Atomic Design: A Guide to Building Modular and Scalable Websites

At b13, we’ve embraced Atomic Design as a cornerstone of our process, harnessing its power to create websites that are as beautiful as they are functional, as scalable as they are consistent. Through this practice, we’ve been able to build websites that can grow with our clients’ needs, maintaining a coherent design language throughout.

In this blog post, we will explore Atomic Design, diving into its core principles and discussing how it can streamline web development. We’ll also share practical implementation tips and address some common challenges.

Join us on this journey through the atomic world of design, and discover how this method can revolutionize your web development process.

Introduction to Atomic Design

Atomic Design, a concept introduced by Brad Frost, is an innovative approach to web design and development that mirrors the hierarchical structure of matter. The method is named after the fundamental units of matter (atoms) but it extends to the composite elements (molecules, organisms, templates, and pages) that make up a complete web design system.

The five stages of Atomic Design are:

• Atoms: The simplest and most basic building blocks of a design system. They are the raw HTML elements such as a form label, an input, or a button.
• Molecules: Composed of several atoms combined together to perform a specific function, such as a search form that consists of a label, input field, and a button.
• Organisms: These are relatively complex components that consist of groups of molecules functioning together as a part of the interface — for instance, a site header that includes a logo, main navigation, and a search form. At b13, we refer to these as “content elements”.
• Templates: This stage involves laying out the design structure. It is where organisms are placed into context and the design begins to take shape.
• Pages: These are specific instances of templates filled with actual content. Pages depict a design’s final form, showcasing how the UI will look with real-world data.

At b13, we’ve integrated these principles of Atomic Design into our approach to web development. We build our design systems from the ground up, starting with the smallest elements — the atoms — and gradually combine them to form complex, well-structured websites. This systematic approach allows us to create reusable components, promoting consistency and efficiency in our designs.

Creating a Single Source of Truth (SSOT) for Atomic Design

Creating a Single Source of Truth (SSOT) is a fundamental step in Atomic Design. The SSOT serves as the central repository of all design elements, ensuring consistency and accuracy across the entire design system.

The first stage in creating an SSOT involves defining the global elements: the atoms. This includes universal aspects such as typography, color palette, grid system, and spacing rules — for example, that H1 text is bold and large. This definition of an H1 then would be universal throughout the entire project, as it would be inherited by other elements further up in the Atomic Design hierarchy (the molecules, organisms, templates, and pages).

At b13, we work mainly with Figma and cloud-based design. This allows us to build an Atomic Design system efficiently, linking design files, reusing elements at any level of the hierarchy, connecting libraries, and adding documentation and external links. This network of design files provides consistency and scales easily as a website grows and expands.

At the beginning of a project, we first create a file to define all of the atoms — this will be our Single Source of Truth. We begin with the basics, defining the main color, supporting colors, and the font. Building on that, we declare headlines, links, and buttons. These are styles that are going to be consistent throughout the website, and could even provide universal definitions across multiple websites of the same client. 

We then create one primary component for each defined element. Each time we use or reuse that component, a new instance is created. All changes made to the primary component will be inherited by its instances.

For example, we define a button as a component and make it blue. After placing it in ten different places on three different pages, we decide the button actually needs to be red. Instead of changing every button manually, we simply change the primary component and all other instances of it instantly inherit the change. You can immediately understand how this can save you time and hassle: When you are 500 (or 10,000) pages into building your site, with an SSOT, you can make one change that will update all the buttons. Without that central definition, you’d need to make 500 individual changes.

Streamlining Web Development with Atomic Design

After defining the basic atoms, at b13 we create a new file for every new feature or page. This practice of having separate files for different features or pages facilitates easy navigation, keeps our workspace tidy, and makes future updates simpler to manage.

We start with global elements that are going to be reused across the entire website. We create a file for navigation, for example, which will be used on every page of the website. The navigation will inherit the basic elements we’ve already defined, such as color and font.

If we then change those basic elements in the original file — the SSOT — they’ll be changed in the navigation as well. We will use this same concept for all of the additional files for other pages and features. Each will inherit the characteristics of the elements in our SSOT file.

This inheritance-based approach helps to ensure that we avoid mistakes and inconsistency. As Atomic Design’s creator, Brad Frost, writes: “Atomic Design gives us the ability to traverse from abstract to concrete. Because of this, we can create systems that promote consistency and scalability while simultaneously showing things in their final context. And by assembling rather than deconstructing, we’re crafting a system right out of the gate instead of cherry picking patterns after the fact.”

Atomic Design also saves us time and effort when creating design variants. For example, let’s say we design a teaser element for a homepage. If we also want teasers on another kind of content page, we can import the teaser element into the file for our new page type. Hey, presto — it’s identical! But if we want the teasers on the new content pages smaller, we can change the design atom (or molecule) for the new page type. The initial component, however, won’t be altered. The teaser on the homepage will remain in its original format. And the new pages will inherit and reproduce all of the main design, except the properties overridden in their specific design file.

We can now save our alterations of the teaser as a new state of the original component in Figma. It now has two different appearances that can be used as needed throughout the project — it’s become part of our design library.

Growing Your Library of Elements and Scaling Design

The ability to grow and scale design elements efficiently is one of the key advantages of Atomic Design, and it plays a crucial role in our workflow at b13. As a project expands, we create files for new pages and design new elements within those files. In this way, our library of elements expands. At some point in the process, we may be able to rely completely on the library of elements we have created. This reduces our workload and lets us create new features and pages faster and with less effort, recombining our comprehensive library of design components.

With global design atoms and components that can be imported into new files, we can expand that system with basically no limitations. Every new feature will have its own design file. We will not have to struggle with confusing design files that are very large and overly complicated.

If we add a new feature — even a year or two after the site redesign is launched — it will be easy to ensure the new feature is based on the same design principles as the rest of the project by simply importing the existing design tokens and elements.

This makes the whole process highly scalable.

Benefits of Atomic Design in Web Development

The application of Atomic Design principles in web development brings a range of benefits that enhance both the user experience and the productivity of design and development teams:

• Consistency and reusability for enhanced user experience: Firstly, Atomic Design allows for consistency across all aspects of a website. By constructing interfaces with reusable components, we ensure a cohesive user experience. Consistency translates into familiarity for users, leading to better engagement and ease of use.
• Improved workflow and productivity through modular design: Atomic Design promotes a modular approach to web design, which significantly improves workflow and productivity. Designers and developers can work on individual components or modules without disrupting the whole system. This modular nature makes it easier to test, iterate, and maintain the design system, reducing the complexity of web projects.
• Scalability and flexibility to accommodate future growth: Atomic Design’s component-based architecture enables scalability and flexibility. This is crucial for long-term web projects that need to grow and evolve over time. New features can be added seamlessly without disrupting the established design system, and existing elements can be quickly adapted as needs change.

Best Practices for Implementing Atomic Design

Adopting Atomic Design methodology is about more than just understanding its theoretical concepts. It involves a shift in perspective and requires specific practices that make it a successful approach for real-world web development. Here are some key best practices:

• Embrace a “design system first” approach: Instead of designing pages in isolation, think of each element as part of a larger, interconnected system. This mindset shift can help your team to better understand and apply the principles of Atomic Design.
• Redefine what “done” means: Atomic Design requires an evolution in how you define a project’s completion. Rather than considering a project “done” when the site goes live, embrace the idea that projects can and should continue to evolve and expand. This mindset fosters an environment of continuous improvement, allowing your design system to mature and grow over time.
• Encourage in-browser iteration: While design tools can help conceptualize and plan, the unique behavior of web interfaces often requires in-browser testing and iteration. This approach can lead to better responsive designs and encourages a closer working relationship between designers and developers.
• Create a maintainable system for all makers: A successful Atomic Design implementation is one that caters to all individuals involved in the process, including visual designers, product managers, UX designers, QA analysts, and frontend developers. Establishing a cross-disciplinary team can ensure that the design system is adaptable and meets the varied needs of each role. By involving all stakeholders, you can build a design system that’s not just consistent and scalable, but also robust, usable, and maintainable in the long run.

Challenges and Pitfalls in Atomic Design and How to Overcome Them

Atomic Design, while powerful, is not without its challenges. One of the most common issues faced by designers is the initial time investment. Establishing a robust design system requires careful thought, planning, and execution. However, this upfront investment ultimately results in significant time savings in the long run, as components can be reused and repurposed across projects.

Partly as a result of the time investment required, getting buy-in from all stakeholders can also be a challenge. Designers, developers, and product managers all need to understand the benefits of Atomic Design and be committed to its implementation. To achieve this, regular training and communication can be beneficial, along with showcasing the tangible benefits of Atomic Design such as increased productivity, consistency, and scalability. Indeed, Brad Frost dedicates an entire chapter in his Atomic Design book to this issue.

One powerful method Frost suggests for gaining this critical buy-in is through an exercise he calls an “interface inventory”. This involves cataloging every component used in your project — from typography and colors to buttons, form elements, and more — to expose the chaos of an unmanaged system. The process can be enlightening and, as Frost bluntly puts it, “Sometimes you need to make them feel the pain.”

During this exercise, stakeholders can visually grasp the redundancy and lack of cohesion in the current design system. Observing a table filled with varying button styles or a montage of mismatched form elements can be a powerful motivator for a unified, consistent design system. This tangible demonstration of the need for an organized, atomic approach can help secure the buy-in needed to successfully transition to Atomic Design.

Conclusion: Embracing Atomic Design for Better Web Development

At b13, the positive impact of adopting Atomic Design is indisputable. The methodology has enriched our web development process, fostering a more systematic and scalable design approach. It facilitates consistent, reusable, and adaptable components, enhancing both the design and user experience. This approach saves time, reduces workload, and allows for efficient modifications and expansions, accommodating future growth with ease.
