CodePen probably won't work great in this browser. We generally only support the major desktop browsers like Chrome, Firefox, Safari, and Edge. Use this one at your own risk! If you're looking to test things, try looking at Pens/Projects in Debug View.
This is a quick rundown on how to use Twemoji (or Twemoji Awesome) so you can start adding emojis to your website or blog now! See accompanying post on implementation for Squarespace. Thanks to Twemoji team and Elle Kasai.
