Location Based Example

Try it live with this Codepen. It retrieves your position and places a text near you.

Please follow these simple steps:

Create a new project with the following snippet, and change add-your-latitude and add-your-longitude with your latitude and longitude, without the <>.
Run it on a server
Activate GPS on your phone and navigate to the example URL
Look around. You should see the text looking at you, appearing in the requested position, even if you look around and move the phone.
