> So if I want to compare values to A1 or want a value lower than in A1, would I use =$a$1=min?
Populate B1:B4 with numbers and also enter a number in A1.
Select now B1:B4, use
=B1<$A$1
as the formula in cond format & select formatting you want.
Now any cell in B1:B4 with a value lower than the value in A1 will show the formatting you applied.
