'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

I personally find 0 cleaner than 0px. That's two extra characters that can add up. Why add extra bytes when you don't need to. I have see padding: 0px 0px 0px 0px which can easily be expressed as padding: 0 way too often.
