总结

本次作业难点在于flex容器和项目的属性，之前flex布局基本没基础过，运用还不是很熟练。

flex容器属性总结

1、flex-direction （控制flex元素方向） ：row、row-reverse、column、column-reverse

2、flex-wrap（元素换行）：nowrap、wrap、wrap-reverse

3、flex-flow（flex-direction和flex-wrap的缩写）：默认为flex-flow：row nowrap

4、justify-content（横轴的对齐方式）：flex-start、flex-end、center、space-between、space-around

5、align-items（纵轴对齐方式）：flex-start、flex-end、center

6、align-content（多根轴线的对齐方式，如果只有一根轴线则该属性无效）：flex-start、flex-end、center、space-between、space-around、stretch

flex项目属性总结

1、order定义项目排列顺序,索引越小超靠前,默认为0

2、flex-grow定义项目的放大比例,默认为0表示不放大, 即就算存在剩余空间也不放大

3、flex-shrink定义了项目的缩小比例,默认为1,即如何空间不足,则自动缩小项目来填充

4、flex-basis定义了项目占据的主轴空间,默认值为auto, 即项目原始大小

5、flex是flex-grow,flex-shrink,flex-basis简写,默认值: 0 1 auto, 后二个属性可选6align-self个性化定定制某单个项目的对齐方式,可覆盖容器`align-items`属性,默认auto
