What steps must be taken to display a div element upon clicking an object or entity within an Aframe scene?

Experiencing some coding issues that I could use help with. As a newcomer to Javascript, I might be making a beginner's error here. My goal is for the red tree on the globe in my example to trigger a red div box when clicked. Despite my efforts, I keep encountering an error message in my console stating "Uncaught TypeError: Cannot read property 'style' of null". I have set up a Glitch with my code example. Any assistance would be greatly appreciated. Thank you in advance!

One way to create overlay elements is by utilizing the position: fixed property. This allows you to position them on top of the a-frame canvas, which occupies the entire screen.


When retrieving elements using getElementById, there is no need to include the # symbol.

Remember that when using document.querySelector:

  • Use . for classes
  • Use # for IDs

Additionally, your CSS selector is #Africa-Tree, while the corresponding div element is #Africa-Tree-Div.
