Do You Prefer CSS Modules or Tailwind for Frontend Development

As a frontend developer, you've likely come across two popular styling solutions: CSS Modules and Tailwind. CSS Modules allow you to write CSS in separate files, making it easier to manage and reuse code.

CSS Modules are great for large-scale applications, where a single CSS file can become overwhelming. In contrast, Tailwind is a utility-first CSS framework that provides a set of pre-defined classes for common styling tasks.

One key benefit of CSS Modules is their ability to prevent CSS name collisions, which can occur when multiple CSS files share the same class names. This makes CSS Modules a great choice for teams working on complex projects.

Tailwind, on the other hand, offers a more opinionated approach to styling, with a focus on providing a consistent design language throughout an application. This can be a significant time-saver for developers, as they don't need to worry about writing custom CSS from scratch.

Tailwind CSS is a great choice for quick prototyping and keeping design consistent, as seen in its adoption by big companies like GitHub and Netflix.

Its utility-first method offers a set of basic classes that can be mixed to create new styles, making building faster and keeping styles consistent across the site.

To decide between CSS Modules and Tailwind, consider your project's needs, such as the size and complexity of your codebase, the need for separate styles, and your team's preferences.

Tailwind CSS gets over 6,000,000 downloads every week on NPM, indicating its popularity and widespread adoption.

Consider the following factors when making your decision:

Remember, there's no single best choice for everyone, and what works best can change with each project.

I prefer using CSS Properties over configs, especially with tools like Open Props that allow for quick leverage of properties like smooth transition timing functions.

Playing around with Open Props has shown me the value of being able to use custom props in a more straightforward way, without having to map them in the tailwind.config.js file or use inline values with arbitrary names.

Doing it the other way, once or twice, is fine, but it gets annoying when you're using custom values often, which is why I'd rather use CSS Properties.

The author of the article has built a CSS-in-JS tool, and using custom props with Open Props has been a game-changer for them, allowing for more flexibility and creativity in their projects.

It's a unique way to build CSS, offering a set of basic classes that can be mixed to create new styles, making building faster and keeping styles consistent across the site.

Many developers love Tailwind CSS for its utility-first method, which is the main example of this approach in the market.

However, some developers worry about the utility-first approach leading to a lot of styles, like a "utility soup."

But, there are big benefits too, such as saving energy from inventing class names, less growth in CSS files, and safer changes as CSS classes in HTML are local.

Big companies like GitHub and Netflix use Tailwind CSS successfully, finding it great for quick prototyping and keeping design consistent.

Deciding between Tailwind CSS and CSS Modules should be based on your project's needs, considering factors like codebase size and complexity, the need for separate styles, and your team's preferences.

Ultimately, there's no single best choice for everyone, and what works best can change with each project.

Here are some factors to consider when choosing between Tailwind CSS and CSS Modules:

If your team is highly proficient in CSS and comfortable with modern CSS techniques, you might not need the additional abstraction that Tailwind provides.

For teams with extensive CSS expertise, sticking with traditional CSS can be a more practical choice, especially when it comes to maintaining and updating legacy projects.

Sticking with traditional CSS can also save time and resources that would be spent on refactoring existing codebases.

Here are some scenarios where sticking with traditional CSS might be more practical:

CSS Modules let each component have its own styles, keeping class names from clashing with other parts of your app.

With CSS Modules, you can mix styles dynamically, making it great for complex interfaces. This makes your code easier to maintain and understand.

CSS Modules keep your styles modular and encapsulated, avoiding name clashes and making your code easier to maintain.

Here are the benefits of using CSS Modules:

CSS Modules grow with your app, making it easy to add, change, or remove styles without affecting other parts of your code.

CSS Modules are a game-changer for developers, allowing each component to have its own styles, which are only for that component.

This means class names won't clash with other parts of your app, making it easier to manage complexity.

CSS Modules also let you mix styles dynamically, making it great for complex interfaces.

This feature is particularly useful when working on large-scale applications with many interconnected components.

Using CSS Modules offers a range of benefits that make it an attractive choice for developers.

Modular and encapsulated styles are a key advantage of CSS Modules, keeping your styles to their components and avoiding name clashes.

This makes your code easier to maintain, as you don't have to worry about styles interfering with each other.

Improved debugging is another benefit of CSS Modules, making it easier to understand how styles are applied.

This is especially useful when working on complex projects, where debugging can be a major challenge.

CSS Modules also work seamlessly with CSS-in-JS frameworks, offering a strong styling solution.

Some popular frameworks that work well with CSS Modules include Styled Components, Emotion, and others.

By using CSS Modules, you can build a scalable and extensible CSS structure that grows with your app.

This means you can add, change, or remove styles without affecting other parts of your code, making it easier to maintain and update your project.

Tailwind offers a unique utility-first approach to building CSS, providing a set of basic classes that can be mixed to create new styles. This method makes building faster and keeps styles consistent across the site.

Over 6,000,000 downloads every week on NPM show how popular Tailwind CSS has become. It's a favorite among developers who value its utility-first method.

The utility-first approach can lead to a "utility soup" of styles, but it also has big benefits: energy saved from inventing class names, less growth in CSS files, and safer changes as CSS classes in HTML are local.

Tailwind's utility-first method makes it easy to quickly prototype and build interfaces, offering a wide range of pre-defined utility classes that let developers style directly in the HTML, skipping the need for custom CSS.
