20171026,今天需求要写一个带指向性箭头的步骤条,网上查找了一些示例,觉得用伪类这种方式还是挺好的,
优点显而易见,不需引用控件,不需复杂的代码,不需设计特定的背景图片,步骤条颜色可以在自己的样式代码里面自由控制,个人觉得还是很优秀的。
附一个样例代码:
<!DOCTYPE html>
<html><head>
<meta charset="UTF-8">
<title></title>
<style>
.cssNav li{
padding: 0px 20px 0 40px;
line-height: 40px;
background: #50abe4;
display: inline-block;
color: #fff;
position: relative;
}
.cssNav li:after{
content: '';
display: block;
border-top: 20px solid transparent;
border-bottom: 20px solid transparent;
border-left: 20px solid #50abe4;
position: absolute;
right: -20px;
top: 0;
z-index: 10;
}
.cssNav li:before{
content: '';
display: block;
border-top: 20px solid transparent;
border-bottom: 20px solid transparent;
border-left: 20px solid #fff;
position: absolute;
left: 0px;
top: 0;
}
.cssNav li:first-child{
border-radius: 4px 0 0 4px;
padding-left: 25px;
}
.cssNav li:last-child,.cssNavEnd{
border-radius: 0px 4px 4px 0px;
padding-right: 25px;
}
.cssNav li:first-child:before{
display: none;
}
.cssNav li:last-child:after,.cssNavEnd:after{
display: none;
}
.cssNav li.gone {
background-color: #DDDDDD;
color:#000000;
}
.cssNav li.gone:after {
border-left-color: #DDDDDD;
}
.cssNav li.active {
background-color: #ef72b6;
}
.cssNav li.active:after {
border-left-color: #ef72b6;
}
</style>
</head>
<body>
<ul class="cssNav">
<li class="gone">首页</li>
<li class="active">第一页</li>
<li>第二页</li>
<li>第三页</li>
</ul>
