CSS Converting React Inline Styles to CSS Rules

In this article, we will introduce how to convert inline styles in React components to

1. Analyze the inline style object in the component and extract each style property and value.
2. Create a new CSS rule set with selectors associated with the component’s class name.
3. Add each style property and value to the CSS rule set.

Let’s illustrate this process with an example. Suppose we have a Button component that uses inline styles to define the button’s background color, font size, and border style. We want to convert these style properties into CSS rules.

import React from 'react'; 

const Button = () => { 
const buttonStyle = { 
backgroundColor: 'blue', 
fontSize: '16px', 
border: '1px solid black' 
}; 

return <button style={buttonStyle}>Click me</button>; 
}; 

export default Button; 

Following the above steps, we can convert the inline styles of the Button component into CSS rules:

.buttonClass { 
background-color: blue; 
font-size: 16px; 
border: 1px solid black; 
} 

In the example above, we created a class called .buttonClass and add the button’s style properties and values ​​to the CSS rule set. Now, we can use this class selector to apply styles to the button.

We can place these CSS rules in a separate stylesheet file, such as styles.css:

/* styles.css */ 
.buttonClass { 
background-color: blue; 
font-size: 16px; 
border: 1px solid black; 
} 

Then, we import this stylesheet into our React component:

import React from 'react'; 
import './styles.css'; 

const Button = () => { 
return <button className="buttonClass">Click me</button>; 
}; 

export default Button; 

Now, we have successfully converted inline styles to CSS rules and apply styles to components.

In addition to the above steps, there are also tools and libraries that can help us automatically convert inline styles to CSS rules. For example, babel-plugin-transform-react-inline-css is a Babel plugin that converts inline styles to CSS rules during the build process.
