Use single-line comments for HTML & CSS

When commenting ctrl+/ in VSCode, it does block-comments normally for css & html, which can be bothersome when you end up with nested comments that don't actually nest. This will add a cursor to every line that's higlighted & do a single-line comment on every-single line. HTML & CSS don't have single-line comments like php (//comment), but at least the block comments won't wrap & nest & make everything hinky.

You can change that html|css|... bit to whatever file extensions you want to use this on. There are some funky results when using this, but I find it super helpful for html and css where all comments are /* block */ or <-- block --> comments.
