Very clever @firefoxwebdevs DevTools feature 🦊
When you go to a page from a file URL, with DevTools open, you can now map "https://firefox.localhost" to the file's parent folder.
So, now, I have "https://firefox.localhost" wired up to my Downloads folder. No servers. Thank you Firefox!

If you only use Baseline Widely Available ✅ features in your project, you’re missing out!
So many features you can use with fallbacks or as progressive enhancements.

Proud of this little trick. If you've started using CSS gap decorations, you might know you can inset the lines by some amount. Well, if you also use a CSS size container, you can inset the lines by, say, calc(50cqi - 2px) to get a 4px wid…
Do you know about WPT (Web Platform Tests): https://wpt.fyi ?
If so, do you know what it's for? Do you use the site? Would you want it to present other data, graphs, etc. to help you make decisions about your web development-related tasks?
Curious, is JavaScript runtime compatibility an issue these days? Rather, knowing which APIs are supported across different runtimes (Node, Bun, Deno, Netlify, etc.)?

If you have a Linux device with a Chromium-based browser installed on it, can you type `navigator.gpu` in the Console and tell me if this works?

navigator.clipboard.read() can be inefficient if the clipboard contains multiple representations of the same data, some really big and which you don't need.
