CSS3超酷响应式垂直时间轴特效

简介

在页面中引入bootstrap.min.css文件。

```html
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css" />
```
#####  HTML结构
该响应式垂直时间轴的基本HTML结构如下：

```html
<div class="container">
<div class="row">
    <div class="col-md-12">
        <div class="main-timeline">
            <div class="timeline">
                <a href="#" class="timeline-content">
                    <span class="year">2018</span>
                    <h3 class="title">标题</h3>
                    <p class="description">
                        描述文本
                    </p>
                </a>
            </div>
            <div class="timeline">
                <a href="#" class="timeline-content">
                    <span class="year">2017</span>
                    <h3 class="title">标题</h3>
                    <p class="description">
                        描述文本
                    </p>
                </a>
            </div>
        </div>
    </div>
	</div>  
```               
#####  CSS样式
然后通过下面的CSS样式来实现该垂直时间轴效果。

```html

    padding-top: 50px;
    position: relative;
}
.main-timeline:after{
    content: "";
    display: block;
