How to create unequal columns in Bootstrap ?
Last Updated :

Bootstrap is a responsive framework created by Twitter. It is used to create responsive sites. It has a pre-defined class and design. In Bootstrap, we can add pre-defined classes into the code without writing code. We also have a predefined “.col” class to create columns.
Grid Layout System: The whole working screen(desktop, tablet, mobile) is divided into 12 equal size rows. We can make unequal columns using the “col-number” class (pre-defined), where the number decides the ratio/size for that column and the number should be less than or equal to 12.
Step by step guide to implement unequal columns in bootstrap:
Step 1: Include Bootstrap and jQuery CDN into the <head> tag before all other stylesheets to load our CSS.
<link rel=”stylesheet” href=”https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css”>
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js”></script>
<script src=”https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js”></script>
<script src=”https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js”> </script>
Step 2: Add class with .col-3 and .col-6 class to have unequal divisions of columns.
<div class=".col-3">
<!-- Column 1 content -->
</div>
<div class=".col-6">
<!-- Column 2 content -->
</div>
Step 3: Add <div> tag with class container-fluid and also add another <div> with class .row to have all the unequal columns in one row.
Example 1: The following example will create a 25%/50%/25% split of unequal columns length.
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content=
"width=device-width, initial-scale=1">
<link rel="stylesheet" href=
<script src=
</script>
<script src=
</script>
<script src=
</script>
</head>
<body>
<div class="container-fluid">
<div class="row">
<! -- columns having unequal lengths -->
<! -- bg-success is background color -->
<div class="col-3 bg-success">col-3</div>
<div class="col-6 bg-warning">col-6</div>
<div class="col-3 bg-success">col-3</div>
</div>
</div>
</body>
</html>
|
Output:
25% /50%/ 25% split
Example 2: In the example below, we use two col elements, which get a width of 50% each of equal columns length. Bootstrap will recognize how many elements are present and accordingly create equal-width columns.
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content=
"width=device-width, initial-scale=1">
<link rel="stylesheet" href=
<script src=
</script>
<script src=
</script>
<script src=
</script>
</head>
<body>
<div class="container-fluid">
<div class="row">
<! -- columns of equal width -->
<! -- bg-success is bg color -->
<div class="col bg-success">col</div>
<div class="col bg-warning">col</div>
</div><br/>
<div class="row">
<! -- columns having unequal lengths -->
<! -- bg-success is background color -->
<div class="col-3 bg-success">col-3</div>
<div class="col-6 bg-warning">col-6</div>
<div class="col-3 bg-success">col-3</div>
</div>
</div>
</body>
</html>
|
Output:
row1:- 50%/50% split, row2:- 25%/50%/25% split
