今天分享给大家的是一个用纯CSS3实现的人物行走动画，在没有使用JavaScript的情况下，用CSS3技术将人物行走的姿态描绘得非常逼真。其实动画实现的原理也是比较简单的，将人物行走时的状态分割成多张图片，然后利用CSS3的动画属性将这些图片串联起来形成人物行走动画效果。
HTML代码
<div id="canvas"> <div class="sky"> <div class="cloud-1"></div> <div class="cloud-2"></div> <div class="cloud-3"></div> <div class="cloud-4"></div> <div class="cloud-5"></div> <div class="cloud-6"></div> <div class="cloud-7"></div> <div class="cloud-8"></div> </div> <div class="horizon"></div> <div class="ground"> <div class="sign-best"></div> <div class="sign-no-js"></div> <div class="sign-lots-of-divs"></div> <div class="sign-all-css"></div> </div> <!-- skeleton and shadow --> <div class="shadow"></div> <div class="me"> <div class="torso"> <div class="left leg"> <div class="left thigh"> <div class="left shin"> <div class="left foot"> <div class="left toes"></div> </div> </div> </div> </div> <!-- left leg --> <div class="right leg"> <div class="right thigh"> <div class="right shin"> <div class="right foot"> <div class="right toes"></div> </div> </div> </div> </div> <!-- right leg --> <div class="left arm"> <div class="left bicep"> <div class="left forearm"></div> </div> </div> <!-- left arm --> <div class="right arm"> <div class="right bicep"> <div class="right forearm"></div> </div> </div> <!-- right arm --> </div> <!-- torso --> </div> <!-- me --> <div class="overlay"></div> </div>
