| # --description--
 | |
| 
 | |
| Up to this point, all the properties that have been discussed are for grid containers. The `grid-column` 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 number of columns an item will consume, you can use the `grid-column` property in conjunction with the line numbers you want the item to start and stop at.
 | |
| 
 | |
| Here's an example:
 | |
| 
 | |
| ```css
 | |
| grid-column: 1 / 3;
 | |
| ```
 | |
| 
 | |
| 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.
 | |
| 
 | |
| # --instructions--
 | |
| 
 | |
| Make the item with the class `item5` consume the last two columns of the grid.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| `item5` class should have a `grid-column` property.
 | |
| 
 | |
| ```js
 | |
| assert(
 | |
|   __helpers
 | |
|     .removeWhiteSpace($('style').text())
 | |
|     .match(/\.item5{.*grid-column:.*}/g)
 | |
| );
 | |
| ```
 | |
| 
 | |
| `item5` class should have a `grid-column` property which results in it consuming the last two columns of the grid.
 | |
| 
 | |
| ```js
 | |
| const colStart = getComputedStyle($('.item5')[0]).gridColumnStart;
 | |
| const colEnd = getComputedStyle($('.item5')[0]).gridColumnEnd;
 | |
| const result = colStart.toString() + colEnd.toString();
 | |
| const correctResults = [
 | |
|   '24',
 | |
|   '2-1',
 | |
|   '2span 2',
 | |
|   '2span2',
 | |
|   'span 2-1',
 | |
|   '-12',
 | |
|   'span 2span 2',
 | |
|   'span 2auto',
 | |
|   'autospan 2'
 | |
| ];
 | |
| assert(correctResults.includes(result));
 | |
| ```
