I’m reading different CSS sources to grasp a method to build up layouts and use always a standard method to starting new web project. This is my CSS starting rules with a different version I’ve found in the web, the question is there are difference between the two (eg. performance, different style, etc) ?

// one

  * {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
  }

// two

      *,
      *::before,
      *::after {
       margin: 0;
       padding: 0;
       box-sizing: border-box;
      }
