For guidance on dealing with columns of varying heights, refer to Responsive column resets
To resolve any layout issues caused by varying column heights, consider using the following block of code:
<!-- Ensure proper spacing with an additional clearfix element for specific viewports -->
<div class="clearfix visible-xs-block"></div>
This snippet will help maintain correct column alignment during resizing and different layouts.
Alternatively, you can segregate your columns by encapsulating them within a div element like so:
<div class="row">...</div>
