Okay, so I want to use the Blueprint CSS framework for a website I’m working on.
Page width is worked out with this formula:
Total width = (number_of_columns * column_width) – margin_width
So, I want a page width as close to 950px as possible, but able to divide equally into 7 sections (for the main navigation). By default there are 24 columns, each 40px wide (including a 10px margin).
The answer — after about an hour of tapping keys on my calculator — is a frustratingly simple 910px.
Or 23 columns.
I should have paid more attention in my Certificate of Sixth Year Studies maths class.
I wish maths classes had been more practical. Sure, I can do differential equations until the cows come home … but I’ve no idea when I would actually need to do them!
