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.

+ add another resource

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.

              <!-- To use WebP images in normal HTML, just replace the image URL with that of your image, and the CSS class with your own class. -->

<h1>WEBP IMAGE DISPLAYED IN HTML</h1>

<picture>
  <source srcset="https://www.carmenhchung.com/images/carmen-chung.webp" type="image/webp" class="first-image">
  <source srcset="https://www.carmenhchung.com/images/carmen-chung.jpg" type="image/jpeg" class="first-image">
  <img alt="This is my face" src="https://www.carmenhchung.com/images/carmen-chung.jpg" class="first-image">
</picture>

<!-- Only do the following steps if you want to use an image inside a CSS class (e.g. as a backgroung image). -->

<!-- First, download Modernizr and save it to your directory. Refer to the location of your downloaded Modernizr script like below: -->

<script src="https://www.carmenhchung.com/modernizr-custom.js"></script>

<!-- Second, add the below command in to check if the user's browser supports WebP images: -->

<script>
  Modernizr.on('webp', function(result) {
    if (result) {
      // supported
    } else {
      // not-supported
    }
  });
</script>

<!-- Third, add a "no-js" class to every component in the event that the user's browser does not support Javascript (see JS file): -->

<html class="no-js">

<!-- Finally, display your actual class with the background image (see CSS file): -->
<h1>WEBP IMAGE DISPLAYED IN CSS</h1>
<div class="container"></div>

🕑 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.
