Dark Mode & Images .svg.png: Invisible on Black Background

I think that’s right.

If you only consider Anki desktop and Ankimobile, you could probably use “reviewExtra” to set global CSS, but Ankiweb and AnkiDroid don’t seem to support "reviewExtra". I think it’s better to add the CSS to each note type.

It might be technically possible, but I think it would require complex javascript. The background-color property for <img> tag has no effect unless the images have a transparent background layer, so I don’t think it’s necessary to restrict the target images.
