时间轴（自定义）

先上效果图：

项目中要求做成上面的效果，在swiper官网找了一下找到类似的，但是起始位置在中间，没办法，只能自己动手借用swiper的css（刚开始用swiper写的，有些样式懒得改。。。）做出自己想要的效果（细节方面没做好不要介意，手动捂脸！）

html：

<div id="big">
        <div class="swiper-container">
            <div class="swiper-wrapper">
                </div>
              </div> 
    </div>
    <div id="left">
        <div class="leftTitle">
        </div>
    </div>

css：

<link rel="stylesheet" href="https://unpkg.com/swiper/css/swiper.css"> 

.swiper-container{
        position: relative;
	width: 90%;
	height: 36px;
	/* margin: 50px auto; */
	padding: 48px 0 6px 0;
        }
.swiper-wrapper{
       /* width: 100%; */
       left: 0;
       /* float: left; */
       /* white-space:nowrap; */
       padding-left: 36px;
       /* border:1px red solid; */
        }
.swiper-slide{
	width: 108px !important;
        height: 1px;
        background:#00a0e9;
        display:block;

        }.swiper-slide:last-child{

	position: absolute;
	left: -16px;
	top: -30px;
	/* z-index: 999; */
	/* border:1px red solid; */
        }
.swiper-slide i{
	position: absolute;
	left: -16px;
	font-style: normal;
        top: 14px;
        width: 42px;
        display: block;
        text-align: center
	}
.orange{
        color:orange
        }.orange span{
         background: orange;
        }
