令人惊叹的HTML5动画及源码分析下载

HTML5非常酷，利用HTML5制作动画简直让我们忘记了这世界上还有flash的存在。今天我们要分享的一些HTML5动画都还不错，有些动画设计还是挺别出心裁的。另外，每一款HTML5动画都提供源代码下载，并且我们对源码作一些简单的分析。

HTML5画图特效 超酷的笔刷动画

这是一款基于HTML5的画笔动画，可以选择不同的笔刷形状，笔刷在画布上移动时就会播放非常绚丽的动画效果。

核心jQuery代码：

var H = 0;

$('.button').bind('mousedown touchstart',function(e) {
  $('.clicked').removeClass('clicked');
  $(this).addClass('clicked');
});

$(document).bind('mousemove touchmove',function(e) {
    e.preventDefault();
    var drawSize = 55;
    var drawType = $('.clicked').html();
    var floatTypes = Array('floatOne','floatTwo','floatThree','floatFour','floatFive');
    var floatType = floatTypes[Math.floor(Math.random()*floatTypes.length)];
    var xPos = e.originalEvent.pageX;
    var yPos = e.originalEvent.pageY;

    $('body').append('<div class="draw" style="font-size:'+drawSize+'px;left:'+xPos+'px;top:'+yPos+'px;-webkit-animation:'+floatType+' .9s 1;-moz-animation:'+floatType+' .9s 1;color:hsla('+H+',100%,70%,1)">'+drawType+'</div>');

    $('.draw').each(function() {
      var div = $(this);
      setTimeout(function() {$(div).remove();},800);
    });
});

setInterval(function() {
  if(H<=360) {H++;}
  else {H=0;}
},10);

HTML5可爱的404页面动画 很逗的机器人

利用HTML5绘制的机器人，还会动哦。你可以将它作为一个富有创意的404页面。

核心CSS3代码：

@-webkit-keyframes move {
  0%, 100% {
    -webkit-transform: rotate(0deg) translate3d(0px, 0px, 0px);
    transform: rotate(0deg) translate3d(0px, 0px, 0px);
  }

  25% {
    -webkit-transform: rotate(5deg) translate3d(5px, 5px, 0px);
    transform: rotate(5deg) translate3d(5px, 5px, 0px);
  }

  75% {
    -webkit-transform: rotate(-6deg) translate3d(-5px, 5px, 0px);
    transform: rotate(-6deg) translate3d(-5px, 5px, 0px);
  }
}

@keyframes move {
  0%, 100% {
    -webkit-transform: rotate(0deg) translate3d(0px, 0px, 0px);
    transform: rotate(0deg) translate3d(0px, 0px, 0px);
  }

  25% {
    -webkit-transform: rotate(5deg) translate3d(5px, 5px, 0px);
    transform: rotate(5deg) translate3d(5px, 5px, 0px);
  }

  75% {
    -webkit-transform: rotate(-6deg) translate3d(-5px, 5px, 0px);
    transform: rotate(-6deg) translate3d(-5px, 5px, 0px);
