Hello!
I was wondering how to add the source button to infoboxes as shown on this page:
https://starwars.fandom.com/wiki/Thrawn:_Alliances
I would be planning to add it to the Berenstain Bears Wiki:
https://berenstainbears.fandom.com/wiki/Berenstain_Bears_Wiki
Also if possible I would like the edges to be rounded.
Thanks for the help!
