Once you've included GSAP, you're ready to create your first animation.

A Simple GSAP Animation

As a review, let's create an animation of a simple box moving across the screen. Suppose you have an HTML element with the class .box:

<div class="box"></div>

And some basic CSS to give it size and color:

.box {
    width: 100px;
    height: 100px;
    background-color: blue;
    position: relative;
}

Now, let's animate this box using GSAP:

gsap.to(".box", {duration: 2, x: 300});

In this line of code, gsap.to() is the method we use to create the animation. We're targeting .box, and we're telling GSAP to animate it over 2 seconds (duration: 2), moving it 300 pixels along the x-axis (x: 300).

Complete HTML code:

  <title>GSAP Animation Demo</title>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.10.3/gsap.min.js"></script>
  <style>
    .box {
      width: 100px;
      height: 100px;
      background-color: blue;
      position: relative;
    }
  </style>
</head>
<body>

  <div class="box"></div>

  <script>
    gsap.to(".box", {
      duration: 2,
      x: 300
    });
  </script>

</body>
</html>

Code Explanation:

  1. HTML Structure:
    • The <div class="box"></div> element creates a blue box that will be animated.
  2. CSS Styling:
    • The .box class styles the box with:
      • Width: 100px
      • Height: 100px
      • Background color: blue
      • Position: relative (allows for relative positioning)
  3. GSAP Inclusion:
    • The script tag in the <head> includes the GSAP library.
  4. GSAP Animation:
    • The gsap.to(".box", { ... }) code animates the box's horizontal position to 300 pixels over 2 seconds.

Key Points:

  • The box will move 300 pixels to the right over 2 seconds when the page loads.
  • You can customize the animation properties (e.g., duration, easing, starting position) to create different effects.
  • Consider adding more elements and animations to build more dynamic and engaging webpages.
