When I want to use a class or an ID that i have previously written in my html file, the auto completion does not work. It does not either work in the same html file or in css or js files. Actually ctrl + space works in the same html file just for some classes, but not all of them, and also it is hard to always hit ctrl + space specially when it is not supposed to work always.

Here are the things I have tried:

• Updating VS Code
• Disabling all auto completion extensions
• Enabling different extensions one by one

I have searched so much and used different extensions, but none of them worked. Is there any solution somebody knows?
