Quick Tip: Multiple Borders with Simple CSS

Quick Tip: Multiple Borders with Simple CSS: "

Did you know that we can achieve multiple borders with simple CSS, by using the :after amd :before psuedo-classes? This is something I recently learned myself! I’ll show you how to add more depth to your designs, without images, in just a few minutes.

Final Code 

<!DOCTYPE html>

<html lang="en">
<head>
 <meta charset="utf-8">
 <title>Multi-Borders</title>
 <style>
  body { background: #d2d1d0; }

  #box {
   background: #f4f4f4;
   border: 1px solid #bbbbbb;
   width: 200px;
   height: 200px;
   margin: 60px auto;
   position: relative;
  }

  #box:before {
   border: 1px solid white;
   content: '';
   width: 198px;
   height: 198px;
   position: absolute;
  }

  #box:after {
   content: '';
   position: absolute;
   width: 196px;
   height: 196px;
   border: 1px solid #bbbbbb;
   left: 1px; top: 1px;
  }
 </style>

</head>
<body>
 <div id="box"></div>
</body>
</html>

In short, any browser that supports the :before and :after psuedo-elements (all major browsers) can take advantage of this effect. Of course, there are alternatives, including the use of box-shadow, as well as adding additional mark-up to the page; however, this is clean solution that you should definitely consider. Thanks for watching!
