You're more then right.
Ok the problem is:
I wrote this HTML-code for the 960 12 colomns from the book I bought.
But when I check it in the browser it isnt correct. The blocks arent in the place were they need to be.
I tried everything to correct it in the code. But it isnt working.
I just started with CSS with help from the book of Jon Duckett. I try to work with the raster layout from 960.gs
I wrote the code from the book but the problem is the grid_4 are not appearing next to each other, but below each other.
Below here is the code I wrote. I cant find what I am...
