My HTML code looks like this:
<div class="container-fluid">
<div class="row">
<div class="col-9">
<div class="container">...</div>
</div>
<div class="col-3">
<div class="container">...</div>
</div>
</div>
</div>
I am attempting to make the columns stack upon reaching a certain viewport width. I tried using
col-xs-12 col-sm-12 col-md-9 col-lg-9
for the first column and corresponding classes for the second, but it is not working as expected.
Here is my Bootstrap link in the head section:
