      The clearfix hack has been around for a long time now, and patches a problem that can happen with floating elements that are larger than their container.

      Here’s an example of the problem:

      .box {
        padding: 1rem;
        background: rgba(255, 105, 180, 0.1);
        border: 3px dashed rgba(255, 105, 180, 0.1);
        border-radius: 5px;
      }
      .box img {
        float: left;
      }
      
      <div class="box">
        <img class="sammy" src="https://www.digitalocean.com/community/tutorials/Sammy_punk.svg" width="200" height="128" alt="Sammy!">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit...
      </div>
      
      Sammy!
      Lorem ipsum dolor sit amet, consectetur adipiscing elit…

      Old clearfix hacks

      The old fix was to set overflow: auto on the container, so a class like this is often created and used on elements that contain floated elements:

      .clearfix {
        overflow: auto;
      }
      
      <div class="box clearfix">
        <img class="sammy" src="https://www.digitalocean.com/community/tutorials/Sammy_punk.svg" width="200" height="128" alt="Sammy!">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit...
      </div>
      

      And now everything works as expected:

      Sammy!
      Lorem ipsum dolor sit amet, consectetur adipiscing elit…

      display: flow-root Improvements

      With display: flow-root on the container element, a new block formatting context is established for the element with flow layout formatting, and this fixes our overflowing issues much more elegantly.

      .box {
        display: flow-root;
        padding: 1rem;
        background: rgba(255, 213, 70, 0.1);
        border-bottom: 2px solid rgba(236, 198, 48, 0.2);
      }
      
      <div class="box">
        <img class="sammy" src="https://www.digitalocean.com/community/tutorials/Sammy_punk.svg" width="200" height="128" alt="Sammy!">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit...
      </div>
      
      Sammy!
      Lorem ipsum dolor sit amet, consectetur adipiscing elit…

      Browser Compatibility

      As of 2020, 87% of browsers worldwide will properly handle flow-root, based on Can I Use data. Opera Mini and Internet Explorer 11 cannot handle display: flow-root;, but in 2020 it makes up less than 1.5% of worldwide usage.
