Understanding Zero-Runtime CSS
Zero-Runtime CSS is a new concept in web development that is gaining popularity among developers. It is a technique that allows developers to write CSS in JavaScript, which means that CSS is generated dynamically at build time instead of being rendered at runtime. This approach has several benefits, including faster load times, smaller file sizes, and easier maintenance.
Concept of Zero-Runtime CSS
The concept of Zero-Runtime CSS is based on the idea of generating CSS code statically, rather than dynamically. This means that the CSS code is generated during the build process, rather than at runtime. This approach has several benefits, including faster load times, smaller file sizes, and easier maintenance. By generating CSS code statically, developers can eliminate the need for CSS processing at runtime, which can significantly improve website performance.

Implementing Zero-Runtime CSS with Vanilla Extract
Zero-Runtime CSS with Vanilla Extract is a powerful tool for building web applications with static CSS stylesheets. In this section, we will discuss how to implement Zero-Runtime CSS with Vanilla Extract in your web application.
Setting Up Vanilla Extract
Before we can start using Vanilla Extract, we need to set it up in our project. The first step is to install it using npm. Here’s the command to install Vanilla Extract:
npm install @vanilla-extract/css @vanilla-extract/webpack-plugin
Once installed, we need to configure our webpack configuration to use the Vanilla Extract webpack plugin. Here’s an example webpack configuration:
const { VanillaExtractPlugin } = require('@vanilla-extract/webpack-plugin');
module.exports = {
// ... other webpack configuration
plugins: [
// ... other webpack plugins
new VanillaExtractPlugin(),
],
};
With Vanilla Extract set up, we can start creating our styles.
Creating Styles with Vanilla Extract
To create styles with Vanilla Extract, we use a combination of TypeScript and CSS. We define our styles in TypeScript using CSS-in-JS syntax, and Vanilla Extract compiles them into static CSS stylesheets.
Here’s an example of how to define styles with Vanilla Extract:
import { style } from '@vanilla-extract/css';
export const button = style({
backgroundColor: 'blue',
color: 'white',
padding: '10px 20px',
borderRadius: '5px',
cursor: 'pointer',
});
In this example, we define a style called button with a blue background, white text, padding, border radius, and a pointer cursor. We can use this style in our HTML like this:
<button class="${button}">Click me</button>
When we compile our application with Vanilla Extract, it will generate a static CSS stylesheet with the styles defined in our TypeScript code.
With these simple steps, we can start using Vanilla Extract to create static CSS stylesheets for our web applications. By using static stylesheets, we can improve the performance of our web applications and reduce the amount of CSS code we need to write.
Best Practices and Tips
Efficient Use of Vanilla Extract
When using Vanilla Extract, there are a few best practices to follow to ensure efficient use and optimal performance:
- Minimize the size of your CSS files: Vanilla Extract generates CSS at build time, so the larger your CSS files are, the longer it will take to generate the styles. Consider splitting your CSS files into smaller, more manageable chunks to speed up the build process.
- Use constants for frequently used values: To avoid repetition and make your code more maintainable, use constants for frequently used values such as colors and font sizes. This will also make it easier to make global changes to your styles.
- Avoid using dynamic values: Vanilla Extract generates static CSS, so dynamic values such as
calc()orvar()are not supported. Instead, use static values wherever possible to ensure optimal performance.
Troubleshooting Common Issues
While Vanilla Extract is designed to be easy to use, there are a few common issues that you may encounter:
- CSS not being generated: If you’re not seeing any CSS being generated, make sure that your styles are being imported correctly and that you’re using the correct file extensions (
*.css.tsor*.css.tsx). - Styles not being applied: If your styles are not being applied, make sure that you’re importing them correctly and that you’re using the correct class names.
- Errors during build: If you’re encountering errors during the build process, make sure that you’re using the correct syntax and that your code is valid. Check the error messages for more information on what went wrong.
By following these best practices and troubleshooting tips, you can ensure that your Vanilla Extract code is efficient, performant, and error-free.
