Is there a way to check the CSS coverage list in vscode?

Is there a way to check the CSS coverage list in vscode?

throughout the workspace when editing css Is there a simple way to see how far it affects you?

For example, if there is a description of css below,

All parts of the class name class15 with span description in the child element are

from the entire project, not just within one html file Please let me know how to check the list and if there are any enhancements.

.class15span{
    color:#F00;
}

When I searched online, I came across the word xpath, but
I don't think I can use it with vscode, HTML, and CSS.

(Worst of all, it doesn't matter if you don't use vscode.)

Thank you for your cooperation.
