Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

  <h2 class="full-width">Full-Width Bar Using Pseudo-Elements</h2>
  <p>Using :before and :after pseudo-elements, we can extend the apparent background of the h2 element beyond the &lt;section&gt; it's contained in.</p>
  <p>Unfortunately, this triggers a horizontal scrollbar, so we need to set both the html and body elements to overflow-x: hidden.</p>
  <p>Unless you need the added flexibility of styling both sides (different colors, heights, widths, gradients, etc.) there's a simpler approach using <a href="https://codepen.io/parkerbennett/pen/KwMwxr" target="_blank">negative margins and padding</a>.</p>
              /* both */
html, body {
  overflow-x: hidden;
body {
  background: #ccc;
section {
  box-sizing: border-box; /* or not */
  margin: 0 auto;
  width: 25rem;
  background: white;
  padding: 30px;
  padding-bottom: 60px;
.full-width {
  position: relative; /* child absolute */
  /* negative offset = section padding */
  margin: 0 -30px;
  /* add back section padding value */
  padding: .25rem 30px;
  background: #333;
  background: rgba(0,0,0,.8);
  color: white;
  font-size: 1.125rem;
.full-width:before, .full-width:after{

🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
