WaniKani Audio Button Sizer
The button to play the sample audio is tiny and difficult to press. This makes it 30x30 on the screen and puts a black border around it to signify that you can click/tap anywhere inside the border. It’s literally one line of code to change the CSS, so hopefully it doesn’t cause any trouble with other scripts. This will be especially helpful in mobile cases, where your finger is probably 5 times larger than the pressable area on the screen.
