# Gradient Generator using Javascript

Hello Coders! Welcome to another JavaScript Blog. 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.

##HTML


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

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

</head>

<body>
  <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>
  <h4></h4>
  <script type="text/javascript" src="script.js"></script>
</body>

</html>


``` 

Here we have used <input> 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.

##CSS


```
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;
}
#gradient{
    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);
}
input{
    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 inpur tags and then assigns them to the gradient ID in HTML.  

##JS 


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

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

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

``` 

And that's it. You're done.
