使用 CSS z-index 属性

# The z-index property is used with the position property to create layer effects. You can specify which element should be at the top and which element should be at the bottom.

Example

You can try running the following code to implement the z-index attribute -

<html>
   <head>
   </head>
   <body>
      <div style = "background-color:blue; width:300px; height:100px; position:relative; top:10px; left:80px; z-index:2">
      </div>
      <div style = "background-color:gray; width:300px; height:100px; position:relative; top:-60px; left:35px; z-index:1;">
      </div>
      <div style = "background-color:yellow; width:300px; height:100px; position:relative; top:-220px; left:120px; z-index:3;">
      </div>
   </body>
</html>
