+description: Quickly and easily clear floated content within a container by adding a clearfix utility.
+group: utilities
+---
+
+Easily clear `float`s by adding `.clearfix` **to the parent element**. Can also be used as a mixin.
+
+```html
+<div class="clearfix">...</div>
+```
+
+```scss
+// Mixin itself
+@mixin clearfix() {
+  &::after {
+    display: block;
+    content: "";
+    clear: both;
+  }
+}
+
+// Usage as a mixin
+.element {
+  @include clearfix;
+}
+```
+
+The following example shows how the clearfix can be used. Without the clearfix the wrapping div would not span around the buttons which would cause a broken layout.
+
+{{< example >}}
+<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>
+</div>
+{{< /example >}}
