CSS Style For Identifying Undescribed Media 

Recently, several users expressed a desire for a way to quickly check if the images in the toot they were about to boost were described. It would be nice if Mastodon itself offered warnings for that, as well as for forgetting to describe media in your own posts, but until then, this is actually one problem admins can fix on our own!
All you need to do is go into the site settings and add a bit of CSS code that will display a red border around any undescribed media. There are two examples available, depending on how subtle or noticeable you want the border to be; experiment and see what you like!
Thanks to @IngaLovinde for thinking of the starting code and @FiXato for improving on it! They did all the work here; I am just sharing this along.
Open this post in a new tab and look at the image to see how this can look like. The example image is my avatar, described in another pinned post.

@Mayana I can spread this around to some other instances too if you'd like.
