Morning all. Im not sure if this is already a recommendation, or its already been thought about, if not i would like to do so.
Basically i was working on a simple task, a 2 column layout heres the css: body {width: 50em;} div#mainNav {width: 10em;} div#content {width: 40em;} Now if i want to add a border, say 1px, i have to convert 1px to an em unit and minus that from the width values (40em-n), then add 1px border all around. It would take me a few seconds on the calculator, i know, but would it not be easier to have something like?: body {width: 50em; overflow: hidden;} div#mainNav {width: (10em - 1px);} div#content {width: (40em - 1px);} #mainNav, #content {border: red 1px solid; float: left;} Im sure there would be great use for it on larger and different tasks, the example i provided was very simple and probably not the best example. Basically the algorithm would automatically be able to convert between px, em, % etc. Just an idea, and im looking forward to any comments. Kind Regards. James Jeffery
