Bootstrap button sizes examples
Hi Friends 👋,
Welcome To aGuideHub! ❤️
In this article, I will show to button size examples in bootstrep with step by step guide.
Here, we will use btn-lg, btn-sm, and btn-xs
class to make a button in size.
You can very easily change button size by adding btn-lg btn-sm and btn-xs
class to it. These classes modify button’s padding and also the font size.
Let’s look at the following example to understand how it basically works:
<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- Bootstrap CSS -->
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<title>Buttons</title>
</head>
<body>
<button type="button" class="btn btn-success btn-lg">Large</button>
<button type="button" class="btn btn-primary">Normal</button>
<button type="button" class="btn btn-warning btn-sm">Small</button>
<button type="button" class="btn btn-danger btn-xs">XSmall</button>
<!-- Bootstrap Bundle with Popper -->
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script>
</body>
</html>
In the above code, we have used btn-lg
btn-sm
and btn-xs
class to center the button.
Check the output of the above code example.

All the best 👍
