Assuming you know literally anything about CSS, yes, it is quite
obvious that that's what you do. "#foo" is an id selector.
If you don't know anything about CSS, I suggest learning at least the
basics. Attempting to do JS work without knowledge of CSS's abilities
will lead you to duplicate, badly, functionality already built into
