Just a few CSS grid resources I’ve been finding useful recently.
This article from A List Apart on fluid grids is a good starting point for learning the theory behind fluid grids and responsive design.
I came across the Frameless grid system recently – it’s not a frame work, just an idea for an adaptive grid system that you would code yourself. I like how it works, it seems very elegant and gets around the problems caused by resizing content quite nicely.
Another one from A List Apart is this article on infinite grids, it’s maybe a bit more advanced but has a lot of good info in it.
And don’t forget my post that demonstrates how I created a basic responsive grid!
