How to Left align and right align within div in Bootstrap 5

When we add elements to a <div>, they are generally placed at the left of the page. We can change the alignment of the elements using alignments utilities. Let us explore the classes used to align the div element to left and right.

Float Class

The float classes in the bootstrap are used to float the element to the left or right of the containing block.

  • The .float-start class is used to left-align the elements
  • The .float-end class is used to right-align the elements.

Example: Left align and Right align using Float class

Here, we have used the float classes to align the element within <div>. If you are using a non grid element then don't forget to wrap float classes under the .clearfix class.

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap </title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.1/dist/css/bootstrap.min.css" rel="stylesheet"> 
  <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js" integrity="sha384-IQsoLXl5PILFhosVNubq5LC7Qb9DXgDA9i+tQ8Zj3iwWAwPtgFTxbJ8NT4GN1R8p" crossorigin="anonymous"></script>

</head>
<body>
  <div class="clearfix bg-secondary">
    <div class="float-start">left align</div>
    <div class="float-end">Right align</div>
  </div>
</body>
</html>

Output:

left right aligned

So you can see in the output that the elements are aligned to the left and right sides.

Flexbox Alignment utilities

The flexbox alignment utilities can also be used to align the elements within <div> to left and right.

The .justify-content-between class is used for this purpose.

			<div >Left align</div>
			<div>Right align</div>
	  </div>
		  
</body>
