How to enable showing css hints in VS code?

Question

Visual Studio Code

Hello. When I first started using VS code, I set it up so that it was easier to write HTML, CSS, JS, PHP codes.
For example, as soon as I started typing .main, the tooltips came out (both php and css). After some updates to VS code. Such hints began to work incorrectly, and then they stopped altogether.
Now reinstalled VS code. I installed plugins, but the tips also do not come out. Installed plugin "IntelliSense for CSS class names in HTML", but it doesn't work quite as we would like. Hints come out, but when you press enter or tab, the correct class is simply inserted (i.e. ".main", not ).
Are there similar functions in VS code itself or can you recommend other plugins?
