1. The margin abbreviation attribute sets all margin attributes in one statement. This attribute can have 1 to 4 values.
This shorthand property sets the width of all margins of an element, or sets the width of margins on each side.
The vertically adjacent margins of block-level elements will be merged, while inline elements will not actually occupy the top and bottom margins. The left and right margins of inline elements are not merged. Likewise, the margins of floated elements are not merged. It is allowed to specify negative margin values, but use caution when using them.
Margin allows negative values.
The example is as follows:
<html> <head> <style type="text/css"> p.margin {margin: 1cm 2cm 3cm 4cm} </style> </head> <body> <p>这个段落没有指定外边距。</p> <p class="margin">这个段落带有指定的外边距。这个段落带有指定的外边距。这个段落带有指定的外边距。这个段落带有指定的外边距。这个段落带有指定的外边距。</p> <p>这个段落没有指定外边距。</p> </body> </html>

The element's background extends across the padding. Negative margin values are not allowed.

The example is as follows:
<html> <head> <style type="text/css"> td.test1 {padding: 1.5cm} td.test2 {padding: 0.5cm 2.5cm} </style> </head> <body> <table border="1"> <tr> <td class="test1"> 这个表格单元的每个边拥有相等的内边距。 </td> </tr> </table> <br /> <table border="1"> <tr> <td class="test2"> 这个表格单元的上和下内边距是 0.5cm,左和右内边距是 2.5cm。 </td> </tr> </table> </body> </html>
Output result:
