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); } }
