.test:after {display:inline-block content:"^" transform:rotate(180deg) scale(1.4,0.8)}
</style>
<span class="test">服务</span>
根据你的图片，达到这种效果有2种方法：
1.用图片png图片作为背景；
2.可以用纯css就可以达到，举个例子：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
body{
background-color: #444
}
.test{
width: 15px
height: 30px
box-sizing:border-box
border-top: 15px solid #f5f5f5
border-bottom: 15px solid #f5f5f5
/*border-left: 20px solid #0f0*/
border-right: 15px solid transparent
/* border-top-right-radius: 4px
border-radius: 12px*/
}
.csspic{
width: 200px
height: 400px
margin:50px auto
background: url(images/5.jpg) -15px top no-repeat
-webkit-background-size: cover
background-size: cover
border-radius: 10px
position: relative
border: 15px solid #f5f5f5
-moz-background-clip: border
-webkit-background-clip: border-box
-o-background-clip: border-box
background-clip: border-box
}
.img{
overflow: hidden
width: 260px
height: 400px
}
.sjx{
position: absolute
top:30px
left: -15px
background: url(images/5.jpg) left -30px no-repeat
-webkit-background-size: 500px
background-size: 500px
z-index: 9999
}
.csspic img{
height: 100%
}
</style>
</head>
<body>
<div class="csspic">
<div class="sjx">
<div class="test"></div>
</div>
<div class="img"><!-- <img src="images/5.jpg">--></div>
</div>
</body>
</html>
你好，我这里用CSS实现了三种带边框三角，效果分别如图：
实例代码如下，根据你个人的情况调整代码吧：
<!DOCTYPE html><html lang="en">
<head>
<meta charset="UTF-8">
<title>Arrow</title>
</head>
<body>
<style>
/* scale */
.arrow,
.arrow:after{
position: relative
display: inline-block
width: 0
height: 0
border-top: 0
border-left: 30px dotted transparent
border-right: 30px dotted transparent
border-bottom: 30px dashed #000
}
.arrow:after {
position: absolute
top: 0
content: ''
transform: translateX(-50%) scale(.8)
border-bottom: 30px dashed #fff
}
/* width & height */
.arrow1,
.arrow1:after {
position: relative
display: inline-block
width: 0
height: 0
border-top: 0
border-left: 30px dotted transparent
border-right: 30px dotted transparent
border-bottom: 30px dashed #000
}
.arrow1:after {
position: absolute
left: -26px
top: 2px
content: ''
width: 0
height: 0
border-top: 0
border-left: 26px dotted transparent
border-right: 26px dotted transparent
border-bottom: 26px dashed #fff
}
/* border & after */
.arrow2 {
position: relative
display: inline-block
width: 28px
height: 28px
border: 0
border-top: 2px solid #000
border-right: 2px solid #000
-webkit-transform: translate(7px, 14px) rotate(-45deg)
-ms-transform: translate(7px, 14px) rotate(-45deg)
-o-transform: translate(7px, 14px) rotate(-45deg)
transform: translate(7px, 14px) rotate(-45deg)
}
.arrow2:after {
position: absolute
left: 0
top: -2px
width: 42px
height: 2px
content: ''
border-radius: 2px
background-color: #000
-webkit-transform-origin: left top
-moz-transform-origin: left top
-ms-transform-origin: left top
-o-transform-origin: left top
transform-origin: left top
-webkit-transform: rotate(45deg)
-ms-transform: rotate(45deg)
-o-transform: rotate(45deg)
transform: rotate(45deg)
}
</style>
<span class="arrow"></span>
<span class="arrow1"></span>
<span class="arrow2"></span>
</body>
</html>
希望能帮到你，如有疑问请追问，望采纳~
