父:html
display:flex;web
父屬性設置瀏覽器
row | row-reverse | column | column-reverse;
flex-start | flex-end | center | space-between | space-around;
flex-start | flex-end | center | baseline | stretch;
flex-start | flex-end | center | space-between | space-around | stretch;
子屬性設置佈局
order:number 越小越前
flex-grow :0 無變化 剩餘長度按比例分配
flex-shrink:0 無變化 按比例縮小
flex-basis :auto /固定的值
flex:none
[ <'flex-grow'> <'flex-shrink'>? || <'flex-basis'> ]align-self:auto | flex-start | flex-end | center | baseline | stretch;
子元素上下的對其方式
css display:box 新屬性 post
https://www.cnblogs.com/whiteMu/p/5378747.htmlflex
1、display:box;ui
在元素上設置該屬性,可以使其子代排列在同一水平上,相似display:inline-block;。flexbox
2、可在其子代設置以下屬性spa
前提:使用以下屬性,必須在父代設置display:box;
1.box-flex:number;
1)佔父級元素寬度的number份
2)若子元素設置固定寬度,則該子元素應用固定寬度,其餘未設置固定寬度的字元素將餘下的父級寬度(父級-已設置固定寬度的子代元素的總寬度按 number佔份數
3)若子元素有margin值,則按餘下(父級寬度-子代固定總寬度-總margin值)寬度佔number份
2.box-orient:horizontal/vertical
在父級上設置該屬性,則子代按水平排列或豎直排列。
注:全部主流瀏覽器不支持該屬性,必須加上前綴。
1)horizontal 水平排列,子代總width=父級width。若父級固定寬度,則子代設置的width無效,子代會撐滿父級寬度。
2)vertical 垂直排列,子代總height=父級height。若父級固定高度,則子代設置的height無效,子代會撐滿父級高度。
3.box-direction:normal/reverse
在父級上設置該屬性,確認子代的排列順序。
1)normal 默認值,子代按html順序排列
2)reverse 反序
4.box-align:start/end/center/stretch
在父級設置,子代的垂直對齊方式。
1)start 垂直頂部對齊
2)end 垂直底部對齊
3)center 垂直居中對齊
4)stretch 拉伸子代的高度,與父級設置的高度一致。子代height無效。
5.box-pack:start/end/center
在父級設置,子代的水平對齊方式。
1)start 水平左對齊
2)end 水平右對齊
3)center 水平居中對齊

-ms-flex-direction: row|row-reverse|column|column-reverse
-ms-flex-align:start|end|center|stretch|baseline =flex的align-items
-ms-flex-pack:start|end|cener|justify =flex的justify-content
-ms-flex-wrap:nowrap|wrap|wrap-reverse
-ms-flex:<positive-flex> <negative-flex> <preferred-size> =flex的flex
-ms-flex-order: =flex的order
一、實現淘寶中這些條目的佈局
相似實現的代碼:
