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.

const styleElement = document.querySelector('style:not(.fcc-hide-header)');
assert.match(
  __helpers.removeWhiteSpace(styleElement.textContent),
  /\.item5{.*grid-column:.*}/g
);

item5 class should have a grid-column property which results in it consuming the last two columns of the grid.

const itemFive = document.querySelector('.item5');
const colStart = getComputedStyle(itemFive).gridColumnStart;
const colEnd = getComputedStyle(itemFive).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.include(correctResults, result);
