I'm not a designer but I'm learning how to implement an efficient design on a website. How do we decide on the grid used, as far as I can grasp, 3x3 boxes looks good to me. But as I keep reading, i noticed there are many more grid variations such as 12x12, 16x16. If so, where will the "focus" point lie in the website?
In a 3x3 Grid, I understand that the "focus" point lies between the two horizontal line intersecting with one of the vertical line.
