How To Change Placeholder Color In ReactJS ? - Coding

In this article, we’ll explore two different approaches to changing the placeholder color in ReactJS.

To change the color of the placeholder text, the CSS ::placeholder pseudo-element is primarily utilized. This handy pseudo-element enables us to style the placeholder text within an input field.

Syntax

::placeholder {
    color: yourColorValue;
}

Prerequisites

Steps to Create React Application

Step 1: Create a react application by using this command

npx create-react-app placeholderApp

Step 2: After creating your project folder, i.e. placeholderApp, use the following command to navigate to it:

cd  placeholderApp

Project Structure

The project structure will look like this.

Approach 1: Using CSS Styling

In this approach, it sets the placeholder text color to crimson using an inline <style>;. The result is a centered input field with a green title and a crimson placeholder color.

Example: This example shows the use of the above-explaned approach.

Javascript

// App.js file 
  
import React from "react"; 
const App = () => { 
    const containerStyle = { 
        display: "flex", 
        flexDirection: "column", 
        alignItems: "center", 
        marginTop: "20px", 
    }; 
  
    const titleStyle = { 
        fontSize: "24px", 
        color: "green", 
    }; 
    const inputStyle = { 
        width: "250px", 
        height: "40px", 
        padding: "10px", 
        fontSize: "16px", 
        border: "2px solid green", 
        borderRadius: "15px", 
        outline: "none", 
    }; 
  
    return ( 
        <div style={containerStyle}> 
            <h2 style={titleStyle}>Geeksforgeeks</h2> 
            <input 
                type="text"
                placeholder="Enter your text here"
                style={inputStyle}/> 
                  
            {/* Styling for the placeholder color */} 
            <style> 
                {` 
                    ::placeholder { 
                        color: crimson; 
                    }` 
                } 
            </style> 
        </div> 
    ); 
}; 
  
export default App;

Steps to run:

To open the application, use the Terminal and enter the command listed below.

npm start

Approach 2: Using Conditional Rendering

In the approach for modifying the color of placeholder text in React, we use state to track a condition (for example, a button click). Based on this condition, they dynamically assign a CSS class to the input element, thereby altering the color of the placeholder text.

Example: This example shows the use of the above-explained approach.

Javascript

// App.js 
  
import React, { useState } from "react"; 
import "./App.css"; // Import your CSS file 
  
const App = () => { 
    const [isRed, setIsRed] = useState(false); 
  
    const togglePlaceholderColor = () => { 
        setIsRed(!isRed); 
    }; 
  
    return ( 
        <div className="container"> 
            <h2 className="heading">Geeksforgeeks</h2> 
            <input 
                type="text"
                placeholder="Enter your text here"
                className={`input ${ 
                    isRed ? "red-placeholder" : ""
                }`}/> 
                  
            <button 
                className="button"
                onClick={togglePlaceholderColor}> 
                Toggle Placeholder Color 
            </button> 
        </div> 
    ); 
}; 
  
export default App;

CSS

/* App.css file*/
  
.container { 
    display: flex; 
    flex-direction: column; 
    align-items: center; 
    margin-top: 20px; 
} 
  
.heading { 
    font-size: 34px; 
    color: green; 
} 
  
.input { 
    width: 250px; 
    height: 40px; 
    padding: 10px; 
    font-size: 16px; 
    color: #333; 
    border: 2px solid green; 
    border-radius: 15px; 
    outline: none; 
} 
  
.red-placeholder::placeholder { 
    color: red; 
} 
  
.button { 
    padding: 10px 20px; 
    font-size: 16px; 
    border: none; 
    border-radius: 5px; 
    outline: none; 
    cursor: pointer; 
    background-color: #0074d9; 
    color: #fff; 
    margin-top: 10px; 
} 
  
.red-button { 
      /* Red button color when condition is met */
    background-color: red;  
}
