Hi guys, in this short tutorial, you're going to learn how to create an animated custom cursor with GSAP and basic HTML and CSS. Ok, then, what's this GSAP called?

What is GSAP ?

Detailed information

Ok.let's start the coding then.

index.html

<!DOCTYPE html>
<html lang="en" >
<head>
  <meta charset="UTF-8">
  <title>Custom Cursor</title>
  <link href="style.css" rel="stylesheet">
</head>
<body>

<div class="cursor"></div>
<div class="follower"></div>

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.3.4/gsap.min.js"></script>
<script src="main.js"></script>
</body>
</html>

The first thing you need to do is, add gsap.min.js to your index.html.To Install GSAP, you can use the following methods.

after that, import style.css and main.js to your index.html.

style.css


*{cursor: none;}

body{
  background-color:black;
  overflow: hidden;
}

.cursor{
    position: fixed;
    top: 0;
    left: 0;
    width: 20px;
    height: 20px;
    border-radius: 50%;
    background-color: #fff;
    z-index: 2000;
    user-select: none;
    pointer-events: none;
}

.follower{
    position: fixed;
    top: 0;
    left: 0;
    width: 100px;
    height: 100px;
    background-color: #6eff00;
    border-radius: 50%;
    opacity: 0.7;
    user-select: none;
    pointer-events: none;
}

main.js

gsap.set('.follower',{xPercent:-50,yPercent:-50});
gsap.set('.cursor',{xPercent:-50,yPercent:-50});

var follow = document.querySelector('.follower');
var cur = document.querySelector('.cursor');

window.addEventListener('mousemove',e => {
    gsap.to(cur,0.2,{x:e.clientX,y:e.clientY});
    gsap.to(follow,0.9,{x:e.clientX,y:e.clientY});
});

gsap.set('.follower',{xPercent:-50,yPercent:-50});
gsap.set('.cursor',{xPercent:-50,yPercent:-50});

Here, the gsap.set() methods always set the follower and the cursor centered on each other when we move the cursor.
Watch the Demo, then you can understand it clearly.

 gsap.to(cur,0.2,{x:e.clientX,y:e.clientY});

gsap.to() specifies the values to which the object is to be animated. Here,0.2 is the duration time of the cursor moves.

The 'clientX' property returns the horizontal mouse pointer coordinate when the mouse event is triggered.

The 'clientY' property returns the vertical mouse pointer coordinate when the mouse event is triggered.

Residential solar panels come in a variety of sizes and configurations, depending on the needs of the homeowner. Some homeowners may opt for rooftop installation, while others may choose a ground-mounted system. I would recommend this industrial solar panels Charlottesville to buy industrial solar panels at very cheap prices. The size of the system will depend on factors such as the homeowner's energy needs, the available space for installation, and the budget. One of the benefits of residential solar panels is that they are low maintenance.

Here's a quick tutorial on how to change the background color of a website dynamically by choosing a color from the custom color picker. The main idea is to use CSS variables to store and change the background color.
Highlights: rice purity test

Use Google Fonts fonts to decorate the website
Simple HTML structure with 4 main divs
Use the :root CSS variable to define the default background color
Use JavaScript to listen to the input event of the color input and update the CSS variable value accordingly
