CSS study notes: Definition and use of parameters in Padding attribute_Experience exchange

I have always been quite confused about the definition of 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 viewed the CSS standard document, which stipulates this:
If only one is provided, it will be used for all four Side;
If two are provided, the first one is for top-bottom and the second one is for left-right;
If three are provided, the first one is for top and the second one is for left-right Right, and the third one is for bottom;
If all four parameter values ​​are provided, it will act on the four sides in the order of top-right-bottom-left.
body { padding: 36px;} //The patch margins on all four sides of the object are 36px
body { padding: 36px 24px; }
//The patch margins on the top and bottom sides are 36px, and the patches on the left and right sides are 36px. The margins are 24px
body { padding: 36px 24px 18px; }
//The patch margins on the top and bottom sides are 36px and 18px respectively, and the patch margins on 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, 12px respectively

Make a mark, I forgot.
