Extending Bootstrap V3 - More Columns


Download Bootstrap's source and find the variables.less file

Find the variable: @grid-columns and change it to the number of columns you need.

I like 24 columns, it doubles the possibilities and keeps the maths easy for working out how wide your columns are going to be.

I have found that the more columns you have you have to play with the easier it it to show a lot of data/content on a screen.
