HTML+CSS Easy to Start Box Model Filling

The distance between the element content and the border can be set, which is called "filling". Filling can also be divided into upper, right, lower and left (clockwise)

Let’s write an example below:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title></title>
  <style type="text/css">
      div{
       width:200px;
       height:100px;
       border:1px solid red;
       padding:10px 10px 10px 10px;
      }
  </style>
</head>
<body>
    <div>php中文网</div>
</body>
</html>

In fact, it can also be written like this

div{
    padding-top:10px;
    padding-right:10px;
    padding-buttom:10px;
    padding-left:10px;
}

If they are all You can also write like this

padding:10px;

The order is top right bottom left

If the upper and lower values are the same and the left and right values are the same, you can write like this

padding：10px 20px;
