I\'m trying to do a layout with bootstrap, but I can\'t figure it out what I\'m doing wrong. I\'m putting two columns of 6 and the second column of 6 I\'m putting 2 columns
You're just missing a basic Bootstrap "rule". From the docs..
In a grid layout, content must be placed within columns and only columns may be immediate children of rows.
In Bootstrap 4, .col-
that are not placed in .row
will stack vertically.
