CSS 形状和文本对齐问题

Question

我正在尝试创建一个非常简单的布局，其中 div 和 css 形状几乎相似。

My fiddle

所以我试图让看起来像箭头的 div 与两边的一些 div 对齐，其中包含文本。这相对简单，但我很难让它们对齐？

我现在有点卡住了，而且变得更糟了......

<div id="columnsservices" style="padding: 0px 0 60px 0;">


<div style="float: left; width: 900px;  padding: 0px 80px 0 32px; ">

DEMO 使用 CSS counters

<ol>
    <li><hr/><p>item 1</p></li>
    <li><hr/><p>item 2</p></li>
    <li><hr/><p>item 3</p></li>
</ol>

css：

*{
    margin:0;
    padding:0;
    box-sizing:border-box;
}
body{
    background:red;
}
ol {
    counter-reset:li; /*counter init*/   
}
 li {
    position:relative;
    list-style:none;
    width:100%;
    color:white;
    clear:both;
    display:block;
    margin-bottom:20px;
}
 li:before {
    content:"Step" counter(li);
    counter-increment:li;
    position:absolute;
    top:0;
    height:100%;
    width:145px;
    background:black;
    color:white;
}
li:nth-child(even):before{
    right:0;
}
li:nth-child(even){
    padding:0 120px 0 20px;
}
li:nth-child(even) p{
    width:40%; 
}
li:nth-child(odd):before{
    left:0;
}
li:nth-child(odd){
    padding:0 20px 0 220px;
}

li:nth-child(even):after,li:nth-child(odd):after{
    content:'';
    position:absolute;
    width:0;
    height:0;
    border-top:20px solid transparent;
    border-bottom:20px solid transparent;
    top:50%;
    margin-top:-16px;
}
li:nth-child(odd):after{
    border-left:20px solid black;
    left:142px;
}

li:nth-child(even):after{
    border-right:20px solid black;
    right:142px;
}
hr{
