开脑洞系列——CSS3版天气预报

前言
前几天看了一篇文章 ， 颠覆了我对 CSS 认识，心中无数次蹦出一个念头：'WC，还能特么这么用，这特么太叼了' ...
于是我迫不及待想跟你们一起分享分享，以后你也可以在别人面前炫（装）耀（B）了~
ps：本文原创不是我，我只是搬运工，看到好东西与大家分享而已
装B指南
本文中，所有的图形都是在单个标签内实现的，大量使用了 CSS3 中的 ::before 、 ::after 伪元素， transparent 、 border，多重线性与径向渐变，多重内外阴影，如果你的效果不尽人意，请尝试在 Chrome 浏览器下预览。
装B技巧
本文所有图形都会有个容器 <div class="css-cell"></div>包裹，其样式结构如下：
.css-cell{
position: relative;
width: 100%;
height: 300px;
}
所有图形都是在容器内实现的，其结构如下：
<!--heart-->
<div class="css-cell">
<div class="heart"></div>
</div>
天气那一块有部分会多一个容器，其结构如下：
<div class="css-cell ">
<div class="breeze-container">
<div class="breeze"></div>
</div>
</div>
为了方便起见，下面图形的具体实现，我只会贴出对应的类相应的样式代码~
装逼实战

border-radius:5px;
}
.sun:before{
content:"";

height: 80px;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
border-radius:50%;
background:rgba(255, 238, 68, 1);
box-shadow: 0 0 0 15px rgba(255,255,0,0.2),0 0 15px #fff;

微风
利用border、transparent、实现，这个会多一层 div.breeze-container 包裹，样式代码如下：
/*breeze*/
.breeze-container{
position: absolute;
top: 50%;left: 50%;
width:200px;height:260px;
transform: translate(-50%, -50%);
text-align:center;

}
.breeze-container:after{
content:"";
position:absolute;
top:58%;
left:50%;
transform: translate(-50%, -50%);
width:6px;
height:70px;
background:#fff;
}
.breeze{
position:absolute;
top: 30%;
left: 50%;
transform: translate(-50%, -50%) rotate(1deg);
border-bottom:60px solid #fff;
border-left:5px solid transparent;
border-right:5px solid transparent;
animation: windmill 12s infinite linear;
transform-origin:50.5% 62px;
}
.breeze:before{

top: 75px;left: -1px;
content:"";
border-left:60px solid #fff;
border-top:5px solid transparent;
border-bottom:5px solid transparent;
transform:rotate(30deg);
}
@keyframes windmill{

}
100%{
transform: translate(-50%, -50%) rotate(360deg);
}
}

}
100% {
transform: translate(-50%, -50%) scale(1);
background: rgba(0, 0, 0, .5);
}
}

怎么样，是不是颠覆了你对 CSS3 的认识？
实际上 CSS3 带给我们的远不止这些东西，没有做不到，只有想不到，只有你脑洞够大，各种黑科技、酷炫的 CSS 必然也是手到擒来~
