are already in the current CSS3 proposal, albeit, as a special function. The main concern tends to be to avoid getting anything like the power of scripting, with the associated security problems.
