Can We Use React Props in CSS?

Introduction to Using React Props in CSS

Using props in React is a well-known concept among many developers; however, how these props can be applied in CSS can be somewhat unclear. When you need to create dynamic styles, utilizing props is a very practical and popular approach among React developers. This allows you to change your styles based on the values of the props, enhancing the user experience.

Why Using Props in CSS is Important?

When working on a large project, our styles may need to be changed based on different data values. By using props, you can easily apply these changes and create more responsive styles. In other words, you can change various aspects of your styles such as color, size, or even the font based on the data you have at hand.

Methods of Using Props in CSS

You can use props in CSS in several different ways. One of the most common methods is to use libraries like styled-components or Emotion to apply styled components. These methods provide you with the ability to dynamically change your styles based on props.

Practical Example of Using React Props in CSS

Here’s a simple example of how to use styled-components to apply styles based on incoming props:

import React from 'react';
import styled from 'styled-components';

const Button = styled.button`
  background-color: ${props => props.primary ? 'blue' : 'gray'};
  color: white;
  padding: 10px 20px;
  border: none;
  border-radius: 5px;
`;

export default function App() {
  return (
    

      Primary Button
      Secondary Button
    
  );
}
  

Line-by-Line Code Explanation

import React from 'react';
This line imports the React library, which is necessary to create components.
import styled from 'styled-components';
This line imports the styled-components module, allowing us to create styled components.
const Button = styled.button
Defines a styled component for the button tag.
background-color: ${props => props.primary ? 'blue' : 'gray'};
This sets the button's background color based on whether the 'primary' prop is present; if it is, the color will be blue, otherwise gray.
color: white;
This sets the button text color to white.
padding: 10px 20px;
This defines the inner padding for the button.
border: none;
Removes the border from the button.
border-radius: 5px;
Rounds the corners of the button.
export default function App() {
This defines the main component and exports it as the default export.
return (
Returns the main component's rendered HTML.
<div>
Creates a wrapper div for the contents.
<Button primary>Primary Button</Button>
This renders a button with the 'primary' prop, making its background color blue.
<Button>Secondary Button</Button>
This renders another button without the 'primary' prop, which will render with a gray background.
</div>
Ends the wrapper div.
