By adding a clearfix utility easily clear floated content within a container.

Clear floats by adding .clearfix to the parent element. It can also be used as a mixin.

<div class="clearfix">...</div>
// Mixin itself
@mixin clearfix() {
  &::after {
    display: block;
    content: "";
    clear: both;

// Usage as a mixin
.element {
  @include clearfix;

Below example shows the usage of clearfix. Without the clearfix the wrapping div would not span around the buttons which results in a broken layout.

<div class="bg-info clearfix">
  <button type="button" class="btn btn-secondary float-left">Example Button floated left</button>
  <button type="button" class="btn btn-secondary float-right">Example Button floated right</button>
