css3 奇思妙想
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：'卧槽，卧槽，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（逼）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，作者 github 主页请戳 这里~
装逼指南
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。
装逼技巧
本文所有图形都会有个容器 <div></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>
<div></div>
</div>
天气那一块有部分会多一个容器，其结构如下：
<div>
<div>
<div></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
- 爱心
利用 div 的正方形和伪类的圆型组合而成，具体代码如下：
/*heart*/
.heart{
position: absolute;
top:50%;
left: 50%;
transform:translate(-50%,-50%) rotate(45deg);
background: red;
width: 100px;
height: 100px;
}
.heart:before,
.heart:after
{
content: '';
position: absolute;
top: 0;
left: -50px;
width: 100px;
height: 100px;
border-radius: 50%;
background: red;
}
.heart:after{
top: -50px;
left: 0;
}
- 气泡悬浮框
利用 border 结合 transparent 特性实现，代码如下：
/*bubbly*/
.bubbly{
position: absolute;
top:50%;
left: 50%;
transform:translate(-50%,-50%);

border-radius: 8px;
width: 200px;
padding: 40px 10px;
text-align: center;
color: white;
font-size: 20px;
}
.bubbly:after {
content: '';
position: absolute;
bottom: 0;
left: 50%;
border: 34px solid transparent;

top left,
linear-gradient(-135deg, transparent 15px, deeppink 0)
top right,
linear-gradient(-45deg, transparent 15px, deeppink 0)

- firefox
利用多重阴影实现 , 代码如下：
/*firefox*/
.firefox{
position: absolute;
top: 50%;left: 50%;
width: 200px;height:200px;
transform: translate(-50%, -50%);
border:8px solid #eee;
border-radius:50%;
overflow:hidden;
background:#F48D00;
box-shadow:0 0 2px 0 #999;
}
.firefox::before{
content: "";
width: 46px;
height: 46px;
background: #A4DFEF;
border-radius: 100%;
position: absolute;
top: 90px;
left: 50px;
margin: auto;
border: 1px solid #A4DFEF;
box-shadow:
-10px 0 0 5px rgba(164, 223, 239, .2),
16px -60px 0 8px rgba(164, 223, 239, .2),
-30px -50px 0 8px #F48D00,
25px -38px 0 0px #A4DFEF,
-30px -30px 0 12px #F48D00,

}
.firefox::after{
content: "";
width: 0px;
height: 2px;
background: linear-gradient(90deg,#F48D00 75% ,#333 30% );
background-size: 35px 35px;
position: absolute;
top: 50px;
left: 73px;
margin: auto;
border: solid;
border-width: 12px 0 15px 30px;
border-color: #A4DFEF #fff #A4DFEF transparent;
box-shadow: inset 0px 0 0 50px #333;
}
- 搜狗
利用文字、阴影实现 , 具体代码如下：
/*sougou*/
.sogou{
position: absolute;
top: 50%;
left: 50%;
width: 200px;height:200px;
transform: translate(-50%, -50%);
border:8px solid #fff;
box-shadow: 2px 1px 2px 2px #ccc;
border-radius:50%;
overflow:hidden;
background:#4DA0ED;
}
.sogou::before{
content:"S";
position: absolute;
line-height: 185px;
top:0;
left:0;
right:0;
bottom:0;
color:#fff;
font-weight:600;
font-size:320px;
text-align:center;
text-shadow:
3px 0 0px #337FC4,
-5px 0px 0px #CDE4F0,
0px 8px 0px #387FBF;
transform:rotate(2deg);
z-index:-10;
overflow:hidden;
}
- 利用滤镜实现混合效果
利用 fliter:blur() 、filter:contrast() 实现 ， 代码如下：
/*filter-mix*/
.filter-mix{
position: absolute;
top: 50%;left: 50%;
transform: translate(-50%, -50%);
width: 300px;height: 200px;
-webkit-filter:contrast(20);
background:#fff;
}
.filter-mix::before{
content:"";
position: absolute;
width:120px;
height:120px;
border-radius: 50%;
background:#333;
top:40px;
left:0px;
z-index:2;
-webkit-filter:blur(6px);
box-sizing:border-box;
animation:filterBallMove 10s ease-out infinite;
-webkit-animation:filterBallMove 10s ease-out infinite;
}
.filter-mix::after{
content:"";
position: absolute;
width:80px;
height:80px;
border-radius: 50%;
background:#3F51B5;
top:60px;
right:0px;
z-index:2;
-webkit-filter:blur(6px);
animation:filterBallMove2 10s ease-out infinite;
-webkit-animation:filterBallMove2 10s ease-out infinite;
}
@keyframes filterBallMove{
50%{
left:200px;
}
}
@-webkit-keyframes filterBallMove{
50%{
left:200px;
}
}
@keyframes filterBallMove2{
50%{
right:200px;
}
}
@-webkit-keyframes filterBallMove2{
50%{
right:200px;
}
}
