Support help question... how to get the stacked layouts

Problem/Motivation

Sorry for the question, been struggling with searching for the answer.

Can you please suggest how to get the old school bootstrap layouts such as the 1/2/1 stacked layouts in a single section? I have been searching and have not had much success.

Section X
|----------------|
|       1        |
|----------------|
|       |        |
|   1   |   2    |
|       |        |
|----------------|
|       1        |
|----------------|

Grateful for any suggestions.

The problem with recreating this with separate sections is that I get a padding/margin between sections that I cannot get rid of so it throws the spacing of my 1/2/1 off.
