A utility that controls the contents of descendant files from a single css file

Question

css

Let's say we have a completely standard block

<!--[if lt IE 7]><link rel="stylesheet" href="css/ie6.css"><![endif]-->
<!--[if IE 7]><link rel="stylesheet" href="css/ie7.css"><![endif]-->
<!--[if IE 8]><link rel="stylesheet" href="css/ie8.css"><![endif]-->
<!--[if gt IE 8]><!--><link rel="stylesheet" href="css/ie9.css"><!--<![endif]-->
<link rel="stylesheet" href="css/otherbrowsers.css">

All files ie[6-9].cssare essentially copies otherbrowsers.csswith the appropriate hacks. Suppose we have edited otherbrowsers.css, is there a tool in nature that will add the appropriate changes to the descendant files, of course, if the browser version supports them, and if not, will it let me know about it and offer to make the appropriate edits with the handles?

Answer 1

And what kind of file comparator will not work? The same Meld diff, araxis merge, beyond compare, etc. Since they have common parts, the comparator will find them, you will indicate what to transfer where and that's it.
