How to make an element width: 100% minus padding?

HTML Web Development Front End Technology

Let?s say we have padding: 50px 10px; for the input and want it to be 100% of the parent div's width. Using width: 100%; is not working. To fix it, we can place the input in a div with position: relative and a fixed height. This will form the element width to be 100% minus padding.

We have set the position to be relative with fixed height ?

.container {
   position: relative;
   height: 30px;
}

The position of the input is set absolute ?

content {
   position: absolute;
   left: 0;
   right: 0;
   padding: 3px 10px;
}

Example

Let us see the complete example ?


<!DOCTYPE html>
<html>
<head>
   <style>
      .demo {
         border: thin solid orange;
      }
      .container {
         position: relative;
         height: 30px;
      }
      .content {
         position: absolute;
         left: 0;
         right: 0;
         padding: 3px 10px;
      }
   </style>
</head>
<body>
   <h1>Fix</h1>
   <div class="demo">
      Lorem ipsum dolor sit amet, consectetur adipiscing elit.
      <div class="container">
         <input class="content" type="text" />
      </div>
      Nunc auctor efficitur sapien, luctus faucibus mi dictum nec.
   </div>
</body>
</html>
