When trying to type
<span style="font-size:10px">
Anki on iPadOS uses “ instead of "… which is not accepted for the code to work.
In Safari for example, the symbols are the normal ".
Alternatively/additionally:
It would be pretty cool to also have a “text-size shortcut tool”, like in Ankidroid.
(I am not sure if there is a topic about this already, my english isn’t the greatest, so I don’t really know how to even look for it.)
