原理
使用的border边框属性 结合svg 转换
详见代码
<!DOCTYPE html>
< html lang = " en" >
< head> < meta charset = " UTF-8" > < title> css实现div边框斜角</ title> < style type = " text/css" >
.labels { display : inline-block; display : inline-flex; color : #fff; line-height : 22px;
} .label { display : inline-block; text-align : center;
} .label.port { background-color : #636F80; width : 48px;
} .label.port::before { border-top : 11px solid transparent; border-right : 5px solid #636F80; border-bottom : 11px solid #636F80; border-left : 5px solid transparent;
} .label + .label { position : relative; z-index : 3;
} .label + .label .triangle { width : 22px; height : 22px; position : absolute; right : 100%; top : 0; margin-right : -8px;
} </ style>
</ head>
< body> < div class = " labels" > < span class = " label" style =" background-color : #2c968a; width : 102px; " > 127.0.0.1</ span> < span v-if = " row.url" class = " label port" > < svg class = " triangle" viewBox = " 0 0 1024 1024" xmlns: xlink= " http://www.w3.org/1999/xlink" > < path style =" fill : #636F80; " d = " M679.563636 2.771938h7.345635l-7.345635 1021.228062H336.443943z" /> </ svg> 8080</ span>
</ div>
</ body>
</ html>
效果如下:
