語(yǔ)法：

flex-wrap：nowrap | wrap | wrap-reverse

默認(rèn)值：nowrap

適用于：flex容器

繼承性：無(wú)

動(dòng)畫(huà)性：否

計(jì)算值：指定值

取值：

  • nowrap：flex容器為單行。該情況下flex子項(xiàng)可能會(huì)溢出容器

  • wrap：flex容器為多行。該情況下flex子項(xiàng)溢出的部分會(huì)被放置到新行，子項(xiàng)內(nèi)部會(huì)發(fā)生斷行

  • wrap-reverse：反轉(zhuǎn) wrap 排列。

說(shuō)明：

該屬性控制flex容器是單行或者多行，同時(shí)橫軸的方向決定了新行堆疊的方向。

  • 對(duì)應(yīng)的腳本特性為flexWrap。
