Welcome back to the Javascript project series. Today i'm share another amazing project.

Gradient Generator using Javascript.

  • In this, we're going to see how generate your own gradient with pure JavaScript. This can be considered as a mini-project if you're learning JavaScript. It teaches you DOM concepts and how to change styling of CSS through JavaScript.

Here's a preview :

That being said, let us get started.

  • Step - 1:- Like always, create 3 files - Index.html, Style.css and Script.js.

  • Step - 2:- Copy the below HTML code and paste it into your code editor.


<!DOCTYPE html>
<html lang="en">

  <meta charset="UTF-8">
  <title>Create Gradient using Javascript</title>
  <link rel="stylesheet" href="./style.css">


  <h3>Create Gradient using Javascript</b></h3>
  <div id="gradient"></div>
  <input class="color1" type="color" name="color1" value="#00ff00">
  <input class="color2" type="color" name="color2" value="#ff0000">
  <h2>Code for generated gradient is - </h2>
  <script type="text/javascript" src="script.js"></script>

  • Here we have used tag of type color to choose various colors for gradient. We have added a section for card with id=gradient to show the gradient on card.

  • Step - 3:- Below is the CSS code for styling.


body {
    font: 'Raleway', sans-serif;
    color: rgba(0,0,0,.5);
    text-align: center;
    font-family: Verdana, Geneva, Tahoma, sans-serif;
    height: 100vh;
    background-color: #f6f7fc;
    position: relative;
    background: linear-gradient(45deg, #00ff00 , #ff0000);
    width: 250px;
    height: 320px;
    border-radius: 25px;
    left: 50%;
    transform: translateX(-50%);
    margin-bottom: 50px;
    box-shadow: 2px 31px 35px -15px rgba(0,0,0,0.64);
    border-radius: 50%;
    height: 40px;
    width: 40px;
    border: none;
    outline: none;
    -webkit-appearance: none;
input::-webkit-color-swatch-wrapper {
    padding: 0; 
input::-webkit-color-swatch {
    border: none;
    border-radius: 50%;
h3 {
    font: 600 1.5em 'Raleway', sans-serif;
    color: rgba(0,0,0,.5);
    text-align: center;
    text-transform: uppercase;
    letter-spacing: .3em;
    width: 100%;
  • Step - 4:- Below is the JavaScript code which is the most important part in this Generator. We declared some variable to store the DOM objects of a tag. We then declared a function called "setGradient()" which gets the color code from input tags and then assigns them to the gradient ID in HTML.


var css = document.querySelector("h4");
var color1 = document.querySelector(".color1");
var color2 = document.querySelector(".color2");
var gradient = document.getElementById("gradient");

function setGradient() { = 
 "linear-gradient(45deg, " 
 + color1.value 
 + ", " 
 + color2.value 
 + ")";
 css.textContent = + ";";

color1.addEventListener("input", setGradient);
color2.addEventListener("input", setGradient);

And that's it. You're done.
