## Description
<section id="description">到目前为止，所讨论的所有属性都是针对网格容器的。 <code>grid-column</code>属性是第一个用于网格项本身的属性。网格的水平线和垂直线被称为<dfn>line</dfn> 。这些线在网格的左上角从1号线开始，从左向右，从上向下移动。3x3的网格线条是这个样子： <div style="position:relative;margin:auto;background:Gainsboro;display:block;margin-top:100px;margin-bottom:50px;width:200px;height:200px;"><p style="left:25%;top:-30%;font-size:130%;position:absolute;color:RoyalBlue;">列线</p><p style="left:0%;top:-15%;font-size:130%;position:absolute;color:RoyalBlue;"> 1 </p><p style="left:30%;top:-15%;font-size:130%;position:absolute;color:RoyalBlue;"> 2 </p><p style="left:63%;top:-15%;font-size:130%;position:absolute;color:RoyalBlue;"> 3 </p><p style="left:95%;top:-15%;font-size:130%;position:absolute;color:RoyalBlue;"> 4 </p><p style="left:-40%;top:45%;font-size:130%;transform:rotateZ(-90deg);position:absolute;">横向线</p><p style="left:-10%;top:-10%;font-size:130%;position:absolute;"> 1 </p><p style="left:-10%;top:21%;font-size:130%;position:absolute;"> 2 </p><p style="left:-10%;top:53%;font-size:130%;position:absolute;"> 3 </p><p style="left:-10%;top:85%;font-size:130%;position:absolute;"> 4 </p><div style="left:0%;top:0%;width:5%;height:100%;background:RoyalBlue;position:absolute;"></div><div style="left:31%;top:0%;width:5%;height:100%;background:RoyalBlue;position:absolute;"></div><div style="left:63%;top:0%;width:5%;height:100%;background:RoyalBlue;position:absolute;"></div><div style="left:95%;top:0%;width:5%;height:100%;background:RoyalBlue;position:absolute;"></div><div style="left:0%;top:0%;width:100%;height:5%;background:black;position:absolute;"></div><div style="left:0%;top:31%;width:100%;height:5%;background:black;position:absolute;"></div><div style="left:0%;top:63%;width:100%;height:5%;background:black;position:absolute;"></div><div style="left:0%;top:95%;width:100%;height:5%;background:black;position:absolute;"></div></div>如果要控制项目是怎么占用的列数的话，您可以在<code>grid-column</code>属性后面加入您希望的项目开始和结束的网格线号。例如： <blockquote> grid-column：1/3; </blockquote>这将会让使项目从左侧第一条网格垂直线开始，一直延伸到网格的第3条线，占据两个网格列。 </section>

## Instructions
<section id="instructions">使用<code>item5</code>class使项目占据网络格的最后两列。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>item5</code>类应该有一个<code>grid-column</code>具有的值属性<code>2 / 4</code>
    testString: 'assert(code.match(/.item5\s*?{[\s\S]*grid-column\s*?:\s*?2\s*?\/\s*?4\s*?;[\s\S]*}/gi), "<code>item5</code> class should have a <code>grid-column</code> property that has the value of <code>2 / 4</code>.");'

```
