Thanks for Wanikani, it’s a very good way to learn for me.
Could you explain me the rationale behind the fact that you have implemented maximum-scale=1.0 and user-scalable=no in the site’s meta viewport tag?
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
It prevents user zooming in mobile conditions and I find it greatly decreases usability on tablet or mobile. After a review, the items in the “Answered correctly” and “Answered incorrectly” are very small and being able to zoom would be really useful.
I know you don’t wish to support mobile devices, but using this viewport settings means actively worsening their experience: https://a11yproject.com/posts/never-use-maximum-scale/
