Description

当然，和设置一个网格项占用多列一样，你也可以设置它占用多行。你可以使用grid-row属性来定义一个网格项开始和结束的水平线。

Instructions

使类为item5的元素占用最后两行。

Tests

tests:
  - text: '<code>item5</code>类应该有<code>grid-row</code>属性且值为<code>2 / 4</code>。'
    testString: assert($('style').text().replace(/\s/g, '').match(/\.item5{.*grid-row:.*}/g));
  - text: '<code>item5</code> class 应该有 <code>grid-row</code> 属性使其占用网格最后两行。'
    testString: "
      const rowStart = getComputedStyle($('.item5')[0]).gridRowStart;
      const rowEnd = getComputedStyle($('.item5')[0]).gridRowEnd;
      const result = rowStart.toString() + rowEnd.toString();
      const correctResults = ['24', '2-1', '2span 2', '2span2', 'span 2-1', '-12', 'span 2span 2', 'span 2auto', 'autospan 2'];
      assert(correctResults.includes(result));
    "
