Applying conditional formatting to cell based on another cell's in

Is this even possible? I've done conditional formatting to a cell based on
that same cell's info BUT what I want to do now is something like this...Can
I apply conditional formatting to cell A3 based on the information in cell
B3? If so, how do I do that?? I completely suck at writing formulas so, if
you know the answer, can you help me with how to write the formula, too?
Basically, I want to apply formatting to A3 if B3 has a value greater than
zero. Thank you!!

use "Formula is" and the formula is

=B3>0
