CSS Hell
Yes exactly - usually in Artifacts, which I then copy and paste into the GitHub web editor in order to ship them via GitHub Pages to https://tools.simonwillison.net/

Firebase Studio
Exclusively HTML+JavaScript web apps. Many of the tools listed on https://tools.simonwillison.net/colophon were built on my phone - usually directly in the Claude app, then I copy and paste the resulting HTML into the GitHub web editor on https://github.com/simonw/tools/new/main to create the page.

I genuinely don't understand why some people are still bullish about LLMs
"When you use the LLM you may be productive quicker, but I don't think you can argue that you are really learning anything"
Here's some code I threw together without even looking at yesterday: https://github.com/simonw/tools/blob/main/incomplete-json-pr...
Reading it now, here are the things it can teach me:

Styling an HTML dialog modal to take the full height of the viewport
So for the https://tools.simonwillison.net/side-panel-dialog example - where clicking on an item opens up a "details" view in a side panel, which can then be dismissed - is the way I'm using dialog appropriate? If not, how should I use it instead?
Code is here: https://github.com/simonw/tools/blob/main/side-panel-dialog....
Key code is that when you click an item it effectively does this:
sidePanel.innerHTML = '...'; - Claude Token Counter

Thoughts on the Resiliency of Web Projects
This is one of the reasons all of the little tools I've been building on https://tools.simonwillison.net/ are Vanilla JavaScript, no React or anything that needs a build tool and only using dependencies if they can't be skipped.
I'm a server-side developer by trade, but there's something REALLY neat about being able to build a useful interactive thing as static HTML+JavaScript and know that it will effectively never stop working and is entirely self-contained.

Web Locks API
I do that a lot: most of the commits in that tools repo (which doubles as my "playing around with LLM generated code" repo) include links to the relevant conversations: https://github.com/simonw/tools/commits/main/

We saved engineering hours by writing tests with LLMs
Which of those did you think were dreck?
I think the source code for tools like this one is genuinely good code: https://github.com/simonw/tools/blob/main/extract-urls.html
What do you see that's wrong with that?

Everything I built with Claude Artifacts this week
Easiest is to use the "publish artifact" button, but that wraps them in a giant blob of obtuse React code which means they load slowly and view source is pretty much useless, e.g. https://claude.site/artifacts/46897436-e06e-4ccc-b8f4-3df90c...
Second easiest is to take the code and paste it in a Gist - like this: https://gist.github.com/simonw/14a2c3ef508839f26377707dbf5dd...
And then take the Gist ID and add it to this URL:
https://gistpreview.github.io/?14a2c3ef508839f26377707dbf5dd...
That gives you a URL you can load in your browser.
My preferred route is to host the generated HTML directly myself. I mainly use that via GitHub Pages - I can drop an extract-urls.html file into https://github.com/simonw/tools and about 20 seconds later it becomes available at https://tools.simonwillison.net/extract-urls
Those last two options only work for Artifacts that didn't use React (that's why I use "no react" in most of my artifact prompts). If you DID use React you can turn that into a standalone HTML and JavaScript app that you can deploy using https://github.com/claudio-silva/claude-artifact-runner - I wrote some notes on using that here: https://simonwillison.net/2024/Oct/23/claude-artifact-runner...
