We do recall of a method to do this with pure HTML/CSS, for doing drop-down menus, but that barely got any use and JS became so ubiquitous that everyone did it the JS way anyway.
You know what, we really need a pure HTML/CSS spoiler/content-warn-collapse HTML tag. It's a pretty common function, though admittedly the layout and structure of such things varies from website to website.
... and the thing it solves: activating JS to open read-mores on toot direct links, is moot when the up-to-date instances require JS to load anything (grump) anyway~.
Double ugh: turns out my CSS userstyle solution for thumbnail heights breaks spoilered/CW'ing images - collapses their height entirely and makes it look like there's no image there at all.
Current solution works, but - with letterboxing on - it introduces a small space underneath any short images, and doesn't centre tall images.
With letterboxing off the small space vanishes, but instead seems to cut off rounded corners instead. May have other weirdness too, hrm.
.media-gallery{
height: unset !important;
min-height: 0px !important;
max-height: 309px !important;
}
I don't like that generally the newest version of Mastodon, looking at other instances, is maybe trying to more be inviting to Twitter users. It has trending now! Don't you want to engage with the popular stuff, like all the normies~?
... man I still wish shorter-than-wide images were collapsed vertically though. At least on awoo, any image I post always takes up a full 16:9 space.

I talk about personal things that can get tangentially NSFW. While I wouldn't call this an after-dark account, it's kind of a mishmash personal account and prefer to mingle with people I know or trust.
