CSS Grid Builder
I found this utility, CSS Grid Builder the other day on yahoo, It’s quite useful.
A simple interface for grids customization. Its a web based application thats easy to use and very user friendly. I used it to start a custom Wordpress Theme that I’ve been working on these last couple of days.
