纯CSS3制作皮卡丘动画壁纸

前言
明天就放假了，趁着今晚的空挡时间来写这篇博客——这是我昨晚实现的一个简单的CSS3动画效果。话说还得缘起我逛了一下站酷网，然后不小心看到了一张皮卡丘的手机壁纸，觉得很可爱，然后觉得这种效果是可以用CSS3来实现的，于是带着好感就实现了它。至于原图吧，为了不影响大家对我实现的动画产生对比，我就有心地不放上来了，哈哈！那么到底是什么效果呢？接着往下看吧！

正文
OK，接下来就是晒效果图的时候了，看图后才有兴趣了解一下，不然很沉闷，没什么心思看了。



PS：由于我这个动画的尺寸做得比较大（720 x 1280），所以为了能录这个gif动画，我缩小了一倍。但是其实按原尺寸看效果会更好一些，这个的话，可以在文章结尾处我提供的地址下载。
言归正传，其实这个动画效果并不难，大家可以看到这个结构是非常简单清晰的。不过虽然简单，但是呈现出来的效果还是很不错的，这也是我为什么愿意做的原因。
好的，既然这么简单，就来看一下我实现它的html结构吧：

<div class="pikachu_container">
<div class="header">
<div class="header_main">
<span class="battery"></span>
<span class="clock" id="nowTime">09:00</span>
</div>
</div>
<div class="time">
<h1>09:00</h1>
<p id="date">2015年 9月3日</p>
<p>比卡丘可爱手机壁纸</p>
</div>
<div class="body">
<div class="eyes">
<div class="leftEye"></div>
<div class="rightEye"></div>
</div>
<div class="nose"></div>
<div class="cheek">
<div class="leftCheek"></div>
<div class="rightCheek"></div>
</div>
<div class="mouth">
<div class="mouth_main">
<div class="tongue"></div>
</div>
</div>
<div class="hands">
<div class="leftHand">
<div class="leftHand_main">
<span></span>
<span></span>
<span></span>
<span></span>
<div class="leftshadow"></div>
</div>
</div>
<div class="rightHand">
<div class="rightHand_main">
<span></span>
<span></span>
<span></span>
<span></span>
<div class="rightshadow"></div>
</div>
</div>
</div>
<div class="box">
<div class="box_main">
<div class="box_circle"></div>
</div>
</div>
</div>
<p class="author">@JR</p>
</div>

结构主线还是比较清晰的，整体上分为顶部电池和时间，中部的时间日期，还有皮卡丘的身体。而皮卡丘的身体又分为眼睛，鼻子，嘴巴，脸颊，双手和球。
把html结构搭建好了之后，就可以根据自己对该图测量出来的各部分的尺寸进行CSS样式的编写。
那么接下来我就把每一个部分的CSS实现代码分享给大家：

首先初始化一下

*{

皮卡丘的嘴巴还是值得琢磨的，最主要还是用了border-radius来完成这个效果。这个圆角特性还是蛮强大的，主要是看怎么去使用它。

PS：至于双手的手，由于事先的代码比较多，加上篇幅已经有点长，所以就不拿上来了。需要的话可以到我的github下载。
