## Description
<section id="description">将元素转换为网格只会影响其直接后代的行为。因此，通过将直接后代转换为网格，您在网格中有一个网格。例如，通过使用<code>item3</code>类设置元素的<code>display</code>和<code>grid-template-columns</code>属性，可以在网格中创建网格。 </section>

## Instructions
<section id="instructions">使用<code>item3</code>类将元素转换为网格，其中两列的宽度为<code>auto</code> ， <code>1fr</code>使用<code>display</code>和<code>grid-template-columns</code> 。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>item3</code>类应该有一个<code>grid-template-columns</code>属性，其中<code>auto</code>和<code>1fr</code>作为值。
    testString: 'assert(code.match(/.item3\s*?{[\s\S]*grid-template-columns\s*?:\s*?auto\s*?1fr\s*?;[\s\S]*}/gi), "<code>item3</code> class should have a <code>grid-template-columns</code> property with <code>auto</code> and <code>1fr</code> as values.");'
  - text: <code>item3</code>类应该具有<code>grid</code>值的<code>display</code>属性。
    testString: 'assert(code.match(/.item3\s*?{[\s\S]*display\s*?:\s*?grid\s*?;[\s\S]*}/gi), "<code>item3</code> class should have a <code>display</code> property with the value of <code>grid</code>.");'
