### Installation

You can install this extension from the [Firefox](https://addons.mozilla.org/en-US/firefox/addon/dom3d/) and [Chrome](https://chromewebstore.google.com/detail/dom3d/lhdhfmkagpnfjjdgbionncpiolioknpj) extension stores or download the latest [release](https://github.com/OrionReed/dom3d/releases) and follow the instructions for your browser below.



Universal bookmarklet version

Simply prefix this code with `javascript:` and save it as a bookmark on Chrome or Firefox. This is a 1-1 equivalent to the full extension with the default configuration.



```js

(()=>{let e=t=>[...t.children].reduce((t,n)=>Math.max(t,e(n)),0)+1,t=e(document.body),n=(e,n=0,o=0)=>`hsl(${n}, 75%, ${Math.min(10+e*(1+60/t),90)+o}%)`,o=document.body;o.style.overflow="visible",o.style.transformStyle="preserve-3d",o.style.perspective=1e4;let r=window.innerWidth/2,i=window.innerHeight/2;o.style.perspectiveOrigin=o.style.transformOrigin=`${r}px ${i}px`,function e(t,o,r,i){for(let l=t.childNodes,s=l.length,d=0;d{let t=180*(1-e.clientY/window.innerHeight)-90,n=180*e.clientX/window.innerWidth-90;o.style.transform=`rotateX(${t}deg) rotateY(${n}deg)`})})();

```

## Development

1. Run `yarn install`

2. Run `yarn watch` to watch for changes and automatically rebuild the extension.

For Safari, you can run `xcrun safari-web-extension-converter dist/safari` and try to go from there. No success so far.



## Known Issues

All help in diagnosing and fixing these key issues is welcome! I've linked to an Issue for each of them.

- [The z-ordering of DOM elements from the 'cameras' perspective is incorrect in some cases.](https://github.com/OrionReed/dom3d/issues/9)

- [Some websites (like GitHub) appear flat when their DOM clearly isn't.](https://github.com/OrionReed/dom3d/issues/10)

- [Some elements don't increase stack height, such as `` and `` tags.](https://github.com/OrionReed/dom3d/issues/11)
