Foundation vs Bulma

When it comes to front-end development, CSS frameworks are essential tools that help developers build responsive and attractive websites efficiently. Among the plethora of options available today, Foundation and Bulma stand out as popular choices. In this article, we will delve deep into a comparison between these two frameworks, exploring their features, ease of use, customization, and community support, to help you decide which framework best suits your project needs.

What is Foundation?

Foundation is a responsive front-end framework created by ZURB, a product design company. It’s known for being an advanced and professional toolkit that provides a robust grid system, pre-styled components, and powerful plugins built on jQuery.

What is Bulma?

Bulma is a modern CSS framework based on Flexbox. It’s admired for its simplicity and ease of use, with a focus on mobile-first design. Unlike Foundation, Bulma doesn’t depend on JavaScript, which means that all its components are purely CSS.

Grid System

Both Foundation and Bulma provide flexible grid systems, but they have different approaches and features.

Foundation Grid

Foundation’s grid system is a mobile-first, flexible grid that allows developers to quickly create complex layouts. It includes a standard 12-column grid, block grid for equal-width elements, and an XY grid for 2D layout control.

<div class="grid-container">
  <div class="grid-x grid-margin-x">
    <div class="cell small-6 medium-4 large-2">1</div>
    <div class="cell small-6 medium-4 large-2">2</div>
    <div class="cell small-6 medium-4 large-2">3</div>
    <!-- ... -->

Bulma Grid

Bulma’s grid is based on Flexbox, which makes it easier to align and distribute space among items in a container, even when their size is unknown. Bulma’s columns are responsive and work in a similar 12-column system.

<div class="columns">
  <div class="column is-one-third">1/3</div>
  <div class="column is-one-third">1/3</div>
  <div class="column is-one-third">1/3</div>

Components and Elements

Both frameworks offer a wide range of UI components, but they differ in their design and customization options.

Foundation Components

Foundation comes with a comprehensive set of UI components such as buttons, navigation, forms, and cards. These components are designed to be functional and are fully customizable through SCSS variables.

<button class="button">Default Button</button>
<button class="button success">Success Button</button>
<button class="button alert">Alert Button</button>

Bulma Elements

Bulma’s components are pure CSS and they are known for their modern look and feel. The framework provides a rich set of elements like buttons, tiles, and boxes that are easy to use and customize with CSS classes.

<button class="button is-primary">Primary Button</button>
<button class="button is-link">Link Button</button>
<button class="button is-info">Info Button</button>


Customizing these frameworks to fit the design needs of your project is crucial. Let’s see how Foundation and Bulma handle customization.

Customizing Foundation

Foundation allows deep customization through SCSS. Developers can change the global styles, such as colors and fonts, and the framework will apply these styles consistently across all components.

$primary-color: #ff4136;
$secondary-color: #2ecc40;
$alert-color: #ffdc00;
$success-color: #01ff70;

@import 'foundation';

Customizing Bulma

Bulma also uses SCSS for customization, but it’s designed to be more modular. You can import only the components you need and override variables before the import to customize the look and feel.

$primary: #8e44ad;
$link: #3498db;
$info: #00d1b2;
$success: #23d160;
$warning: #ffdd57;
$danger: #ff3860;

@import 'bulma';

Responsiveness and Mobile-First Design

With the increasing importance of mobile-friendly websites, both Foundation and Bulma emphasize responsive design. However, their approaches to achieving this are slightly different.

Foundation’s Mobile-First Approach

Foundation is designed to be mobile-first, meaning that styles are designed for small devices first and then scale up to larger screens with media queries. Its visibility classes make it easy to show or hide elements based on the device size.

<div class="small-12 medium-8 large-4 cell">
  <p>This element is responsive, adjusting to the device's screen size.</p>

Bulma’s Mobile-First Design

Bulma also adopts a mobile-first approach with a set of responsive helper classes. It provides a simple way to build a responsive website using the is-mobile, is-tablet, is-desktop, and other classes to control the layout based on the screen size.

<div class="is-mobile">
  <p>This content is optimized for mobile devices.</p>

JavaScript Integration

While CSS is at the heart of both frameworks, JavaScript plays a significant role in interactive components like modals, dropdowns, and tabs.

Foundation and JavaScript

Foundation includes a variety of JavaScript plugins that add dynamic functionality to components. It relies on jQuery for many of its interactive elements, which can be a pro or con depending on your project’s requirements.

<ul class="dropdown menu" data-dropdown-menu>
    <a href="#">Item 1</a>
    <ul class="menu">
      <li><a href="#">Sub-item 1</a></li>
      <!-- More sub-items -->
  <!-- More items -->

<script src=""></script>

Bulma and JavaScript

Bulma is a CSS-only framework, which means it doesn’t come with any JavaScript. However, this can be an advantage if you prefer to use vanilla JavaScript or integrate with modern JavaScript frameworks like React, Vue, or Angular without worrying about jQuery conflicts.

<div class="modal" id="myModal">
  <div class="modal-background"></div>
  <div class="modal-content">
    <!-- Any other Bulma elements you want -->
  <button class="modal-close is-large" aria-label="close"></button>

  document.addEventListener('DOMContentLoaded', () => {
    const modal = document.querySelector('#myModal');
    const modalClose = modal.querySelector('.modal-close');

    modalClose.addEventListener('click', () => {

Community and Support

The community and support around a framework can greatly influence its usability and longevity. Let’s look at the community support for Foundation and Bulma.

Foundation Community

Foundation has been around for a longer time and has a large community of developers. It offers professional support, training, and a forum where you can ask questions and share knowledge. The framework is also regularly updated, with contributions from developers around the world.

Bulma Community

Bulma has a growing community and is gaining popularity due to its simplicity and modern design. It has a dedicated Gitter chat for support and discussion, and it’s also open to contributions on GitHub. Although younger than Foundation, Bulma’s community is enthusiastic and supportive.


Both Foundation and Bulma are powerful CSS frameworks that offer unique benefits. Foundation is feature-rich with extensive JavaScript plugins, making it suitable for complex projects that require a high level of interactivity. Bulma, on the other hand, is perfect for developers who prefer a lightweight, CSS-only approach that’s easy to learn and integrate with modern JavaScript tools.

When choosing between Foundation and Bulma, consider your project’s requirements, your comfort with JavaScript, and your design needs. Both frameworks have extensive documentation and supportive communities, making them excellent choices for modern web development.

Before making a decision, it’s recommended to experiment with both frameworks to see which one aligns best with your workflow and preferences. Happy coding!
