Embarking on the GSAP journey

I'm attempting my first animation using GSAP, but no matter what I try, nothing seems to be working. I've even tried using example code without success.

Within my PHP file, I have the following code snippet:

<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<style>
  #green {
    width: 100px;
    height: 100px;
    background-color: #0D9C02;  
  }
</style>
</head>
<body>
<div id="green"></div>
<script type="text/javascript" src="js/greensock/plugins/CSSPlugin.min.js"></script>
<script type="text/javascript" src="js/greensock/TweenLite.min.js"></script>
<script>
  $(document).ready(function(){
    var logo = document.getElementById("green");
    TweenLite.to(logo, 1, {left:"600px"});
  });
</script>
</body>

Despite following this setup, all that displays is a static green square. It's clear I must be overlooking something crucial - any insights on what that could be would be greatly appreciated. Thank you.

Answer №1

Quick fix: position: relative; was necessary in the style sheet for it to function properly.

Answer №2

position attribute is not present in the CSS code.

By default, HTML elements are positioned as static. If an element has a position: static property, the left property will have no impact.

Answer №3

To start, it's important to establish a TimeLine where you can link your tweens. You have the option of utilizing either TimelineLite or TimelineMax, each with its own subtle variations.

Here is an example code snippet to guide you-

<head>
<script src="https://cdn.flashtalking.com/frameworks/js/gsap/1.18.0/TimelineLite.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<style>
  #green {
    width: 100px;
    height: 100px;
    background-color: #0D9C02;  
  }
</style>
</head>
<body>
<div id="green"></div>
<script type="text/javascript" src="js/greensock/plugins/CSSPlugin.min.js"></script>
<script type="text/javascript" src="js/greensock/TweenLite.min.js"></script>
<script>
  $(document).ready(function(){
    theTimeline = new TimelineLite();
    var logo = document.getElementById("green");
    theTimeline.add(new TweenLite.to(logo, 1, {left:"600px"}));
  });
</script>
</body>

Answer №4

To achieve movement using tweening on the left value of an element, it is essential for the element to have a position value of either relative, absolute or fixed. Additionally, I recommend animating the x property instead of the left property as it utilizes transform, resulting in better performance.
