First of all, we need to know that padding represents the blank distance between the element and its border. Then let's look at the picture above. We set the padding 10px style attribute for the text in the div block p1, which increases the distance between this text and the red borders on all four sides by 10 pixels. Then we added padding: 20 30px; style attributes to p2, which means that the top and bottom margins of the text field are 20px; the left and right margins are 30px.

Let’s continue to look at the padding: 10px 5px 15px added in p3 The style attributes of 20px; here respectively indicate that the top padding of this text is 10px, the right padding is 5px, the bottom padding is 15px, and the left padding is 20px.

The top, bottom, left, and right padding settings here can also be written separately, such as padding-top, padding-left, padding-bottom, and padding-right.

Note: CSS style inner margin padding cannot be set to negative values!
