Rows aren't collapsing on mobile view - html

Question

My bootstrap rows are not stacking on top of each other in mobile view. I have a row of 3 cols and a row of 4 cols. The rows that aren't collapsing are the .about-content row in the #about section and 4 col row is in the #member section. Any help would be appreciated, Thanks!

Answer 1

They aren't collapsing because you specified them to be uncollapsable.
col-xs-* means at the smallest screen.
So, 3x col-xs-4 is 12 which is a full row.
