Use of iframes should be banned. They can be used to solve any challenge in 88 characters

I haven't submitted one of these because it feels like it would be cheating but, by using an iframe, I can hit first place in almost any challenge with the same solution

<iframe src=/targets/124.png></iframe><style>*:not(style){all:unset;height:300;width:400

You can see in this screenshot that it displays correctly, too.

It won't let you submit :)

It's letting me submit, it's just showing a 0.3% match. I guess that's because images don't work? Either way, I guess this is a non-issue.
