max-width media query not applying to max value

I have an odd issue where my max-width media query; eg: @media (max-width: 1023px) is working on everything below <1022px, but at 1023px, it doesn't apply. I have checked dev tools and confirmed this issue. There does not appear to be another media query (eg: @media (min-width: 1023px)) being applied. I know my issue is impossible to diagnose without code, but does anyone know general reasons why this could be happening? I read MDN and it should be applying <=1023.

Potentially helpful screenshots from devtools: 1022px browser width (first image) 1023px browser width (second image)

Very strange! Is there any possibility some sort of non-integer display scaling is leading to rounding errors in the browser? What happens if you go sub-pixel? i.e. 1023.01px or 1023.99px or something in between?

Hey @Jacord, thanks for the response! I tried 1023.01 and 1023.99 based off your suggestion - .01 had the same behavior and .99 made it behave like it was a media (max-width: 1024px) 🤔 I just tried 1023.5 to test and that actually fixed the issue lol

😂 Thanks a ton, I'll have to check out display scaling issues because I've never heard of that stuff before. I always assumed whatever was shown as the width/height in responsive mode was what it said it was

Me neither to be honest! I was just wondering if it might have played a part... I bet it's something simpler than that, but if it's working the way you want it to for now hopefully it can spare you some headache until the answer shows up.

I appreciate you! 🙂 Interesting write up here: https://www.stevefenton.co.uk/blog/2023/05/unintentional-media-query-gaps/ Doesn't really apply to my case, but might be part of the pixel rendering issue. That article links to this article: https://alistapart.com/article/a-pixel-identity-crisis/ (which I'd love to read but frankly can't be assed atm 😂)

That was an interesting read... much of it lines up with my existing frustrations with what has happened to reliable ole pixel.
