+### Gutters
+
+Gutters can be responsively adjusted by breakpoint-specific padding and negative margin utility classes. To change the gutters in a given row, pair a negative margin utility on the `.row` and matching padding utilities on the `.col`s.

+Here's an example of customizing the Bootstrap grid at the large (`lg`) breakpoint and above. We've increased the `.col` padding with `.px-lg-5` and then counteracted that with `.mx-lg-n5` on the parent `.row`.
+
+{% capture example %}
+<div class="row mx-lg-n5">
+  <div class="col py-3 px-lg-5 border bg-light">Custom column padding</div>
