Tailwind CSS vs Emotion

In this developer-oriented guide, we'll get a comprehensive understanding of two popular style tools in use today: Tailwind CSS and Emotion JS. We'll discern what they are, and their respective use-cases in a project environment. Let's dive in.

What is Tailwind CSS?

Tailwind CSS is essentially a utility-first CSS framework that provides a set of pre-defined CSS classes you can leverage when styling your HTML elements. This makes it highly customizable and an excellent tool for quick prototyping and in building projects with recurring UI patterns. Another significant advantage is its small file size, making it suitable for performance-critical applications.

The following is a simple example of Tailwind CSS usage in styling an HTML button:

<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Button
</button>

Each class added to the button element equips it with a specific style, a clear testament to the “utility-first” approach employed by Tailwind CSS.

What is Emotion JS?

Emotion, on the other hand, is a robust library that allows for the composition and use of CSS in JavaScript. It stands out for its provision of fine-grained control over component styles, which makes it well-suited for performance-centric applications. Furthermore, it supports server-side rendering and has a strong supporting community and ecosystem.

As an example, the following is a snippet of how Emotion JS can be used to style a React component:

/** @jsx jsx */
import { jsx, css } from '@emotion/core'

const color = 'darkgreen'

function Button({ children }) {
  return (
    <div
      css={css`
        padding: 32px;
        background-color: hotpink;
        font-size: 24px;
        border-radius: 4px;
        color: ${color};
      `}>
      {children}
    </div>
  )
}

The css function from Emotion JS is used to write CSS in JavaScript, with both string and object styles possible.

How are Tailwind CSS and Emotion JS used in a project?

The choice between Tailwind CSS and Emotion JS boils down to developer preference and specific project requirements. If you prefer working with utility classes, Tailwind CSS is the way to go. On the other hand, Emotion JS is perfect for developers who favor writing CSS in JavaScript.

One intriguing solution some developers swear by is a combination of both Tailwind CSS and Emotion JS. An instance of this can be seen with Babel macros being utilized to integrate Tailwind's class names directly into Emotion's template literals, resulting in a seamless fusion that brings the best of both worlds.

All being said, the choice lies in the hands of the developer and the goals of the project at hand.

In the next section, we will delve deeper into these technologies, examining their respective strengths and weaknesses, and provide a comparative analysis to guide your choice in using either of them.

Please stay tuned.

This section will delve into the practical application of Tailwind CSS and Emotion JS in a real-world context. We will cover setting up and integrating these tools, building a prototype, and discussing a case study.

Setting Up and Integrating Tailwind CSS and Emotion JS

Implementing both Tailwind CSS and Emotion JS into your project initially may seem like a daunting task, but with the right approach, it can be quite straightforward. Here's a simplified setup:

Firstly initialize a new project directory and use npm to install both tailwindcss and @emotion/core packages.

mkdir tailwind-emotion
cd tailwind-emotion
npm init -y
npm install tailwindcss @emotion/core

Then configure Tailwind CSS and Emotion JS by creating a tailwind.config.js file and a .babelrc file respectively in your project's root directory.

For tailwind.config.js it may look something like this:

module.exports = {
  purge: ["./src/**/*.js"],
  theme: {
    extend: {},
  },
  variants: {},
  plugins: [],
}

And for .babelrc:

{
  "presets": ["@babel/preset-react"],
  "plugins": ["@emotion"]
}

Lastly import tailwind/base, tailwind/components, and tailwind/utilities in your App.js or main component file to bring in the Tailwind CSS styles and start using them.

Building with Tailwind CSS and Emotion JS

Once set up and integrated into your project, you can start building your user interface. You'll find that using Tailwind CSS and Emotion JS helps you to be efficient and swift in styling your components.

With Tailwind, you can benefit from several utility classes that are ready to be utilized as needed. For example, rather than writing raw CSS to center elements on the page, you can simply add flex justify-center items-center to your class. Meanwhile, in situations where there's a need for dynamic styling based on conditional factors or states, Emotion JS comes into play. Its powerful CSS-in-JS approach allows you to implement logic inside your styles.

/** @jsx jsx */
import { jsx } from '@emotion/core'

export default function Button({ isActive }) {
  return (
    <button
      css={{
        backgroundColor: isActive ? 'blue' : 'gray',
        ':hover': {
          backgroundColor: 'yellow'
        },
      }}
      className="py-2 px-4 text-white font-semibold rounded-lg shadow-md"
    >
      Click Me
    </button>
  )
}

The example above demonstrates how to make use of both tools. The layout and typography styles are handled by the Tailwind classes, whereas the dynamic background color switch is managed by Emotion.

Case Study: Dynamic Styles with Emotion JS and Tailwind CSS

A practical example of where Emotion JS and Tailwind CSS can work hand in hand is when creating a toggle switch. With Emotion JS, you're able to change the styles dynamically based on the state of the toggle, while the layout and other static styles can be efficiently handled with Tailwind's utility classes.

/** @jsx jsx */
import { jsx } from '@emotion/core'

export default function Switch({ isOn }) {
  return (
    <div 
      css={{
        backgroundColor: isOn ? 'green' : 'red'
      }}
      className="relative inline-block w-10 ml-2 transition-colors duration-200 ease-in-out cursor-pointer rounded-full"
    >
      <div className="absolute left-0 top-0 bottom-0 my-1 ml-1 transition-all duration-200 ease-in-out bg-white shadow-md rounded-full w-6 h-6"></div>
    </div>
  )
}

In this case, the background color of the switch is altered by Emotion JS, while Tailwind classes manage the overall layout and transition of the switch.

In conclusion, through a blend of Tailwind CSS for static and global style structures and Emotion JS for dynamic, component-specific styles, you can achieve a highly flexible, functional, and aesthetically appealing UI in your application.

Working with Emotion JS

Emotion JS is a performant and flexible CSS-in-JS library. It takes an all-in-one approach, allowing you to write both component-specific styles and global styles.

When defining styles in Emotion, opt for using the "css" prop over the "styled" API, especially for component-level styles. This helps to keep styles co-located with your JavaScript, improving readability and maintainability.

To minimize redundant or verbose styles, utilize Emotion's ability to nest styles akin to SASS. This decreases overall stylesheet size while making your code cleaner and less error-prone.

Working with Tailwind CSS

On the other hand, Tailwind CSS, a utility-first CSS framework, promotes smaller, reusable utility classes over component-specific styles.

A common error developers make when starting with Tailwind is following the traditional CSS approach and creating larger, monolithic classes. Instead, create small utility classes and use @apply directive to compose these classes into complex styles.

Using Tailwind's configuration file (tailwind.config.js), customize your project's color scheme, breakpoints, and typography to match your brand identity and design requirements. Remember, Tailwind is highly customizable, so use this to your advantage.

Combining Emotion JS and Tailwind CSS

Emotion JS and Tailwind CSS can be combined for a solid CSS architecture. Utilizing Tailwind’s utility classes, you create a set of base styles; then, use Emotion to write component-specific styles.

To integrate both, you can also make use of an amazing library, twin.macro. This allows applying Tailwind’s utility classes inside Emotion’s CSS prop or styled-components. It’s a marriage between writing traditional CSS and having utility classes.

Tips for common cases

As a developer, having a standard set of styles, handpicked from Tailwind’s utility classes and using Emotion for component-specific styles, can speed up your development process and ensure uniformity across your application.

Also, leverage the power of Emotion's theme provider to maintain a consistent design language across different components. This also becomes handy in dark mode implementation or multi-theming requirements.

In summary, knowing when to use Emotion JS or Tailwind CSS requires you to understand the unique strength of each, and their synergy can provide a robust styling solution for your applications.

// Bad 
const Button = styled.button`
padding: 8px 12px;
background-color: #673ab7;
color: #fff;
`;
<Button>Click me</Button>

// Good 
const Button = ({children}) => (
<button
    css={`
        padding: 8px 12px;
        background-color: #673ab7;
        color: #fff;
    `}
>
    {children}
</button>
);
<Button>Click me</Button>

Use Emotion’s "css" prop for component-level styles and Tailwind’s utility classes for standard application-wide styles.
