How to create 5 equal columns using SP Page Buidler?

Hi,
sorry it won't be easy, but search on Google tips how people done it for Boostrap 4 in general. Task for you.

But in SPPB 4.x it can be done pretty easy just from settings.

Hi,

If I may... There is no proper way to do this if you want to acquire fullwidth as per my knowledge.

However, you can consider the following structure if you wish!

1+2+2+2+2+2+1

The first and the last column will be empty in this case.

Best Regards
