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
