Description

I read this post and found the start buttons to be misplaced on my Motorola Razr 50 Ultra, unfolded, using Firefox for Android. See screenshot showing embedded puzles.

I am seeing similar results when changing it to iPhone SE using Chromium DevTools. However, I'd be cautious in relying on DevTools as matching the resolution didn't emulate my Android view 1:1. The font that Android carries clearly affects size of the box in CSS.

You could decrease the horizontal padding on the button to fix this, unless you wanted to do it another way - as it may e.g. not meet your aesthetic goals.

The CSS controlling the widget can be found in this file: https://github.com/lichess-org/lila/blob/df66483def8cc81e5fea9aa37023a09b7cd09874/ui/bits/css/build/bits.lpv.scss#L6-L21

Research direction
The issue is a CSS bug in the embedded puzzle start button scaling on mobile. The file to modify is ui/bits/css/build/bits.lpv.scss (lines 6-21). A suggested fix is to decrease horizontal padding on the button. To reproduce, test on a mobile device or using Chrome DevTools device emulation (e.g., iPhone SE). Ensure the change works across different mobile screen sizes and browsers. No pull requests are linked, and the issue is unassigned, so it is available for contribution.
