Description

有一个快捷方式可以同时设置多个flex属性。通过使用flex属性，可以将flex-grow ， flex-shrink和flex-basis属性设置在一起。例如， flex: 1 0 10px;将项目设置为flex-grow: 1; ， flex-shrink: 0; ，和flex-basis: 10px; 。默认属性设置为flex: 0 1 auto; 。

Instructions

将CSS属性flex添加到#box-1和#box-2 。给#box-1赋值，使flex-grow为2， flex-shrink为2， flex-basis为150px。给#box-2赋值，使flex-grow为1， flex-shrink为1，其flex-basis为150px。这些值将导致#box-1增长以在容器大于300px时以#box-2两倍速率填充额外空间，并在容器小于300px时以#box-2的速率缩小两倍。 300px是两个框的flex-basis值的组合大小。

Tests

tests:
  - text: '<code>#box-1</code>元素的<code>flex</code>属性应设置为2 2 150px。'
    testString: 'assert($("#box-1").css("flex-grow") == "2" && $("#box-1").css("flex-shrink") == "2" && $("#box-1").css("flex-basis") == "150px", "The <code>#box-1</code> element should have the <code>flex</code> property set to a value of 2 2 150px.");'
  - text: '<code>#box-2</code>元素的<code>flex</code>属性应设置为1 1 150px。'
    testString: 'assert($("#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>.");'
