纯CSS带阴影贴纸标签按钮效果：
<!doctype html> <html> <head> <meta charset="utf-8"> <title>CSS3带阴影贴纸标签按钮样式</title> <style> html { box-sizing: border-box; font: 18px PT Mono; background: antiquewhite; } *, *::before, *::after { box-sizing: inherit; } body { display: flex; align-items: center; justify-content: center; flex-direction: column; height: 100vh; } .box { width: 15%; min-width: 150px; display: block; height: 50px; position: relative; border-radius: 5px; background: linear-gradient(to right, #abbd73 35%, #d6e2ad 100%); margin-bottom: 40px; padding: 15px 25px 0 40px; color: darkslategray; box-shadow: 1px 2px 1px -1px #777; transition: background 200ms ease-in-out; text-align:right; } .box a{color:#fff;text-decoration:none;} .shadow { position: relative; } .shadow:before { z-index: -1; position: absolute; content: ""; bottom: 13px; right: 7px; width: 75%; top: 0; box-shadow: 0 15px 10px #777; -webkit-transform: rotate(4deg); transform: rotate(4deg); transition: all 150ms ease-in-out; } .box:hover { background: linear-gradient(to right, #abbd73 0%, #abbd73 100%); } .shadow:hover::before { -webkit-transform: rotate(0deg); transform: rotate(0deg); bottom: 20px; z-index: -10; } .circle { position: absolute; top: 14px; left: 15px; border-radius: 50%; box-shadow: inset 1px 1px 1px 0px rgba(0, 0, 0, 0.5), inset 0 0 0 25px antiquewhite; width: 20px; height: 20px; display: inline-block; text-align:right; padding:0 20px 0 0; } </style> </head> <body> <div class="box shadow"> <a href="#">Gary</a> <div class="circle"></div> </div> <div class="box shadow"> <a href="#">jQuery</a> <div class="circle"></div> </div> <div class="box shadow"> <a href="#">贴纸标签</a> <div class="circle"></div> </div> </div> </body> </html>
实现过程：
一、设置CSS样式
justify-content 用于设置或检索弹性盒子元素在主轴（横轴）方向上的对齐方式。
flex-start 默认值。项目位于容器的开头
flex-end 项目位于容器的结尾
center 项目位于容器的中心
space-between 项目位于各行之间留有空白的容器内
space-around 项目位于各行之前、之间、之后都留有空白的容器内
1、绘制标签盒子
.box {
width: 15%;
min-width: 150px;
display: block;
height: 50px;
position: relative;
border-radius: 5px;
background: linear-gradient(to right, #abbd73 35%, #d6e2ad 100%);
margin-bottom: 40px;
padding: 15px 25px 0 40px;
color: darkslategray;
box-shadow: 1px 2px 1px -1px #777;
transition: background 200ms ease-in-out;
text-align:right;
}
min-width ：设置元素的最小宽度。
border-radius：向 div 元素添加圆角边框
background: linear-gradient(direction, color-stop1, color-stop2, ...) 百度经验
linear-gradient(线性渐变)
radial-gradient(径向渐变)
direction：渐变方法
color-stop1, color-stop2：要呈现平稳过渡的颜色
margin-bottom ：设置元素的下外边距
color: darkslategray;深石板灰......（英语差）
transition:鼠标碰到时触发过度动画 传送门
2、绘制盒子阴影
.shadow:before {
z-index: -1;
position: absolute;
content: "";
bottom: 13px;
right: 7px;
width: 75%;
top: 0;
box-shadow: 0 15px 10px #777;
-webkit-transform: rotate(4deg);
transform: rotate(4deg);
transition: all 150ms ease-in-out;
}
z-index ：设置元素的堆叠顺序。拥有更高堆叠顺序的元素总是会处于堆叠顺序较低的元素的前面
使得阴影位于标签按钮下方
bottom ：规定盒子的底部边缘与阴影之间的偏移(调大了会有点丑∑(= = ！))
transform: rotate(4deg)定义 2D 旋转4度
3、绘制标签圆角
.circle {
position: absolute;
top: 14px;
left: 15px;
border-radius: 50%;
box-shadow: inset 1px 1px 1px 0px rgba(0, 0, 0, 0.5), inset 0 0 0 25px antiquewhite;
width: 20px;
height: 20px;
display: inline-block;
text-align:right;
padding:0 20px 0 0;
}
border-radius：向标签添加圆角边框
antiquewhite颜色：古董白(石材百科说是中国产花岗岩！！！)上一张图
二、在Body中给“标签”添加CSS样式
<body> <div class="box shadow"> <a href="#">Gary</a> <div class="circle"></div> </div> <div class="box shadow"> <a href="#">jQuery</a> <div class="circle"></div> </div> <div class="box shadow"> <a href="#">贴纸标签</a> <div class="circle"></div> </div> </div> </body>
