The advantage of a grid system in HTML / CSS is that you have more control over your site. It makes you work faster and more exact.
Keep up the good work with grids! I've probably tried them all, but stuck with the easy and lightweight 1kb Grid. I don't need to remember widths...
Each time I try to look at a demo or preview I get a 404.
I’ve created a lot of websites during the years as a web developer and I don’t think HTML is perfect.
