这是使用CSS3功能的整个方法的替代方法。使用此方法的一个优点(以及添加单独答案的主要原因之一)是箭头之间的空间可以是透明的。
基本上实现如下:
div
每个步骤/项目都有一个,它包含需要显示的文本。让我们说height
这div
是x
(在这个例子中50px)。两个伪元素(
:before
和:after
)与它们的创建width
相同的父div
和height
作为半(x/2
父)。该:before
元件不具有border-bottom
而:after
元件不具有border-top
以避免出现在形状(平行于x轴)的中间的线。然后,这两个伪元件
skew
在相反的方向上变换,并且以这样的方式定位,使得它们直接在彼此下方,从而最终形成所需的形状。伪元素被赋予负数
z-index
以将它们推到父元素后面div
(因此它的文本)。的
first-child
和last-child
元件被稍微修改(left
位置,border
伪元素,的background
和border
的母体div
)来实现直边。我们可以
active
为活动元素和hover
效果添加一个类,如下面的示例所示。
.steps { height: 50px; width: 150px; text-align: center; line-height: 50px; position: relative; margin: 10px 0px 10px 20px; display: inline-block;}.steps:before,.steps:after { content: ''; position: absolute; left: 0px; width: 150px; height: 25px; z-index: -1;}.steps:before { top: -2px; border-top: 2px solid blue; border-right: 2px solid blue; border-left: 2px solid blue; background: lightblue; -moz-transform: skew(30deg); -webkit-transform: skew(30deg); transform: skew(30deg);}.steps:after { bottom: -2px; border-left: 2px solid blue; border-right: 2px solid blue; border-bottom: 2px solid blue; background: lightblue; -moz-transform: skew(-30deg); -webkit-transform: skew(-30deg); transform: skew(-30deg);}.steps:last-child { background: lightblue; border-right: 2px solid blue; border-top: 2px solid blue; border-bottom: 2px solid blue; margin-left: 38px;}.steps:first-child { background: lightblue; border-left: 2px solid blue; border-top: 2px solid blue; border-bottom: 2px solid blue; margin-right: 18px;}.steps:first-child:before,.steps:first-child:after { left: 18px;}.steps:last-child:before,.steps:last-child:after { left: -18px;}/* Hover Styles */.steps:first-child:hover,.steps:last-child:hover,.steps:hover:before,.steps:hover:after { background: lightgreen;}.steps:first-child:hover { border-left: 2px solid green;}.steps:last-child:hover { border-right: 2px solid green;}.steps:hover:before { border-top: 2px solid green; border-right: 2px solid green; border-left: 2px solid green;}.steps:hover:after { border-left: 2px solid green; border-right: 2px solid green; border-bottom: 2px solid green;}.steps:first-child:hover,.steps:last-child:hover { border-top: 2px solid green; border-bottom: 2px solid green;}/* Active Styles */.active:first-child,.active:last-child,.active:before, .active:after{ background: bisque;}.active:first-child{ border-left: 2px solid red;}.active:last-child{ border-right: 2px solid red;}.active:before{ border-top: 2px solid red; border-right: 2px solid red; border-left: 2px solid red;}.active:after{ border-left: 2px solid red; border-right: 2px solid red; border-bottom: 2px solid red;}.active:first-child, .active:last-child{ border-top: 2px solid red; border-bottom: 2px solid red;}/* Just for creating a non solid color background */body{ height: 200px; background: -webkit-radial-gradient(center, ellipse, #400, #100); background: -moz-radial-gradient(center, ellipse, #400, #100); background: radial-gradient(center, ellipse, #400, #100);}
<div class='steps-container'> <div class='steps'>1. Step 1</div> <div class='steps active'>2. Step 2</div> <div class='steps'>3. Step 3</div></div>
注:在hover
第一个孩子的右尖或最后一个孩子,因为z-index的问题的左尖盘旋当在上面的代码中不起作用。如果您需要无缝hover
功能,那么在下面的代码片段中使用元素span
内部.steps
就可以解决它。(感谢The Pragmatick指出这一点)。
.steps { height: 50px; width: 150px; text-align: center; line-height: 50px; position: relative; margin: 10px 0px 10px 20px; display: inline-block;}.steps span { position: relative; z-index: 2;}.steps:before,.steps:after { content: ''; position: absolute; left: 0px; width: 150px; height: 25px;}.steps:before { top: -2px; border-top: 2px solid blue; border-right: 2px solid blue; border-left: 2px solid blue; background: lightblue; -moz-transform: skew(30deg); -webkit-transform: skew(30deg); transform: skew(30deg);}.steps:after { bottom: -2px; border-left: 2px solid blue; border-right: 2px solid blue; border-bottom: 2px solid blue; background: lightblue; -moz-transform: skew(-30deg); -webkit-transform: skew(-30deg); transform: skew(-30deg);}.steps:first-child:before,.steps:first-child:after { border-left: none;}.steps:last-child:before,.steps:last-child:after { border-right: none;}.steps:last-child { background: lightblue; border-right: 2px solid blue; border-top: 2px solid blue; border-bottom: 2px solid blue; margin-left: 38px;}.steps:first-child { background: lightblue; border-left: 2px solid blue; border-top: 2px solid blue; border-bottom: 2px solid blue; margin-right: 18px;}.steps:first-child:before,.steps:first-child:after { left: 18px;}.steps:last-child:before,.steps:last-child:after { left: -18px;}/* Hover Styles */.steps:first-child:hover,.steps:last-child:hover,.steps:hover:before,.steps:hover:after { background: lightgreen;}.steps:first-child:hover { border-left: 2px solid green;}.steps:last-child:hover { border-right: 2px solid green;}.steps:hover:before { border-top: 2px solid green; border-right: 2px solid green; border-left: 2px solid green;}.steps:hover:after { border-left: 2px solid green; border-right: 2px solid green; border-bottom: 2px solid green;}.steps:first-child:hover,.steps:last-child:hover { border-top: 2px solid green; border-bottom: 2px solid green;}.steps:first-child:hover:before,.steps:first-child:hover:after { border-left: none;}.steps:last-child:hover:before,.steps:last-child:hover:after { border-right: none;}/* Active Styles */.active:first-child,.active:last-child,.active:before,.active:after { background: bisque;}.active:first-child { border-left: 2px solid red;}.active:last-child { border-right: 2px solid red;}.active:before { border-top: 2px solid red; border-right: 2px solid red; border-left: 2px solid red;}.active:after { border-left: 2px solid red; border-right: 2px solid red; border-bottom: 2px solid red;}.active:first-child,.active:last-child { border-top: 2px solid red; border-bottom: 2px solid red;}/* Just for creating a non solid color background */body { height: 200px; background: -webkit-radial-gradient(center, ellipse, #400, #100); background: -moz-radial-gradient(center, ellipse, #400, #100); background: radial-gradient(center, ellipse, #400, #100);}

具有透明背景的响应式实施:
对于具有半透明框的进度跟踪栏的响应版本,请访问此笔。每个步骤/项目的宽度以这样的方式分配,即它们的总和始终是可用宽度的100%,并且每个项目总是与其他项目的大小相同。
JavaScript用于以下功能:(所有这些功能都是增值功能,可以根据需要删除。请注意,删除JS后,应将相应的CSS属性放入CSS文件中。)
根据编号自动调整每个项目的宽度。栏中存在的项目
调整窗口大小时自动调整每个项目的宽度
使用滑块增加或减少条的高度时,自动调整项目的外观。

注意
