If we pressed Super+/ key in the HTML file, the start and end lines will be surrounded with comments symbols.
But sometimes we need to make it comment line by line.

How do I make it?
I can’t find any packages or functions.

Thanks in advance.

Use multiple cursors instead - either drag with your middle click, or old down CMD (ctrl on win) + click where you want the cursors to go.

Then you can use your comment shortcut per line
