I finally made a 3D renderer of web page DOMs. It allows you to travel through the DOM in 3D by using your mouse. Zoom by scroll, rotate with left, move with right click. Here is http://google.com: https://thelaboflieven.info/show3D.html<p>It's based on THREE.js. Full code can be found here:<p>https://github.com/denshade/3DwebsiteRender
Firefox used to have an extension that would do this for any webpage, and I found it was the easiest tool for finding which element was causing a horizontal scrollbar on the page.
