VisualFox-FX 是一个 GWT 的动画和可视效果库，使用 CSS3 实现。主要特性：

• 支持javascript 和 css3 两种风格的动画
• Support hybrid mode (mixing javascript and css3 style animation)
• Use the concept of channel which provide an extra layer of flexibility (daisy chain your animation)
• Works directly with Element instead of Widget for additional flexibility
• 支持所有浏览器
• The javascript and hybrid mode are based on the GWT's Animation class
• Pre-built effects like fade in, fade out and reveal
• Simple

示例代码：

FXFade.range(DOM.getElementById("fox")).animate(2000);    //with call back  FXFade.range(DOM.getElementById("fox")).animate(2000).callback(new Command() {              @Override              public void execute() {                  System.out.println("Callback: effect ended");              }           });
