<p>However, when the THREE.js scene does not take up the whole page, then placement of the <code>dat.GUI</code> becomes more awkward. The <a href="https://threejs.org/docs/api/geometries/SphereGeometry.html" rel="nofollow noreferrer">THREE.js docs</a> place examples in <code><iframe></code> tags which then forces the <code>dat.GUI</code> inside the frame, and hence inside the THREE.js scene. This looks great, but for me it is a problem since I have set the <code>X-Frame-Options: Deny</code> cookie.</p>

<p>How can I place the THREE.js scene and the <code>dat.GUI</code> in the same <code><div></code> with the same relative positioning as they would be if they occupied the entire page? Note that <a href="https://stackoverflow.com/questions/25653639/how-do-i-change-the-location-of-the-dat-gui-dropdown">this answer</a> does not work for me, since the styling is applied both to the THREE.js scene and the <code>dat.GUI</code>.</p>
