Bootstrap is a popular front-end framework that provides a fast and easy way to create responsive websites and web applications. It's built with HTML, CSS, and JavaScript and it offers a variety of pre-designed components that can be easily customized to fit your needs.
One of the main advantages of Bootstrap is that it is built on a responsive grid system. This means that the layout and alignment of content automatically adjusts to fit the screen size of the device it is being viewed on. This is particularly useful for creating websites and web applications that need to look good on both desktop and mobile devices.
Here are 10 tips for getting started with Bootstrap:
Add Bootstrap to your project
There are two main ways to include Bootstrap in your project: by downloading the Bootstrap files and linking to them locally, or by linking to them from a CDN (Content Delivery Network).
To include Bootstrap by downloading the files and linking to them locally, you'll need to follow these steps:
- Go to the Bootstrap website and click the "Download" button.
- On the download page, you'll see several options for downloading Bootstrap. You can choose to download the compiled CSS and JavaScript files, or you can download the source files and compile them yourself.
- Once you've downloaded the files, you'll need to place them in your project's directory. You'll also need to link to them in your HTML file using the <link> and <script> tags. For example:
<!-- Link to the Bootstrap CSS file --> <link rel="stylesheet" href="path/to/bootstrap.css"> <!-- Link to the Bootstrap JavaScript file --> <script src="path/to/bootstrap.js"></script>
To include Bootstrap from a CDN, you can simply add the appropriate links to your HTML file. For example:
<!-- Link to the Bootstrap CSS file from the Bootstrap CDN --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> <!-- Link to the Bootstrap JavaScript file from the Bootstrap CDN --> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
Familiarize yourself with the grid system
The Bootstrap grid system is a key feature of the Bootstrap framework that allows you to create a responsive, mobile-first layout for your website or web application. It is based on a 12-column layout and allows you to create rows and columns to organize your content.
To use the grid system, you'll need to wrap your content in a container element and then create rows and columns using the .row and .col classes. The number of columns you use in a row should add up to 12, and you can specify the width of each column using the .col-* classes, where * is a number between 1 and 12. For example:
<div class="container">
<div class="row">
<div class="col-6">Column 1</div>
<div class="col-6">Column 2</div>
</div>
</div>This would create a row with two equal-width columns that take up half of the available width each.
You can also use the .offset-* classes to add spacing between columns, or the .order-* classes to change the order of columns on different screen sizes. For example:
<div class="container">
<div class="row">
<div class="col-6 offset-3 order-2">Column 1</div>
<div class="col-3 order-1">Column 2</div>
</div>
</div>This would create a row with two columns, where the first column is offset by 3 columns and appears after the second column on medium and large screens, but before it on small screens.
Use pre-designed Bootstrap components
Bootstrap provides a variety of pre-designed components that you can easily add to your project to add functionality and improve the user experience. These components include things like navbars, buttons, forms, and more, and they are fully customizable to fit your needs.
To use a pre-designed Bootstrap component, you'll need to include the Bootstrap CSS and JavaScript files in your project (as described in the previous articles), and then add the appropriate HTML code to your project. The HTML code for each component can be found in the Bootstrap documentation.
For example, to add a navbar to your project, you can use the following HTML code:
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">My Website</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Contact</a>
</li>
</ul>
</div>
</nav>This will create a navbar with a brand logo and a dropdown menu that appears when the screen size is small.
You can customize the appearance and behavior of each component by using the appropriate classes and attributes. For example, you can use the .navbar-light and .bg-light classes to give the navbar a light color scheme, or you can use the .nav-item and .nav-link classes to style the menu items.
Customize Bootstrap with your own CSS
While Bootstrap provides a lot of useful features, you may want to customize it to better fit your project's design. If you do not have access to Bootstrap's Sass variables, you can do this by using your own CSS to override the default Bootstrap styles.
To customize Bootstrap with your own CSS, you'll need to include the Bootstrap CSS files in your project, and then create a separate CSS file to hold your custom styles. You can then link to this file in your HTML file using the <link> tag.
For example, to create a custom stylesheet called "custom.css", you can use the following HTML code:
<!-- Link to the Bootstrap CSS file --> <link rel="stylesheet" href="path/to/bootstrap.css"> <!-- Link to the custom CSS file --> <link rel="stylesheet" href="path/to/custom.css">
In your custom CSS file, you can then use the !important declaration to override the default Bootstrap styles. For example, to change the color of all links to red, you can use the following CSS code:
a {
color: red !important;
}Keep in mind that when you override the default Bootstrap styles, you may need to adjust your styles to account for responsive design and other features of the framework. A better approach (but one which requires more advanced setup) is to customize Bootstrap's Sass variables.
Use Bootstrap's responsive design features
One of the key benefits of Bootstrap is that it is responsive, meaning it automatically adjusts to fit the screen size of the device it is being viewed on. You can use Bootstrap's responsive design features to ensure that your website or application looks great on all devices.
Bootstrap uses a combination of CSS media queries and grid system classes to achieve responsive design. The grid system is based on a 12-column layout and allows you to create rows and columns to organize your content. You can use the .col-* classes to specify the width of each column, where * is a number between 1 and 12. For example:
<div class="container">
<div class="row">
<div class="col-6 col-md-3">Column 1</div>
<div class="col-6 col-md-9">Column 2</div>
</div>
</div>This would create a row with two columns, where the first column takes up half of the available width on small screens, and one-third on medium screens and up. The second column takes up the remaining width on small screens, and two-thirds on medium screens and up.
Use Bootstrap's JavaScript components
One of the key features of Bootstrap is the ability to use its JavaScript components to enhance the user experience and add interactivity to your web pages.
To use Bootstrap's JavaScript components, you will need to include the Bootstrap JavaScript library in your HTML file, along with the necessary dependencies. You can do this by adding the following script tag to your HTML file:
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.3/js/bootstrap.bundle.min.js"></script>
You can then use the various Bootstrap JavaScript components by adding the appropriate data attributes to your HTML elements. For example, to create a modal dialog box, you can use the following code:
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
Open Modal
</button>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="myModalLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>There are many other Bootstrap JavaScript components that you can use, such as tabs, carousels, and dropdowns. You can find more information about these components and how to use them in the Bootstrap documentation.
Take advantage of Bootstrap's documentation
The Bootstrap documentation is a comprehensive guide to the framework and its features. It includes detailed instructions on how to use the various Bootstrap components and includes examples and code snippets to help you get started.

Use a Bootstrap starter template
A Bootstrap starter template is a pre-designed HTML file that includes the basic structure and elements of a website or web application, as well as the necessary CSS and JavaScript files for using Bootstrap. Using a Bootstrap starter template can be a helpful way to get started with a new project, as it provides a solid foundation and a basic layout that you can build upon.
There are many different Bootstrap starter templates available online, and you can choose one that best fits your needs and goals. Some starter templates are simple and minimalistic, while others are more complex and feature-rich.
To use a Bootstrap starter template, you will need to download the template file and extract the contents to your local development environment. The template will typically include the following files and directories:
- index.html: The main HTML file that contains the structure and content of the website or web application.
- css/: A directory that contains the necessary CSS files for styling the website or web application, including the Bootstrap CSS file.
- js/: A directory that contains the necessary JavaScript files for adding interactivity to the website or web application, including the Bootstrap JavaScript file.
- img/: A directory that contains any images used on the website or web application.
Once you have downloaded and extracted the starter template, you can begin customizing it to fit your specific needs. This might involve modifying the HTML structure, adding or removing content, changing the styling, or adding additional functionality.
To start working with the starter template, you will need to open the index.html file in a text editor or web development environment and begin making your changes. As you work, you can use the Bootstrap documentation as a reference to learn about the various components and features available to you.
Learn about Bootstrap's customisation options
There are many different customization options available with Bootstrap, and you can choose the ones that best fit your needs. Some of the key customization options include:
- Sass variables: Bootstrap is built with Sass, a popular CSS preprocessor. By modifying the Sass variables used in the Bootstrap source files, you can change the default values for things like colors, fonts, and layout settings.
- Custom build: Instead of using the pre-compiled Bootstrap CSS and JavaScript files, you can create a custom build by selecting the specific components and features you want to include in your project. This can help reduce the file size of your project and make it more efficient.
- Custom styles: You can add your own custom styles to your project by creating a separate CSS file and linking to it in your HTML. This allows you to override the default Bootstrap styles and create a unique look and feel for your project.
- Overriding class names: You can override the default Bootstrap class names by using your own custom class names in your HTML. This can be useful if you want to use multiple instances of the same component on a single page and need to differentiate between them.
By taking advantage of these customization options, you can create a unique and custom look and feel for your project, while still taking advantage of the power and convenience of the Bootstrap framework.
