Slightly improved version of 960gridder. Now the overlay won't catch pointer events anymore, meaning that the overlay can stay visible while working on the DOM/CSS.

960gridder.js
/*
* Release: 1.3.1 2009-04-26
*/
/*
* Copyright (c) Andr?e Hansson (peolanha AT gmail DOT com)
* MIT License - http://www.opensource.org/licenses/mit-license.php
* Idea loosely based on JASH, http://billyreisinger.com/jash/
*
* Website: http://gridder.andreehansson.se/
*
* Changelog:
* - New GUI! The new GUI should be less obtrusive and has been repositioned.
* It is also featuring a slight delay on inputs so that you'll have a chance
* to change the settings before it is re-rendering the grid
* - Due to a lot of inquries regarding affiliation with jQuery the filenames has
* been changed, I'm very sorry for the inconvenience!
* - CSS issues with the GUI should also be fixed in more websites, please report
* in any issue you stumble upon
* - A small bug in IE that made the paragraph lines not position correctly has been
* fixed
* - A dropdown box has replaced the columns input box, 960 Gridder calculates the
* proper number of columns that can be used with the specified grid width
* - The 960 Gridder is now displaying perfectly (into the very pixels) in all
* A-grade browsers (according to browsershots.org)
* - An option to invert the gutters has been added, set this to 'true' if
* you want to use it, OR use the shortcut CTRL+ALT+A
* - Some other minor changes...
