Making iframes be the right size is super awkward. I might actually use them more if they were easy to get responsive.

This post does link to a technique (new to me) to extract iframe contents:

    <iframe src="/example.html" onload="this.before((this.contentDocument.body||this.contentDocument).children[0]);this.remove()"></iframe>


I've come across this technique here [0] to try it on <object> elements, but sizing is even more difficult there.

Are we solving the information-centric transclusion problem, or the design-centric asset reuse problem? An iframe is fine for the former but is not geared towards design and layout solutions.


It kinda sucks for both! Dropping in a box of text that flatly does not resize to fit its contents does not fit the definition of "fine" for me, here.

You can do some really silly maneuvers with `window.postMessage` to communicate an expected size between the parent and frame on resize, but that's expensive and fiddly.
