Cursor Effects and Animation with CSS and JS

Custom cursor effects and animation using css and javascript. Learn how to customize the mouse pointer and their events.

 Techmates   27 Jul, 2020  41

In this demo, we'll learn how to create custom cursor effects and animation with simple steps. The post contains 6 demos. 

The beautiful cursor and hover animation will change the look of your web page. In the latest trend, most of the side uses a custom animated cursor to emphasize the components like navigation, buttons, links, cat, etc… 

Let's create the Cursor/Pointer markup. 

Cursor HTML

<div id="cursor"><div id="circle"></div></div>

We've used simple div with cursor id and circle id then we will apply the CSS and JS events to these ids. 

And hide the system cursor

html, body { cursor: none; }

Then apply the CSS to cursor id #cursor

Common Cursor CSS

#cursor {
  position: absolute;
  width: 40px;
  height: 40px;
  top: 50%;
  left: 50%;
  border-radius: 100%;
  background: var(--purple);
  pointer-events: none;
  mix-blend-mode: difference;
  transition: transform .5s;
  z-index: 99;
}

That CSS style may vary according to the different demos.

Next, we will create the Javascript events for cursor move & hover animation.

Javascript

var a_link = document.querySelectorAll(".a-link");
// Handle mouse over/out event on links
a_link.forEach(e => e.addEventListener('mouseenter', handleMouseEnter));
a_link.forEach(e => e.addEventListener('mouseleave', handleMouseLeave));
window.addEventListener('mousemove', handleMouseMove);
// Move the cursor in dom/window
function handleMouseMove(event) {
  console.log(event);
  var top = event.pageY - (cursor.clientHeight / 2);
  var left = event.pageX - (cursor.clientWidth / 2);
  cursor.style.top = top + 'px';
  cursor.style.left = left + 'px';
}
// event: mouse enter on link
function handleMouseEnter() {
  cursor.classList.add('hovered');
}
// event: mouse leave on link
function handleMouseLeave() {
  cursor.classList.remove('hovered');
}

 

The page design

Next, we design the page & hover elements. 

We have a common HTML page structure for all demos. 

HTML Markup

<div id="cursor"><div id="circle"></div></div>
  <div class="box">
    <ul class="menu">
      <li><a href="#" class="a-link">Home</a></li>
      <li><a href="#" class="a-link">About</a></li>
      <li><a href="#" class="a-link">Services</a></li>
      <li><a href="#" class="a-link">Blog</a></li>
      <li><a href="#" class="a-link">Contact</a></li>
      <li class="right"><a href="#" class="a-link"><img src="assets/icons/user.svg"></a></li>
      <li class="right"><a href="#" class="a-link"><img src="assets/icons/search.svg"></a></li>
    </ul>

Demo 4

In deom4, we've slightly different HTML page(box) & element structure to represent the arrows. 

HTML

<div id="cursor"></div>
  <div class="box">
    <ul class="menu">
      <li><a href="#" class="a-link">Home</a></li>
