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:
HTML
<!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.
CSS
* { 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.
Javascript
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.
