'property: 0' or 'property: 0px' in CSS?

Question

I\'ve seen this notation used a lot, and I was wondering, is there is any notable difference between these two notations?

element#id
{
  property: 0;
}
         


        

Answer 1

Zero of anything is zero. 0px = 0% = 0em = 0pt = 0

Most people leave the unit off because it is simply unnecessary clutter.
