Definition and use of parameters in the padding attribute of CSS learning notes

It is always confusing to define the number of parameters in the padding attribute in CSS. For example:
Body {padding: 32px ;}
Body {padding: 32px 24px ;}
Body {padding: 32px 24px 18px ;}
Body {padding: 32px 24px 18px 12px ;}

Today, Baidu has checked the standard CSS documentation, which stipulates:
If only one edge is provided, all four edges are used;
If two values are provided, the first value is used for top-bottom and the second value is used for left-right;
If three are provided, the first is used for the top, the second is used for the left-right, and the third is used for the bottom;
If all four parameter values are provided, the top-right-bottom-left parameters are added to the four sides.
Body {padding: 36px;} // The patch margins on the four sides of the object are all 36px
Body {padding: 36px 24px ;}
// The patch margin on both the top and bottom sides is 36px, and the patch margin on both sides is 24px.
Body {padding: 36px 24px 18px ;}
// The patch margins of the top and bottom sides are 36px and 18px respectively, and the patch margins of the left and right sides are 24px.
Body {padding: 36px 24px 18px 12px ;}
// The top, right, bottom, and left patch margins are 36px, 24px, 18px, and 12px, respectively.

Make a mark and the table is forgotten.
