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.

      <p>Update 2016 - This has been fixed - YAY! :)</p>   
<p>UPDATE 2015-11-25 -- It looks like a fix for this is in the pipeline: <a href="https://codereview.chromium.org/1457783005">Chromium issue details</a>. Yay!</p>      
			<p>Try resizing this page, the border between two colours should be smooth in most browsers with the dotted line and colour interface matching up. In Chrome the position of the colour change is incorrect and jumps around</p>
      <p>According to <a href="https://code.google.com/p/chromium/issues/detail?id=233879">this bug</a> it is due to Chrome splitting the gradient into 256 sections, and so getting rounding down errors.</p>
      <p>Discovered via <a href="http://stackoverflow.com/questions/23627292/">this Stack Overflow question</a></p>
      <p>Update: Chrome 43 the jumping has been reduced ... but compare this page in Chrome and IE / Firefox to see the difference in rendering.</p>

🕑 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.
