Bootstrap vs Foundation

When it comes to front-end development, CSS frameworks are foundational tools that help developers create responsive, mobile-first web designs. Among the myriad of frameworks available, Bootstrap and Foundation have emerged as two of the most popular choices. In this article, we will delve into an exhaustive comparison of Bootstrap and Foundation, examining their features, ease of use, community support, and more to help you decide which framework best suits your project’s needs.

Bootstrap: The Most Popular CSS Framework

Bootstrap is an open-source CSS framework developed by Twitter that has gained widespread popularity for its mobile-first approach and extensive features. It includes a comprehensive set of HTML, CSS, and JavaScript components that are pre-styled and ready to use, making it a go-to choice for developers looking to accelerate their workflow.

Key Features of Bootstrap

  • Responsive Grid System: Bootstrap’s grid system uses a series of containers, rows, and columns to layout and align content. It’s built with flexbox and is fully responsive.
  • Pre-styled Components: It offers a wide range of pre-styled components such as buttons, navigation bars, modals, and more.
  • JavaScript Plugins: Bootstrap comes with jQuery-based JavaScript plugins that add interactivity to components like dropdowns, carousels, and tooltips.
  • Customization: Developers can customize Bootstrap’s components using SASS variables and mixins or overriding the default styles.
  • Extensive Documentation: Bootstrap has thorough and beginner-friendly documentation, making it easy for developers to find the information they need.

Getting Started with Bootstrap

To start using Bootstrap, you can either download it from the Bootstrap download page or include it in your project via a CDN. Here is a quick example of how to include Bootstrap using a CDN:

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="">

<!-- Optional JavaScript; choose one of the two! -->

<!-- Option 1: Bootstrap Bundle with Popper -->
<script src=""></script>

Code Samples: Bootstrap vs Foundation

Let’s look at some code samples to illustrate the differences between Bootstrap and Foundation. We’ll start with the grid system, which is a fundamental aspect of both frameworks.

Bootstrap Grid Example

Bootstrap uses a 12-column grid system. Here’s a simple three-column layout:

<div class="container">
  <div class="row">
    <div class="col-md-4">Column 1</div>
    <div class="col-md-4">Column 2</div>
    <div class="col-md-4">Column 3</div>

Foundation Grid Example

Foundation’s XY Grid also uses a 12-column system. Here’s the equivalent three-column layout:

<div class="grid-container">
  <div class="grid-x grid-margin-x">
    <div class="cell medium-4">Column 1</div>
    <div class="cell medium-4">Column 2</div>
    <div class="cell medium-4">Column 3</div>

In these examples, both frameworks achieve a similar result, but the class names and structure differ slightly. It’s these nuances that can influence a developer’s choice between Bootstrap and Foundation.

Let me know when you’re ready for the second half of the article, where we will cover topics such as customizability, performance, and the community around each framework.

Customizability: Tailoring Your Framework

Both Bootstrap and Foundation offer extensive customizability, allowing developers to tailor the frameworks to their specific needs. This is crucial for maintaining a unique brand identity and avoiding the “cookie-cutter” look that can come from using default styles.

Bootstrap Customization

Bootstrap can be customized in several ways:

  • SASS Variables: Bootstrap’s SASS files include variables for colors, sizes, and more, which you can modify to change the look and feel of components.
  • Custom Builds: You can use Bootstrap’s build tools to create a custom version of the framework with only the components you need.
  • Overriding Styles: You can add your own CSS to override Bootstrap’s default styles.

Here’s an example of using SASS to customize Bootstrap’s primary color:

// Custom.scss
$theme-colors: (
  "primary": #007bff, // Custom primary color

@import "bootstrap";

Foundation Customization

Foundation also provides powerful customization options:

  • SASS Variables: Like Bootstrap, Foundation uses SASS variables for easy customization of its design tokens.
  • Modular Import: You can choose to import only the specific SCSS files for the components you plan to use.
  • Foundation Settings File: The _settings.scss file is where you can easily fine-tune the framework.

An example of customizing Foundation’s primary color:

// settings.scss
$primary-color: #1779ba; // Custom primary color

@import 'foundation';

Performance Considerations

Performance is a key factor when choosing a CSS framework. Both Bootstrap and Foundation are quite efficient, but the way you use them can affect your website’s performance.

  • File Size: Using custom builds and importing only necessary components can significantly reduce the file size, leading to faster page loads.
  • CSS & JavaScript Overhead: Be mindful of the CSS and JavaScript that both frameworks bring. If you’re not using certain features, it’s best to exclude them.

Community and Support

The strength of a framework’s community and the support it offers can be critical, especially when troubleshooting issues or looking for resources.

Bootstrap Community

Bootstrap has a massive community:

  • Extensive Plugins and Themes: There are countless third-party plugins and themes available for Bootstrap.
  • Active Development: Bootstrap is actively maintained, with regular updates and a clear roadmap.
  • Community Support: With its popularity, finding help on forums, Stack Overflow, or other community channels is usually straightforward.

Foundation Community

Foundation’s community is smaller but still active:

  • Professional Focus: Foundation tends to attract a community of professional developers and designers.
  • Training and Certification: ZURB offers training and certification for Foundation, which can be a valuable resource for teams.
  • Support Forums: Foundation has dedicated forums and an active presence on sites like Stack Overflow.


In the debate between Bootstrap and Foundation, the best choice depends on your project’s needs and your personal or team preferences. Bootstrap offers ease of use and a vast array of resources, making it ideal for getting projects off the ground quickly and for developers of all skill levels. Foundation, on the other hand, provides a more sophisticated toolset that might be preferred by advanced users who require a higher degree of customization and control.

Both frameworks are excellent choices and have proven themselves in the field. By considering factors such as customizability, performance, community, and support, you can make an informed decision that aligns with your development goals.

Remember, the best way to truly understand the nuances of each framework is to get your hands dirty and start building. Experiment with both Bootstrap and Foundation to see which one resonates with your workflow and project requirements. Happy coding!
