Text Alignment
In Bootstrap 4, text alignment can be easily controlled using a variety of utility classes. These classes help align text to the left, right, center, or justify it within a container. Here are the main text alignment classes and how to use them with examples:
Left Align
To align text to the left, use the class .text-left
.
<div class="text-left">
This text is aligned to the left.
</div>
Center Align
To center align text, use the class .text-center
.
<div class="text-center">
This text is centered.
</div>
Right Align
To align text to the right, use the class .text-right
.
<div class="text-right">
This text is aligned to the right.
</div>
Justify Align
To justify text, use the class .text-justify
.
<div class="text-justify">
This text is justified, meaning that the text is spread out so that each line has equal width, except the last line.
</div>
Responsive Text Alignment
Bootstrap 4 also provides classes for responsive text alignment. These classes adjust the text alignment based on the screen size. For example, you can left-align text on small screens and center it on larger screens.
<div class="text-sm-left text-md-center text-lg-right">
This text will be left-aligned on small screens, centered on medium screens, and right-aligned on large screens.
</div>

Example: Responsive Text Alignment
Here’s a complete example illustrating how text alignment changes with screen size.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet">
<title>Bootstrap 4 Text Alignment</title>
</head>
<body>
<div class="container mt-5">
<div class="text-sm-left text-md-center text-lg-right">
This text will be left-aligned on small screens, centered on medium screens, and right-aligned on large screens.
</div>
</div>
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
</body>
</html>
In this example:
- On devices smaller than 576px, the text is left-aligned.
- On devices 576px and larger, but smaller than 768px, the text is centered.
- On devices 768px and larger, the text is right-aligned.
These classes make it easy to manage text alignment across different screen sizes, ensuring a responsive and flexible design.
