CSS flex-flow用法及代码示例


flex-flow属性是柔性盒布局模块的sub-property，也是flex-wrap和flex-direction的简写属性。

flex-flow:flex-direction flex-wrap;

属性值：

  • 行nowrap：它将行排列为与文本方向相同，并且wrap-flex的默认值为nowrap。用于指定该项目没有包装。它使项目用单行换行。

            border:2px solid black; 
            display:flex; 
            flex-flow:row nowrap;
