Bootstrap is a popular front-end framework that provides a wide range of built-in classes and components to help developers create responsive, mobile-first web pages. One of the most common tasks when working with Bootstrap is to center an element on the screen. In this article, we will discuss how to make a div center of the screen using Bootstrap 5.
The first step in centering a div is to wrap it in a container. A container is a Bootstrap class that provides a responsive and fixed-width layout for the elements inside it. To create a container, you can use the .container class.
<div class="container">
<div id="center-div">
<!-- Content goes here -->
</div>
</div>
Once you have wrapped your div in a container, you can use the .d-flex and .justify-content-center classes to center the div horizontally. The .d-flex class makes the child elements of the container flex elements, and the .justify-content-center class centers the flex elements horizontally.
<div class="container d-flex justify-content-center">
<div id="center-div">
<!-- Content goes here -->
</div>
</div>
To center the div vertically, you can use the .align-items-center class. This class centers the flex elements vertically.
<div class="container d-flex justify-content-center align-items-center">
<div id="center-div">
<!-- Content goes here -->
</div>
</div>
You can also use .h-100 class along with .d-flex and .align-items-center class to make the div take the full height of the screen
<div class="container h-100 d-flex align-items-center">
<div id="center-div">
<!-- Content goes here -->
</div>
</div>
In summary, to center a div on the screen using Bootstrap 5, you need to:
- Wrap the
divin a container using the.containerclass. - Use the
.d-flex,.justify-content-center, and.align-items-centerclasses to center thedivhorizontally and vertically.
It's important to note that in order to use Bootstrap 5, you need to include the Bootstrap CSS and JavaScript files in your project. You can download them from the Bootstrap website or include them from a CDN.
Here is an example of a full HTML document that demonstrates how to center a div on the screen using Bootstrap 5.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0/dist/css/bootstrap.min.css">
</head>
<body>
<div class="container h-100 d-flex align-items-center">
<div id="center-div">
<h1>Hello World!</h1>
</div>
</
In addition to centering elements on the screen, Bootstrap 5 also provides a wide range of other built-in classes and components that can be used to create responsive, mobile-first web pages.
One of the most useful features of Bootstrap is its grid system, which allows developers to create responsive and flexible layouts by dividing the screen into a series of rows and columns. To create a grid, you can use the `.row` and `.col-*` classes. The `.col-*` classes are used to define the width of a column, with the number representing the number of columns the element should span.
Column 1
Column 2

In addition to the grid system, Bootstrap also provides a wide range of built-in CSS classes for typography, forms, buttons, tables, and more. These classes can be used to quickly and easily create professional-looking web pages without the need for custom CSS.
Bootstrap 5 also comes with a lot of utilities classes that you can use to quickly add styles to your elements. These classes include text alignment, spacing, visibility, and more.
<div class="text-center">This text is centered</div>
<div class="py-2">This element has padding on the top and bottom</div>
<div class="d-none d-md-block">This element is hidden on screens smaller than md</div>
Another great feature of Bootstrap is its support for responsive design. With Bootstrap, you can create web pages that automatically adjust their layout and content based on the size of the screen they are being viewed on. You can use the .d-*-* classes to show or hide elements based on the screen size.
In summary, Bootstrap 5 is a powerful front-end framework that provides a wide range of built-in classes and components for creating responsive, mobile-first web pages. With Bootstrap, you can easily center elements on the screen, create responsive and flexible layouts using the grid system, and add professional-looking styles to your web pages using the built-in CSS classes. Additionally, Bootstrap's responsive design features and utilities classes make it easy to create web pages that look great on any device.
