How to Convert CSS to JSX - Step by Step Guide

Step 1

Input Your CSS Rules

Let's convert your CSS to React inline styles! Whether you're building new components, migrating styles, or applying dynamic styling, you have several convenient options:

•
Paste directly: Copy your CSS rules from your stylesheet and paste them into the input editor
•
Upload a file: Click "Upload" to select a .css or .txt file from your computer
•
Try the sample: Click "Sample" to load example CSS and see how the converter works

Example: CSS Rules Input

Here's what standard CSS rules look like:

.card {
  background-color: #ffffff;
  border-radius: 8px;
  box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
  padding: 20px;
  margin-bottom: 16px;
  max-width: 400px;
}
Step 2

Automatic Conversion & Transformation

The magic happens instantly! As soon as you input CSS, the converter automatically:

•
Converts property names: Transforms kebab-case to camelCase (background-color → backgroundColor)
•
Handles values: Processes pixel values and other CSS units appropriately for React
•
Creates style objects: Generates JavaScript objects with proper variable names

Example: JSX Style Object Output

The same styles, now as React inline style objects:

const cardStyle = {
  backgroundColor: '#ffffff',
  borderRadius: '8px',
  boxShadow: '0 2px 4px rgba(0, 0, 0, 0.1)',
  padding: '20px',
  marginBottom: '16px',
  maxWidth: '400px'
};
Step 3

Review the JSX Style Objects

Check your converted styles! The output panel shows your style objects ready for React components:

•
Proper formatting: JavaScript objects are beautifully formatted with correct syntax
•
Syntax highlighting: Color-coded JavaScript makes it easy to read and understand
•
Usage example: Shows how to apply the styles in your React components
Step 4

Export Your JSX Styles

Get your JSX styles ready for your components! Multiple export options make it easy to integrate into your React project:

•
Copy to clipboard: One-click copying for quick pasting into your React component
•
Download as file: Save as a .js file for importing into your project
•
Real-time conversion: Changes update instantly as you edit your CSS

Frequently Asked Questions

What is CSS to JSX conversion?

CSS to JSX conversion transforms CSS rules into React inline style objects. This is useful when you want to apply styles dynamically in React components using the style prop instead of external CSS files.

How do I use the converted JSX styles in React components?

Simply copy the generated style objects into your React component file and apply them using the style prop. For example: <div style={cardStyle}>. The style objects are plain JavaScript objects that React understands.

Why are some CSS properties converted to camelCase?

React requires style properties to be written in camelCase instead of the kebab-case used in CSS. For example, background-color becomes backgroundColor. This is a requirement of the React inline style system.

Are pseudo-classes and media queries supported?

React inline styles don't support pseudo-classes (like :hover) or media queries. This converter focuses on converting standard CSS properties to inline styles. For advanced styling, consider using CSS Modules, styled-components, or other CSS-in-JS solutions.

What happens to pixel values in the conversion?

Pixel values (e.g., 20px) can be converted to numbers in React inline styles. However, the converter preserves the original string format to ensure compatibility. You can manually convert them to numbers if needed.

Is this tool free to use?

Yes, totally free with no limitations on usage frequency or features. No registration required, and you can convert unlimited CSS rules to JSX with full syntax highlighting and instant conversion.
