Comment (by ryelle):

 > For the admin colors, I'd love to do some sort of before/after
 comparison like @ryelle [https://ryelle.codes/core/colors/index.html has
 on her doc]. We'd need to figure out a lightweight and accessible
 approach. If there isn't one, worse comes to worse, I can make a
 before/after video.

 This uses a library called Juxtapose, and it's accessible according to my
 limited testing (I think I only tested keyboard use, not sure how a screen
 reader would handle it). So I think our options are:

 - Use Juxtapose via [https://juxtapose.knightlab.com/#make an iframe
 embed], they generate a URL iframe using images we upload. But that's a
 3rd-party embed, and might be unreliable/untrusted.
 - Use Juxtapose via a CDN, which is what I'm doing in the demo linked
 above. Again, possibly unreliable/untrusted code loading in wp-admin.
 - Use a CSS-only solution [https://codepen.io/ryelle/pen/OJbmbOL like
 this], but this requires a mouse to drag the resize bar. This is fairly
 "decorative" and the point would be clear from the default state, so
 perhaps this is OK?
 - No comparison slider, but use a button to toggle between two images.
 Much less interesting, and doesn't show the difference by default.

 If anyone has any other suggestions for something that can easily do this
 kind of comparison, please share - we don't want to introduce any new
 libraries into core just for the about page, but we can write some JS to
 the about page itself for the demo.
