VSCode warning for Tailwind Directives
I was running into an issue with VSCode warnings on CSS "Unknown at rule" for Tailwind directives.
./styles/globals.css
@tailwind base;
^^^^^^^^^
Unknown at rule @tailwind css(unknownAtRules)./styles/globals.css
@layer base {
* {
@apply text-gray-dark;
^^^^^^^^
Unknown at rule @apply css(unknownAtRules) }
}VSCode Solution: Define Custom Data for CSS
The solution was to load a custom CSS dataset for Tailwind directives in a workspace settings file settings.json.
A list of the different Tailwind Directives in the docs: Functions & Directives
Note: It's usually necessary to reload the VS Code window for the change to be recognized.
