I’ve been studying CSS Grid Frameworks for the past couple weeks.  Here are some links to several CSS Frameworks that I found interesting, elegant, and useful:

• 960 Grid System – A mature and stable CSS Framework, that uses a fixed width page layout of 960 pixels, along with the flexibility of  12 or 16 columns.  (Created by Nathan Smith of  SonSpring)
• Blueprint – An elegant and complete CSS Framework that includes a CSS reset (similar to Eric Meyer’s Reset) that eliminates deals with the discrepancies across browsers, a solid grid that can support most complex layouts (without reverting to crazy HTML table-based design patterns), expert typographical principles, CSS form styles for great looking user interfaces, and CSS print styles for making any webpage ready for printing out on paper. (Created and maintained by Christian Montoya and the Blueprint community.)
• The Golden Grid – A simple CSS Framework for HTML web page design, by Vladimir Carrer from Italy
