I have an Angular Projekt and installed Tailwind 4 like described in the Framework Guide on the tailwind website.
But intellisense did not work.
Then i read again the instructions and saw that the stylesheet file, where i have to input - @import "tailwindcss" - must be a .css file.
So i had a .scss file. I changed this to .css and suddenly intellisense worked.

So it seems that tailwind 4 doesn't work with other stylesheet-file than .css

That's really bad, because for example the styling of Angular Material Components like it is recommended on the Angular Material Website works only with .scss.

If anyone have a solution for that problem, please write.
