Summary
Depending on the zoom level, the
sticky-header-containerleaves a 1px gap on the top.Problem
Refer to the following video:
stiky_header_1px_gap.mp4
Note that the viewport's top border has white dots.
Make sure you have the dark theme on. If you can not reproduce it, change the browser zoom level slightly and scroll so that some text reaches the top border of the viewport. Keep changing zoom till you see the gap. I can reproduce this in Firefox and Chrome.
Solution
This is due to some zoom levels producing fractions in the header dimensions, so a 1px gap remains after rounding. Pulling the header 1px up by using
top: -1pxshould cover the gap.How did you test this change?
In a browser before and after the fix.
