Chrome 153 ships a new <camera> element that can restore previously blocked camera access. I found camera.error can retain an old NotAllowedError even after a successful retry. Demo + Chromium issue: mcslayer.com/articles/cam...

mcslayer.com

The browser's own camera button: testing <camera>

Testing the <camera> element in Chrome 153: it restores access a user already blocked, and camera.error keeps reporting an old failure.

Thank you, I really appreciate that :)

There is :) At the bottom of every page, in the footer, there’s a short bit about me and a link to my personal website.

Anyway, if you find something wrong in the content, please tell me. Seriously. I'm happy to check it, fix mistakes, and make the site better. And if not, thanks for the feedback anyway. Maybe I just need to rethink the design a bit :)

So I was genuinely a bit surprised by the reaction here. Not because I expected everyone to like the site, but because so much of the discussion seems to stop at "AI made this." There was a lot more work behind it than that, and I guess I wish that part had been noticed too.

I also thought about when you'd actually want to use each unit and when you probably shouldn't. Claude helped me turn that into a better-looking site and better English. That's how I see these tools: not as a replacement for doing the work, but as help with the parts where you need it.

But it wasn't "make me a site about CSS units" and then publish whatever it gave me. Far from it. I did the research and put together the structure and content myself. I thought through how to explain each unit, what examples to use, and what the pros and cons are.

Hey, this is my site, so I thought I should jump in here. Yes, Claude helped me build it. I'm not a designer and English isn't my first language, so I used it mostly for the design and to help me phrase things naturally in English.

Think CSS units are just px, %, and rem? There are 63. CSS Units explains every one with live examples and the gotchas nobody warns you about. Like why 100vh can be taller than your phone screen, or why ch doesn’t count characters. Read it online or download the PDF: cssunits.com

Ha, same :) that itch is exactly why I ended up writing a whole book about them. My favourite from that family: Q = ¼mm, from the Japanese kyū (級) cssunits.com/article/abso...

Absolute Units — CSS Units

px, cm, mm, in, pt, pc and Q, all anchored to 1in = 96px. Why absolute units stop being physical the moment they hit a screen, and where each one still earns its place.

Yes, but it's a bit tricky. Hold a ruler to your monitor and measure a 1cm div. It won't match: the CSS cm is calibrated to the reference pixel, not your screen. Which is exactly why cm/mm are print units: @page { margin: 2cm } is the one place they mean what they say. cssunits.com/article/abso...
