Gutenberg - uneven columns
Go to your editor. Add 3 columns for example
Let’s say we want the first and last column at 10% width
Write for the COLUMN element the Additional CSS Class of first-last-10perc
Go to Dashboard > Customize > Extra css and enter
.first-last-10perc >.wp-block-column:first-child{
flex-basis: calc(10% - 16px);
}
.first-last-10perc >.wp-block-column:last-child{
flex-basis: calc(10% - 16px);
}
