Why doesn't VS Code suggest css/vue and properties?

Question

Visual Studio Code

Hello. Why doesn't VS Code give hints on selectors?
I am creating a new div with class test. I save the HTML file with ctrl+s, but the css doesn't tell me that the class exists.
Not very convenient, especially if the class is large, not to mention that I create a new div with the class, and by the time I switch to css, I already forget what the class was called.



Vue 3 has the same problem. WebStorm issues hints, everything is fine. And VsCode is missing something.
In methods, I created the addNewTicker function, then I go to html to hang up the method call event on click on the element, and VSCode does not suggest that such an event exists. Uncomfortable.
