CSS display issue on mobile

AnkiDroid (Android) Help

I’ve made a custom flashcard template that displays ruby text above Chinese characters.
And it works fine on PC with text displayed properly:

However, on my phone, the ruby text is displayed next to the character:

Screenshot_20250508_2243411096×1300 171 KB

This is made even more frustrating as I cannot even inspect element on my phone to see exactly what is going on.

Does anyone have any idea what can cause this behavior?

Thank you!

Have you considered using the built-in ruby character functionality? Learn more about that here.

Also, if you want to inspect the card, there is a way to do that on mobile.
