CSS z-index property

z-index property in CSS is used to specify the stack order of an element.
Ex: Here we take an image as a background:
  1. <html>
  3. <head>
  4. <style type="text/css">
  5. img {
  6. position: absolute;
  7. left: 50px;
  8. top: 0px;
  9. z-index: -1;
  10. }
  11. </style>
  12. </head>
  14. <body>
  15. <img src="Penguins.jpg" width="100" height="100" />
  16. <p><b>My Name is Mahak Garg.</b></p>
  17. </body>
  19. </html>
