What are the advantages and disadvantages of using CSS3 animations or JS sprite animations instead of GD for animations?

Using CSS3 animations or JS sprite animations instead of GD for animations can offer advantages such as smoother performance, easier implementation, and better compatibility across different devices and browsers. However, they may also have disadvantages such as limited control over the animation process, potential performance issues on older devices, and the need for additional knowledge of CSS or JavaScript.

// Example PHP code snippet using CSS3 animations for animations

<html>
<head>
    <style>
        @keyframes example {
            0% {transform: translateX(0);}
            50% {transform: translateX(200px);}
            100% {transform: translateX(0);}
        }

        .box {
            width: 100px;
            height: 100px;
            background-color: red;
            animation: example 2s infinite;
        }
    </style>
</head>
<body>
    <div class="box"></div>
