How to animate the opacity of an element on mouse hover using jQuery


Use the jQuery animate() method

You can use the jQuery animate(), mouseenter() and mouseleave() methods in combination with the CSS opacity property to animate the opacity of an element on mouse hover.

Let's try out the following example to understand how it basically works:

<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8">
<title>jQuery Animate Opacity on Hover</title>
        padding: 0;
        list-style: none;
    ul li {
        float: left;        
        margin: 10px; 
    ul li a img{
        opacity: 0.3;
<script src=""></script>
                opacity: "1"
                opacity: "0.3"
        <li><a href="#"><img src="club.jpg" alt="Club Card"></a></li>
        <li><a href="#"><img src="diamond.jpg" alt="Diamond Card"></a></li>
        <li><a href="#"><img src="spade.jpg" alt="Spade Card"></a></li>
        <li><a href="#"><img src="heart.jpg" alt="Heart Card"></a></li>
