通过添加一个clearfix实用程序,快速轻松地清除容器中的浮动内容。

通过添加.clearfix 到父元素可轻松清除floats 。也可以用作混音。

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

以下示例显示了如何使用clearfix。如果没有clearfix,则换行div不会跨越会导致布局破碎的按钮。

<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>
