    那是一款来自Doodle的创新意识文章,它是三个基于HTML5 Canvas的电吉他,当大家将鼠标滑过吉他的弦时,电吉他将会发生巧妙的鸣响,特别酷的是,你可以运用键盘来弹奏一首动听的乐章,极其常有力的HTML5。

    可能你见过HTML5图纸破碎动漫特效,完结的法则也挺简单的。但是你应该未有见过摄像也得以破碎重新整合,那一个HTML5动漫片正是运用Canvas的连带天性,完毕了点击鼠标让录制破碎重新整合的效劳。在摄像区域点击鼠标,就能够让该区域的摄像破碎,让后透过一段时间后,破碎的区域又足以组合还原,视觉效果非常的厉害。

    那是一款基于HTML5的枢纽图动漫,它和其余难点图分化之处在于,它播放的不光是图片,而是能够自定义调整的网页成分。它不光在图纸间切换有连接动漫效果,何况在切换时图片中的元素也将现身动漫效果,比如图中的文字移动、克服、重新整合等。那款HTML5动画图片播放器算得上是高档大气上等级次序。

      example usage:

          autoStart: false,
          elements: {
            "img": {delay: 10},
            "h2": {delay: 500},
            ".copy": {delay: 800},
            ".button": {delay: 1000}
          }
        });
    
      to go to a specific frame:
        $("#slider").tlrkSlider("go", position);
        "position" can have one of the following values:
        "next", "prev", "first", "last", "+1", "-1" or a numeric value
    
      to start/stop the automatic loop:
        $("#slider").tlrkSlider("start");
        $("#slider").tlrkSlider("stop");
    
      to change the delay between automatic transitions:
        $("#slider").tlrkSlider("option", "delayAnimation", 1000);
    
      to change any option:
        $("#slider").tlrkSlider("option", option_name, option_value);
    
      Changing the "elements" object is not tested.
    
      Changing the following options: "navigation", "navigationClass", "framesSelector", "autoStart" won't have any effect for now.
      They are used only during the initialization.
    
      $("#slider").data("tlrkSlider") will return the plugin instance and the methods/properties can be accessed from there.
    
      The plugin contructor defaults are accessable through TlrkSlider.defaults
    
      The function that actually sweep the elements in/out can be overriden from
        TlrkSlider.prototype._animationIn and TlrkSlider.prototype._animationOut

            $(this).animate({"backgroundPosition": pos + "% 0"}, PRLX_SPEED);
          });
