Color flippers are an entertaining way to add a bit of life to a website or application. With the help of JavaScript, it is possible to create a color flipper that will change the background color of an element with a click of a button. In this article, we will guide you through the steps required to create a color flipper using JavaScript.
Step 1: HTML Markup
To create a color flipper, we first need an element to apply the color. In this example, we will use a div element with an id of colorFlipper. We will also create a button that will trigger the color flip. The HTML markup will look like this:
<!DOCTYPE html> <html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Color Flipper</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="colorFlipper">
<button onclick="changeColor()">
Flip Color
</button>
</div>
</body>
<script src="script.js"></script>
</html>
|
Step 2: CSS Styling: To style the div element, we need to add some CSS code. In this example, we will set the width and height of the div element to 100vw and give it a border of 1px solid black. We will also set the initial background color to white.
* { box-sizing: border-box;
margin: 0px;
padding: 0px;
} #colorFlipper { width: 100vw;
height: 100vh;
display: flex;
justify-content: center;
align-items: center;
border: 1px solid black;
background-color: white;
} button { height: 50px;
width: 200px;
background-color: black;
color: white;
border-radius: 50px;
outline: none;
font-size: 20px;
cursor: pointer;
} |
Step 3: JavaScript Function
Now it’s time to write the JavaScript code that will change the background color of the div element. We will define a function called changeColor() that will generate a random color and apply it to the div element. To generate a random color, we will use the Math.random() method to generate a number between 0 and 255 for each of the red, green, and blue color values. We will then concatenate these values into a string and apply it as the background color of the div element.
function changeColor() {
let red = Math.floor(Math.random() * 256);
let green = Math.floor(Math.random() * 256);
let blue = Math.floor(Math.random() * 256);
let color = "rgb(" + red + "," + green + "," + blue + ")";
document.getElementById("colorFlipper").style.backgroundColor = color;
} |
Step 4: Testing: Finally, we can test our color flipper by opening the HTML file in a web browser and clicking the “Flip Color” button. Each time the button is clicked, the background color of the div element will change to a random color.
Output:
Congratulations! You have successfully created a color flipper using JavaScript. You can customize the code by adding more elements and styling or adjusting the code to fit your specific needs.
