CSS Pre-Processor for grid layouts and typography

A few posts ago I mentioned that I wasn’t entirely keen on the Blueprint CSS framework because of the way it was used. As with then I am not going enter into a discussion about the relative merits of Blueprint but I am going to present the initial concept (what will be an pre-alpha release if I develop it further) of my alternative.

What I wanted to use was something that would make it quicker to develop layouts using a grid, and simplify some of the type calculations but without reducing the level of control over the CSS, or messing with the content-presentation divide.

What I came up with was a PHP based CSS Pre-Processor that adds additional layout units (allowing layout according to grid columns instead of individual pixels) adds support for variables, and carries out the major typography calculations.

It is a long way from finished, but I think it shows some promise. If you do give it a look let me know what you think, if you had any problems, if you think it is a good idea, or if I am on the wrong track altogether. Thanks
