方法一:利用裁剪(该方法IE下不支持)
利用裁剪 clip-path: polygon(),直接画出一个三角 唯一一点需要算出大致百分比就可以画出来
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <style> .nav-box { display: flex; list-style: none; font-size: 14px; } .nav-box li { white-space: nowrap; color: #019fe9; background: #edf9ff; counter-increment: listCounter; clip-path: polygon(87% 0, 100% 50%, 87% 100%, 0 100%, 13% 50%, 0 0); line-height: 40px; padding: 0 25px; margin-right: -10px; } .nav-box li::before { content: counter(listCounter) "-"; } .nav-box .active { color: #fcfefe; background: #009fe9; } .nav-box .active ~ li { color: #8e8e8e; background: #ebedf0; } </style> </head> <body> <!-- 容器 --> <ol class="nav-box"> <li><a href="">规则说明</a></li> <li><a href="">参与活动</a></li> <li class="active" aria-current="true"><a href="">参与抽奖</a></li> <li><a href="">奖品发放</a></li> <li><a href="">查看结果</a></li> </ol> </body> </html>

方法二:利用错位
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <style scoped> .nav-box { display: flex; list-style: none; font-size: 14px; } .nav-box li { white-space: nowrap; color: #019fe9; padding: 0 15px 0 25px; line-height: 40px; margin-left: 3px; position: relative; z-index: 99; } .nav-box li:first-child{ background: #edf9ff; margin-right: 7px; } .nav-box .active:first-child{ background: #019fe9; } .nav-box li:first-child::before, .nav-box li:first-child::after{ left: 7px; } .nav-box li::before, .nav-box li::after { content: ""; position: absolute; left: 0; height: 50%; width: 100%; background: #edf9ff; z-index: -1; } .nav-box li::before { top: 0; transform: skew(30deg); } .nav-box li::after { bottom: 0; transform: skew(-30deg); } .nav-box .active { color: #d7effb; } .nav-box .active::before, .nav-box .active::after { background: #009fe9; } .active ~ li { color: #909091; } .active ~ li::before, .active ~ li::after { background: #ebedf0; } </style> </head> <body> <!-- 容器 --> <ol class="nav-box"> <li class="active">1-规则说明</li> <li>2-参与活动</li> <li>3-参与抽奖</li> <li>4-奖品发放</li> <li>5-参与结果</li> </ol> </body> </html>
方法三:border造三角
利用 border 生成前后三角
缺点是索引需要自己定义,不加标签情况下无法使用css计数器
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <style> .nav-box{ height:40px; line-height:40px; list-style: none; padding:0; display:flex; font-size:14px; overflow: hidden; } .nav-box li{ padding:0 10px 0 10px; margin-right: 18px; white-space: nowrap; position:relative; color:#019fe9; background:#edf9ff ; } /* 三角 */ .nav-box li:before,.nav-box li:after{ content:''; position:absolute; width: 0; height: 0; } .nav-box li:before{ right: -16px; border: solid transparent; border-width: 20px 0 20px 16px; border-left-color:#edf9ff; z-index:2; } /* 白线 */ .nav-box li:after{ top: -3px; left: -18px; border: solid #edf9ff; border-width: 23px 0 23px 18px; border-left-color: transparent; z-index: 1; } .nav-box .active{ color: #fff; background:#009fe9; } .nav-box .active ~ li{ color:#8e8e8e; background:#ebedf0; } .nav-box .active:before{ border-left-color:#009fe9; } .nav-box .active:after{ border-color: #009fe9; border-left-color: transparent; } .nav-box .active ~ li:before{ border-left-color:#ebedf0; } .nav-box .active ~ li:after{ border-color: #ebedf0; border-left-color: transparent; } </style> </head> <body> <ol class="nav-box"> <li>1-规则说明</li> <li>2-参与活动</li> <li class="active">3-参与抽奖</li> <li>4-奖品发放</li> <li>5-参与结果</li> </ol> </body> </html>
