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.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

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.

  As this animation got a little bit more popular, it got some serious hate. I just want to point out that this is a proof of concept. Not following the best practices, accessibility, browser support... but showcasing what can be done using web technologies.
  <br/><br/>
  I was just playing with animations trying to reacreate <a target="_blank" href="https://uimovement.com/ui/6139/search-field/">this mockup</a> I was inspired by. Full animation works only in <a target="_blank" href="https://caniuse.com/#feat=css-caret-color">browsers supporting caret-color</a>.
  <br/><br/>
  You can read more about front end development on <a target="_blank" href="https://stanko.github.io">my blog</a>. I plan to write a follow up how this animation was created.
  <br/><br/>
  
  Cheers!
