HTML 部分非常简单，五种效果对应的class为：praticle、cells、jelly、blobbs、chase，代码如下：
<section> <div class="particle"></div> <div class="cells"></div> <div class="jelly"></div> <div class="blobbs"></div> <div class="chase"></div> </section>这些精美的效果用到了 CSS3 border-radius（圆角）、box-shadow（阴影）、transition（变形）、transform（转换）和 animation（动画）等特性，公共部分的完整代码如下：
section > div { display: inline-block; position: relative; width: 200px; height: 200px; margin: 0px auto; border-radius: 50%; border: 10px solid hsla(0,0%,0%,.7); box-shadow: inset 0 15px 15px -5px hsla(0,0%,100%,.7), inset 0 -5px 10px 3px hsla(0,0%,0%,.6), 0 8px 10px 2px hsla(0,0%,0%,.3); background-position: center; -webkit-transform: scale3d(.66,.66,1); -moz-transform: scale(.66); -ms-transform: scale(.66); -o-transform: scale(.66); transform: scale(.66); -webkit-transition: -webkit-transform .5s cubic-bezier(.32,0,.15,1); -moz-transition: -moz-transform .5s cubic-bezier(.32,0,.15,1); -ms-transition: -ms-transform .5s cubic-bezier(.32,0,.15,1); -o-transition: -o-transform .5s cubic-bezier(.32,0,.15,1); transition: transform .5s cubic-bezier(.32,0,.15,1); } section > div:hover { cursor: none; -webkit-transform: scale3d(1,1,1); -moz-transform: scale(1); -ms-transform: scale(1); -o-transform: scale(1); transform: scale(1); -webkit-transition: -webkit-transform .2s cubic-bezier(.32,0,.15,1); -moz-transition: -moz-transform .2s cubic-bezier(.32,0,.15,1); -ms-transition: -ms-transform .2s cubic-bezier(.32,0,.15,1); -o-transition: -o-transform .2s cubic-bezier(.32,0,.15,1); transition: transform .2s cubic-bezier(.32,0,.15,1); }这段代码看起来很长很复杂，其实大部分是兼容性代码，精简以后的代码如下：
section > div { display: inline-block; position: relative; width: 200px; height: 200px; margin: 0px auto; border-radius: 50%; border: 10px solid hsla(0,0%,0%,.7); box-shadow: inset 0 15px 15px -5px hsla(0,0%,100%,.7), inset 0 -5px 10px 3px hsla(0,0%,0%,.6), 0 8px 10px 2px hsla(0,0%,0%,.3); background-position: center; transform: scale(.66); transition: transform .5s cubic-bezier(.32,0,.15,1); } section > div:hover { cursor: none; transform: scale(1); transition: transform .2s cubic-bezier(.32,0,.15,1); }上面的代码中用到了贝塞尔曲线，在数学的数值分析领域中，贝塞尔曲线又称贝赛尔曲线（Bézier曲线）是电脑图形学中相当重要的参数曲线。更高维度的广泛化贝塞尔曲线就称作贝塞尔曲面，其中贝塞尔三角是一种特殊的实例。
贝塞尔曲线于1962年，由法国工程师皮埃尔·贝塞尔（Pierre Bézier）所广泛发表，他运用贝塞尔曲线来为汽车的主体进行设计。贝塞尔曲线最初由Paul de Casteljau于1959年运用de Casteljau算法开发，以稳定数值的方法求出贝塞尔曲线。
想更加深入的了解贝塞尔曲线可以到维基百科了解：贝塞尔曲线。下面是五种效果的完整代码：
效果一（Praticle）的完整代码：
.particle { background-size: 12px 12px; background-color: #000; box-shadow: inset 0 15px 15px -5px hsla(0,0%,100%,.25), inset 0 -5px 10px 3px hsla(0,0%,0%,.6), 0 8px 10px 2px hsla(0,0%,0%,.3); background-image: -webkit-radial-gradient( #555 0px, hsla(0,0%,0%,0) 2px, hsla(0,0%,0%,0) 24px), -webkit-repeating-radial-gradient( white 0px, black 2px, black 48px); background-image: -moz-radial-gradient( #555 0px, hsla(0,0%,0%,0) 2px, hsla(0,0%,0%,0) 24px), -moz-repeating-radial-gradient( white 0px, black 2px, black 48px); background-image: -ms-radial-gradient( #555 0px, hsla(0,0%,0%,0) 2px, hsla(0,0%,0%,0) 24px), -ms-repeating-radial-gradient( white 0px, black 2px, black 48px); background-image: -o-radial-gradient( #555 0px, hsla(0,0%,0%,0) 2px, hsla(0,0%,0%,0) 24px), -o-repeating-radial-gradient( white 0px, black 2px, black 48px); background-image: radial-gradient( #555 0px, hsla(0,0%,0%,0) 2px, hsla(0,0%,0%,0) 24px), repeating-radial-gradient( white 0px, black 2px, black 48px); } .particle:hover { -webkit-animation: particle-size .24s linear infinite, particle-positon .48s linear infinite alternate; -moz-animation: particle-size .24s linear infinite, particle-positon .48s linear infinite alternate; -ms-animation: particle-size .24s linear infinite, particle-positon .48s linear infinite alternate; -o-animation: particle-size .24s linear infinite, particle-positon .48s linear infinite alternate; animation: particle-size .24s linear infinite, particle-positon .48s linear infinite alternate; } @-webkit-keyframes particle-size { from { background-size: 6px 6px, 12px 12px; } to { background-size: 12px 12px, 24px 24px; } } @-moz-keyframes particle-size { from { background-size: 6px 6px, 12px 12px; } to { background-size: 12px 12px, 24px 24px; } } @-ms-keyframes particle-size { from { background-size: 6px 6px, 12px 12px; } to { background-size: 12px 12px, 24px 24px; } } @-o-keyframes particle-size { from { background-size: 6px 6px, 12px 12px; } to { background-size: 12px 12px, 24px 24px; } } @keyframes particle-size { from { background-size: 6px 6px, 12px 12px; } to { background-size: 12px 12px, 24px 24px; } } @-webkit-keyframes particle-positon { from { background-position: 60px, 60px; } to { background-position: 140px, 140px; } } @-moz-keyframes particle-positon { from { background-position: 60px, 60px; } to { background-position: 140px, 140px; } } @-ms-keyframes particle-positon { from { background-position: 60px, 60px; } to { background-position: 140px, 140px; } } @-o-keyframes particle-positon { from { background-position: 60px, 60px; } to { background-position: 140px, 140px; } } @keyframes particle-positon { from { background-position: 60px, 60px; } to { background-position: 140px, 140px; } }这个效果使用了 CSS3 radial-gradient（径向渐变或者放射性渐变，另外一种是线性渐变）、repeating-radial-gradient（重复渐变）以及 CSS3 Animation（动画），关于 CSS3 渐变的详细使用方法可以参考这篇文章：CSS3 Gradient，CSS3 动画可以参考这篇文章：CSS3 Animation。
为了便于阅读和学习，效果一的代码精简后如下：
.particle { background-size: 12px 12px; background-color: #000; box-shadow: inset 0 15px 15px -5px hsla(0,0%,100%,.25), inset 0 -5px 10px 3px hsla(0,0%,0%,.6), 0 8px 10px 2px hsla(0,0%,0%,.3); background-image: radial-gradient( #555 0px, hsla(0,0%,0%,0) 2px, hsla(0,0%,0%,0) 24px), repeating-radial-gradient( white 0px, black 2px, black 48px); } .particle:hover { animation: particle-size .24s linear infinite, particle-positon .48s linear infinite alternate; } @keyframes particle-size { from { background-size: 6px 6px, 12px 12px; } to { background-size: 12px 12px, 24px 24px; } } @keyframes particle-positon { from { background-position: 60px, 60px; } to { background-position: 140px, 140px; } }效果二（Cells）的完整代码：
.cells { background-size: 24px 24px; background-color: #fff; background-image: -webkit-repeating-radial-gradient( black 8px, white 12px); background-image: -moz-repeating-radial-gradient( black 8px, white 12px); background-image: -ms-repeating-radial-gradient( black 8px, white 12px); background-image: -o-repeating-radial-gradient( black 8px, white 12px); background-image: repeating-radial-gradient( black 8px, white 12px); } .cells:hover { -webkit-animation: cells 0.4s linear infinite; -moz-animation: cells 0.4s linear infinite; -ms-animation: cells 0.4s linear infinite; -o-animation: cells 0.4s linear infinite; animation: cells 0.4s linear infinite; } @-webkit-keyframes cells { from { background-size: 12px 12px; } to { background-size: 24px 24px; } } @-moz-keyframes cells { from { background-size: 12px 12px; } to { background-size: 24px 24px; } } @-ms-keyframes cells { from { background-size: 12px 12px; } to { background-size: 24px 24px; } } @-o-keyframes cells { from { background-size: 12px 12px; } to { background-size: 24px 24px; } } @keyframes cells { from { background-size: 12px 12px; } to { background-size: 24px 24px; } }效果二代码和效果一代码类似，差别是效果二的背景是只用了重复渐变（repeating-radial-gradient），动画效果只是背景尺寸（background-size）的变化，精简后的代码如下：
.cells { background-size: 24px 24px; background-color: #fff; background-image: repeating-radial-gradient( black 8px, white 12px); } .cells:hover { animation: cells 0.4s linear infinite; } @keyframes cells { from { background-size: 12px 12px; } to { background-size: 24px 24px; } }效果三（Jelly）的完整代码：
.jelly { background-size: 60px 60px; background-color: hsla(320,80%,60%,1); background-image: -webkit-repeating-radial-gradient( hsla(320,100%,60%,.6) 0px, hsla(220,100%,60%,0) 60%), -webkit-repeating-radial-gradient( hsla(330,100%,40%,1) 12%, hsla(320,80%,60%,1) 24px); background-image: -moz-repeating-radial-gradient( hsla(320,100%,60%,.6) 0px, hsla(220,100%,60%,0) 60%), -moz-repeating-radial-gradient( hsla(330,100%,40%,1) 12%, hsla(320,80%,60%,1) 24px); background-image: -ms-repeating-radial-gradient( hsla(320,100%,60%,.6) 0px, hsla(220,100%,60%,0) 60%), -ms-repeating-radial-gradient( hsla(330,100%,40%,1) 12%, hsla(320,80%,60%,1) 24px); background-image: -o-repeating-radial-gradient( hsla(320,100%,60%,.6) 0px, hsla(220,100%,60%,0) 60%), -o-repeating-radial-gradient( hsla(330,100%,40%,1) 12%, hsla(320,80%,60%,1) 24px); background-image: repeating-radial-gradient( hsla(320,100%,60%,.6) 0px, hsla(220,100%,60%,0) 60%), repeating-radial-gradient( hsla(330,100%,40%,1) 12%, hsla(320,80%,60%,1) 24px); } .jelly:hover { -webkit-animation: jelly 1.4s cubic-bezier(.1,.4,.9,.6) infinite; -moz-animation: jelly 1.4s cubic-bezier(.1,.4,.9,.6) infinite; -ms-animation: jelly 1.4s cubic-bezier(.1,.4,.9,.6) infinite; -o-animation: jelly 1.4s cubic-bezier(.1,.4,.9,.6) infinite; animation: jelly 1.4s cubic-bezier(.1,.4,.9,.6) infinite; } @-webkit-keyframes jelly { from { background-size: 60px 60px, 24px 24px; } 50% { background-size: 120px 120px, 100px 100px; } to { background-size: 24px 24px, 140px 140px; } } @-moz-keyframes jelly { from { background-size: 60px 60px, 24px 24px; } 50% { background-size: 120px 120px, 100px 100px; } to { background-size: 24px 24px, 140px 140px; } } @-ms-keyframes jelly { from { background-size: 60px 60px, 24px 24px; } 50% { background-size: 120px 120px, 100px 100px; } to { background-size: 24px 24px, 140px 140px; } } @-o-keyframes jelly { from { background-size: 60px 60px, 24px 24px; } 50% { background-size: 120px 120px, 100px 100px; } to { background-size: 24px 24px, 140px 140px; } } @keyframes jelly { from { background-size: 60px 60px, 24px 24px; } 50% { background-size: 120px 120px, 100px 100px; } to { background-size: 24px 24px, 140px 140px; } }效果三和效果一的代码类似，不同的地方是动画多了个 50% 关键帧，精简后的代码如下：
.jelly { background-size: 60px 60px; background-color: hsla(320,80%,60%,1); background-image: repeating-radial-gradient( hsla(320,100%,60%,.6) 0px, hsla(220,100%,60%,0) 60%), repeating-radial-gradient( hsla(330,100%,40%,1) 12%, hsla(320,80%,60%,1) 24px); } .jelly:hover { animation: jelly 1.4s cubic-bezier(.1,.4,.9,.6) infinite; } @keyframes jelly { from { background-size: 60px 60px, 24px 24px; } 50% { background-size: 120px 120px, 100px 100px; } to { background-size: 24px 24px, 140px 140px; } }效果四（Blobbs）的完整代码：
