  position: relative;
  border: 3px solid green;
}

  margin: 0;

}

  <div class="center">

  </div>
</div>

Example 4: css centraliz page

Use a container element and set a specific max-width.
A common width many websites use is 960px.
To actually center the page, add margin: auto.
The following example will center the website on screens that are wider than
500px.On screens that are less than 500px wide,
it will span the whole of the page:

<style>
.content {
  max-width: 500px;
  margin: auto;
}
</style>
<body>

<div class="content">
  <!-- Page content -->
</div>

</body>

Example 5: how to center div

<!DOCTYPE html>
<!--clearfix-->
<html>
<head>
<style>
div {
  border: 3px solid #4CAF50;
  padding: 5px;
}

.img1 {
  float: right;
}

.clearfix {
  overflow: auto;
}

.img2 {
  float: right;
}
</style>
</head>
<body>

<p>In this example, the image is taller than the element containing it, and it is floated, so it overflows outside of its container:</p>

<div>
  <img class="img1" src="pineapple.jpg" alt="Pineapple" width="170" height="170">
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus imperdiet, nulla et dictum interdum...
</div>

<p style="clear:right">Add a clearfix class with overflow: auto; to the containing element, to fix this problem:</p>

<div class="clearfix">
  <img class="img2" src="pineapple.jpg" alt="Pineapple" width="170" height="170">
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus imperdiet, nulla et dictum interdum...
</div>

</body>
</html>
