--description--

目前为止,挑战里提到的属性都是应用于 flex 容器flex 子元素的父元素的。除此之外flex 子元素也有很多实用属性。

首先介绍的是 flex-shrink 属性。使用之后,如果 flex 容器太小,则子元素会自动缩小。当容器的宽度小于里面所有子元素的宽度之和时,所有子元素都会自动压缩。

子元素的 flex-shrink 接受数值作为属性值。数值越大,则该元素与其他元素相比会被压缩得更厉害。比如,一个项目的 flex-shrink 属性值为 1,另一个项目的 flex-shrink 属性值为 3,那么后者相比前者会受到 3 倍压缩。

--instructions--

请为 #box-1#box-2 添加 CSS 属性 flex-shrink,将 #box-1flex-shrink 属性值设为 1,将 #box-2 的属性值设为 2

--hints--

#box-1 元素应具有 flex-shrink 属性,其属性值应为 1

assert($('#box-1').css('flex-shrink') == '1');

#box-2 元素应具有 flex-shrink 属性,其属性值应为 2

assert($('#box-2').css('flex-shrink') == '2');
