Pen Settings

CSS Base

Vendor Prefixing

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.

Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

Auto-Updating Preview

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.

              <div class="codepen-container">


<div class="codepen-container">

<!-- pattern markup -->
<label for="this-field" class="input-text">
  <span class="field-name">Field Name <abbr title="required">- required</abbr></span>  
  <input type="text" name="this-field" id="this-field" />  
<span class="field-help">forgot your name?</span>
<!-- /pattern markup -->

<!-- Two closing divs - not an error -->
              /* THIS JS IS NOT PART OF ENTERPRISE. It is for administrative use only. */ 

/* Uncomment first section to activate blackout on this pen ONLY. The alternative would be to change classes in "_Codepen container" to enact a blackout across ALL pattern pens. 

Uncomment the second section, with new text, if message to viewer needs to be tailored for a blackout on only this pen. */

// blackout
$('div.blackout, p.top-layer-info').addClass('active');
$('div.blackout, p.top-layer-info').removeClass('hide');

// change message to viewer
$('p.top-layer-info').text('Sorry for any inconvenience; thanks for your patience while we update this pen.');
🕑 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.
