how do I rotate an element on a webpage?

To rotate an element on a webpage, you can use CSS transformations. Specifically, the transform property allows you to apply a 2D or 3D transformation to an element. Here is an example of how you can rotate an element using CSS:

/* Rotate an element by 45 degrees */
.element {
  transform: rotate(45deg);
}

If you want to rotate an element using JavaScript, you can modify the transform property dynamically. Here is an example:

// Select the element
const element = document.querySelector('.element');

// Rotate the element by 45 degrees
element.style.transform = 'rotate(45deg)';

For more advanced 3D transformations, you might want to look into libraries like WebXR, which was discussed in the session Build immersive web experiences with WebXR. This session covers how to create immersive 3D experiences on the web, including handling transformations and animations in a 3D space.

If you are interested in learning more about integrating WebXR and handling 3D transformations, you can check out the chapter "Integrate WebXR" from the session Build immersive web experiences with WebXR.
