## Description
|
|
<section id='description'>
|
|
Up to this point, all the properties that have been discussed are for grid containers. The <code>grid-column</code> property is the first one for use on the grid items themselves.
|
|
The hypothetical horizontal and vertical lines that create the grid are referred to as <dfn>lines</dfn>. These lines are numbered starting with 1 at the top left corner of the grid and move right for columns and down for rows, counting upward.
|
|
This is what the lines look like for a 3x3 grid:
|
|
<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;">column lines</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;">row lines</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>

To control the amount of columns an item will consume, you can use the <code>grid-column</code> property in conjunction with the line numbers you want the item to start and stop at.
|
|
Here's an example:
|
|
<blockquote>grid-column: 1 / 3;</blockquote>
|
|
This will make the item start at the first vertical line of the grid on the left and span to the 3rd line of the grid, consuming two columns.

|
|
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>.');
