If you want to change the size of a single column, you can use one of the following classes:

• is-three-quarters
• is-two-thirds
• is-half
• is-one-third
• is-one-quarter
• is-full

The other columns will fill up the remaining space automatically.

You can now use the following multiples of 20% as well:

• is-four-fifths
• is-three-fifths
• is-two-fifths
• is-one-fifth

As the grid can be divided into 12 columns, there are size classes for each division:

• is-1
• is-2
• is-3
• is-4
• is-5
• is-6
• is-7
• is-8
• is-9
• is-10
• is-11
• is-12
