## Description
|
||
<section id="description">有一个快捷方式可以同时设置多个flex属性。通过使用<code>flex</code>属性，可以将<code>flex-grow</code> ， <code>flex-shrink</code>和<code>flex-basis</code>属性设置在一起。例如， <code>flex: 1 0 10px;</code>将项目设置为<code>flex-grow: 1;</code> ， <code>flex-shrink: 0;</code> ，和<code>flex-basis: 10px;</code> 。默认属性设置为<code>flex: 0 1 auto;</code> 。 </section>
|
||
|
||
## Instructions
|
||
<section id="instructions">将CSS属性<code>flex</code>添加到<code>#box-1</code>和<code>#box-2</code> 。给<code>#box-1</code>赋值，使<code>flex-grow</code>为2， <code>flex-shrink</code>为2， <code>flex-basis</code>为150px。给<code>#box-2</code>赋值，使<code>flex-grow</code>为1， <code>flex-shrink</code>为1，其<code>flex-basis</code>为150px。这些值将导致<code>#box-1</code>增长以在容器大于300px时以<code>#box-2</code>两倍速率填充额外空间，并在容器小于300px时以<code>#box-2</code>的速率缩小两倍。 300px是两个框的<code>flex-basis</code>值的组合大小。 </section>

||
- text: '<code>#box-2</code>元素的<code>flex</code>属性应设置为1 1 150px。'
|
||
testString: 'assert($("#box-2").css("flex-grow") == "1" && $("#box-2").css("flex-shrink") == "1" && $("#box-2").css("flex-basis") == "150px", "The <code>#box-2</code> element should have the <code>flex</code> property set to a value of 1 1 150px.");'
|
||
- text: '您的代码应该使用<code>#box-1</code>和<code>#box-2</code>的<code>flex</code>属性。'
|
||
testString: 'assert(code.match(/flex:\s*?\d\s+?\d\s+?150px;/g).length == 2, "Your code should use the <code>flex</code> property for <code>#box-1</code> and <code>#box-2</code>.");'
