超酷！纯CSS3烧烤动画实现教程

今天在老外的网站上看到一款很有创意的纯CSS3动画，是模拟烧烤活动的。款动画模拟了一个烧烤架，烧烤架上的食物也都是用纯CSS3绘制而成，没有用一张图片，效果相当逼真。另外一个有意思的是，这个CSS3烧烤架还会冒烟，模拟了烧烤时的情景。

接下来简单分析一下实现的代码，代码主要由HTML和CSS组成。

HTML代码：

<div class="BBQ">
  <div class="meat"></div>
  <div class="sausage"></div>
  <div class="corn"></div>
  <div class="waterbamboo"></div>
  <div class="shrimp"></div>
  <div class="clams"></div>
  <div class="greenpepper"></div>
  <div class="smoke"></div>
</div>

HTML代码很简单，几个div就将整个烧烤架布局完了，当然重点还是CSS代码。

CSS代码：

这里先贴一下烧烤架的CSS代码，主要是实现一张网：

.BBQ {
  border-radius: 50%/20% 70%;
  box-shadow: 40px 48px 0 #333, -32px -49.6px 0 #333, -40px 25.6px 0 #333, 28.8px -36.8px 0 #333, 8px 80px #333, -64px 72px #333, 88px 19.2px #333, -104px 25.6px #333, -88px -25.6px #333, -96px 104px #333, -40px 128px #333, 24px 128px #333, 80px 96px #333, -16px 40px 0 120px #C33, -16px 40px 0 140px #333;
  position: relative;
  width: 40px;
  height: 40px;
  margin: 220px auto;
  background: #333;
}
.BBQ:before, .BBQ:after {
  box-shadow: 18.4px 0 0 #999, 36.8px 0 0 #999, 55.2px 0 0 #999, 73.6px 0 0 #999, 92px 0 0 #999, 110.4px 0 0 #999, 128.8px 0 0 #999, 147.2px 0 0 #999, 165.6px 0 0 #999, 184px 0 0 #999, 202.4px 0 0 #999, 220.8px 0 0 #999, 239.2px 0 0 #999, 257.6px 0 0 #999;
  display: block;
  position: absolute;
  top: -90px;
  left: -130px;
  width: 5px;
  height: 300px;
  background: #999;
}
.BBQ:after {
  -ms-transform: rotate(90deg);
  -webkit-transform: rotate(90deg);
  transform: rotate(90deg);
  top: -220px;
  left: 0;
}

然后我们对其中一种食物进行绘制，比如说绘制一个玉米：

.BBQ .corn {
  border-radius: 9px;
  box-shadow: 4px -2px 4px rgba(99, 33, 99, 0.3) inset, -10px -2px 10px rgba(99, 33, 99, 0.5) inset, 0 0 5px rgba(33, 33, 33, 0.3);
  position: absolute;
  top: 60px;
  left: -12px;
  width: 35px;
  height: 100px;
  background: #F2D204;
  z-index: 1;
}
.BBQ .corn:before {
  box-shadow: -1px 2px 2px 0 rgba(33, 33, 33, 0.5) inset;
  position: relative;
  top: 100%;
  display: block;
  margin: 0 auto;
  width: 5px;
  height: 30px;
  background: #F2E6CA;
}
.BBQ .corn:after {
  border-radius: 2px;
  filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=20);
  opacity: 0.2;
  box-shadow: 1px 1px 0 rgba(33, 33, 33, 0.3), 8px 0 0 #F2D204, 9px 1px 0 rgba(33, 33, 33, 0.5), 16px 0 0 #F2D204, 17px 1px 0 rgba(33, 33, 33, 0.5), 24px 0 0 #F2D204, 25px 1px 0 rgba(33, 33, 33, 0.2), 0 8px 0 #F2D204, 1px 9px 0 rgba(33, 33, 33, 0.3), 8px 8px 0 #F2D204, 9px 9px 0 rgba(33, 33, 33, 0.5), 16px 8px 0 #F2D204, 17px 9px 0 rgba(33, 33, 33, 0.5), 24px 8px 0 #F2D204, 25px 9px 0 rgba(33, 33, 33, 0.2), 0 16px 0 #F2D204, 1px 17px 0 rgba(33, 33, 33, 0.3), 8px 16px 0 #F2D204, 9px 17px 0 rgba(33, 33, 33, 0.5), 16px 16px 0 #F2D204, 17px 17px 0 rgba(33, 33, 33, 0.5), 24px 16px 0 #F2D204, 25px 17px 0 rgba(33, 33, 33, 0.2), 0 24px 0 #F2D204, 1px 25px 0 rgba(33, 33, 33, 0.3), 8px 24px 0 #F2D204, 9px 25px 0 rgba(33, 33, 33, 0.5), 16px 24px 0 #F2D204, 17px 25px 0 rgba(33, 33, 33, 0.5), 24px 24px 0 #F2D204, 25px 25px 0 rgba(33, 33, 33, 0.2), 0 32px 0 #F2D204, 1px 33px 0 rgba(33, 33, 33, 0.3), 8px 32px 0 #F2D204, 9px 33px 0 rgba(33, 33, 33, 0.5), 16px 32px 0 #F2D204, 17px 33px 0 rgba(33, 33, 33, 0.5), 24px 32px 0 #F2D204, 25px 33px 0 rgba(33, 33, 33, 0.2), 0 40px 0 #F2D204, 1px 41px 0 rgba(33, 33, 33, 0.3), 8px 40px 0 #F2D204, 9px 41px 0 rgba(33, 33, 33, 0.5), 16px 40px 0 #F2D204, 17px 41px 0 rgba(33, 33, 33, 0.5), 24px 40px 0 #F2D204, 25px 41px 0 rgba(33, 33, 33, 0.2), 0 48px 0 #F2D204, 1px 49px 0 rgba(33, 33, 33, 0.3), 8px 48px 0 #F2D204, 9px 49px 0 rgba(33, 33, 33, 0.5), 16px 48px 0 #F2D204, 17px 49px 0 rgba(33, 33, 33, 0.5), 24px 48px 0 #F2D204, 25px 49px 0 rgba(33, 33, 33, 0.2), 0 56px 0 #F2D204, 1px 57px 0 rgba(33, 33, 33, 0.3), 8px 56px 0 #F2D204, 9px 57px 0 rgba(33, 33, 33, 0.5), 16px 56px 0 #F2D204, 17px 57px 0 rgba(33, 33, 33, 0.5), 24px 56px 0 #F2D204, 25px 57px 0 rgba(33, 33, 33, 0.2), 0 64px 0 #F2D204, 1px 65px 0 rgba(33, 33, 33, 0.3), 8px 64px 0 #F2D204, 9px 65px 0 rgba(33, 33, 33, 0.5), 16px 64px 0 #F2D204, 17px 65px 0 rgba(33, 33, 33, 0.5), 24px 64px 0 #F2D204, 25px 65px 0 rgba(33, 33, 33, 0.2), 0 72px 0 #F2D204, 1px 73px 0 rgba(33, 33, 33, 0.3), 8px 72px 0 #F2D204, 9px 73px 0 rgba(33, 33, 33, 0.5), 16px 72px 0 #F2D204, 17px 73px 0 rgba(33, 33, 33, 0.5), 24px 72px 0 #F2D204, 25px 73px 0 rgba(33, 33, 33, 0.2), 0 80px 0 #F2D204, 1px 81px 0 rgba(33, 33, 33, 0.3), 8px 80px 0 #F2D204, 9px 81px 0 rgba(33, 33, 33, 0.5), 16px 80px 0 #F2D204, 17px 81px 0 rgba(33, 33, 33, 0.5), 24px 80px 0 #F2D204, 25px 81px 0 rgba(33, 33, 33, 0.2), 0 88px 0 #F2D204, 1px 89px 0 rgba(33, 33, 33, 0.3), 8px 88px 0 #F2D204, 9px 89px 0 rgba(33, 33, 33, 0.5), 16px 88px 0 #F2D204, 17px 89px 0 rgba(33, 33, 33, 0.5), 24px 88px 0 #F2D204, 25px 89px 0 rgba(33, 33, 33, 0.2);
  position: absolute;
  top: 2px;
  left: 0;
  display: block;
  width: 22%;
  height: 6%;
}

再比如绘制一个虾：

.BBQ .shrimp {
  border-radius: 60%/30% 40% 10% 70%;
  background-image: -webkit-radial-gradient(circle at center right, rgba(0, 0, 0, 0) 67%, #cc4a04 68%, #ef6921 74%, #ef6921 85%, rgba(33, 33, 33, 0.2) 86%, rgba(0, 0, 0, 0) 90%);
  background-image: radial-gradient(circle at center right, rgba(0, 0, 0, 0) 67%, #cc4a04 68%, #ef6921 74%, #ef6921 85%, rgba(33, 33, 33, 0.2) 86%, rgba(0, 0, 0, 0) 90%);
  position: absolute;
  top: -35px;
  left: -10px;
  display: block;
  width: 86px;
  height: 70px;
  z-index: 1;
}
.BBQ .shrimp:before {
  -ms-transform: rotate(24deg);
  -webkit-transform: rotate(24deg);
  transform: rotate(24deg);
  border-radius: 85% 85% 50% 50%/120% 120% 50% 50%;
  box-shadow: 1px -35px 0 -7px #EF6921, 0 -36px 1px -7px rgba(33, 33, 33, 0.2), 5px -23px 0 -8px #EF6921, 5px -23px 1px -7px rgba(33, 33, 33, 0.2), 0 -2px 0 0 rgba(222, 222, 222, 0.3) inset, -2px 1px 2px rgba(33, 33, 33, 0.2);
  position: absolute;
  top: -24px;
  left: 15px;
  display: block;
  width: 18px;
  height: 45px;
  background: #EF6921;
}
.BBQ .shrimp:after {
  border-radius: 50%;
  background-image: -webkit-radial-gradient(circle at top center, #ef6921 35%, rgba(0, 0, 0, 0) 36%), -webkit-radial-gradient(circle at center left, #ef6921 27%, #cc4a04 37%, rgba(0, 0, 0, 0) 38%);
  background-image: -webkit-radial-gradient(top center, circle, #ef6921 35%, rgba(0, 0, 0, 0) 36%), -webkit-radial-gradient(circle at center left, #ef6921 27%, #cc4a04 37%, rgba(0, 0, 0, 0) 38%);
  background-image: radial-gradient(circle at top center, #ef6921 35%, rgba(0, 0, 0, 0) 36%), radial-gradient(circle at center left, #ef6921 27%, #cc4a04 37%, rgba(0, 0, 0, 0) 38%);
  box-shadow: -13px -86px 0 -9px rgba(222, 222, 222, 0.5), -14px -85px 0 -7px #212121;
  position: absolute;
  top: 60px;
  left: 25px;
  display: block;
  width: 22px;
  height: 22px;
}

其他食物的CSS代码大家可以下载源码研究，也可以查看演示效果。
