Thanks @marvinroger
We will need to also update this here https://github.com/styled-components/typescript-styled-plugin/blob/main/package.json as that’s where the intellisense is handled.

Testing this is explained here: https://github.com/styled-components/vscode-styled-components/blob/main/CONTRIBUTING.md#intellisense

I messed up the link in the description but it's already done styled-components/typescript-styled-plugin#19

This is why this PR is in draft

[jasonwilliams]

Ok great thanks, have you tested these changes locally?
I can take a look myself later

[marvinroger]

I did not test locally, but I can confirm that vscode-css-languageservice@6.2.11 does support container queries.
I'll let you test if you're OK with that 😉

https://www.npmjs.com/package/@styled/typescript-styled-plugin has been published

Thanks, just updated the PR!

Thanks for doing this!
I tried to test this locally (built the extension and installed to VSCode) but it doesn't seem to have an effect - I still see the following warning.

This is the first time I'm building/installing a VSCode extension locally so it's probably just me not doing it right, but wanted to let you know. Hope your own test goes well. I can try and share some small reproduction later if it will be of any help.

It also looks like @container queries should be supported in the latest version of VSCode (1.85) in .css files based on this Stack Overflow answer but that also doesn't seem to be the case for me either. Not sure what's up.

Yeah I've tested this branch and I'm still getting the warning too, are we sure this has been fixed in the styled plugin?
@marvinroger If you could make a fixture and add it to this branch which we can all look at that would help.

Sorry I know you've already done work in this repo but you may need to add a test here so we can be sure this has been fixed in the plugin before we try adding it to the extension.

I've also updated the main branch so you'll need to rebase if you can too

@macko911 I don't know how you set up before, but if you want to help fix this, I would say follow https://github.com/styled-components/vscode-styled-components/blob/main/CONTRIBUTING.md#intellisense

Then set some breakpoints in the styled plugin to see why its still warning about the unknown property at rule
