父:

display:flex;

      父属性设置

  • flex-direction: row | row-reverse | column | column-reverse;

  • align-items:flex-start | flex-end | center | baseline | stretch;
  • align-content:flex-start | flex-end | center | space-between | space-around | stretch;

     子属性设置

  • order:number 越小越前
  • flex-grow :0 无变化  剩余长度按比例分配
  • flex-shrink:0 无变化   按比例缩小
  • 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;
    子元素上下的对其方式

 

css display:box 新属性 

https://www.cnblogs.com/whiteMu/p/5378747.html

一、display:box;

  在元素上设置该属性,可使其子代排列在同一水平上,类似display:inline-block;。

二、可在其子代设置如下属性

  前提:使用如下属性,必须在父代设置display:box;

  1.box-flex:number;

    1)占父级元素宽度的number份

    2)若子元素设置固定宽度,则该子元素应用固定宽度,其他未设置固定宽度的字元素将余下的父级宽度(父级-已设置固定宽度的子代元素的总宽度按 number占份数

    3)若子元素有margin值,则按余下(父级宽度-子代固定总宽度-总margin值)宽度占number份

  2.box-orient:horizontal/vertical

    在父级上设置该属性,则子代按水平排列或竖直排列。

    注:所有主流浏览器不支持该属性,必须加上前缀。

    1)horizontal  水平排列,子代总width=父级width。若父级固定宽度,则子代设置的width无效,子代会撑满父级宽度。

    2)vertical  垂直排列,子代总height=父级height。若父级固定高度,则子代设置的height无效,子代会撑满父级高度。

  3.box-direction:normal/reverse

    在父级上设置该属性,确认子代的排列顺序。

    1)normal  默认值,子代按html顺序排列

    2)reverse  反序

  4.box-align:start/end/center/stretch

    在父级设置,子代的垂直对齐方式。

    1)start  垂直顶部对齐

    2)end 垂直底部对齐

    3)center 垂直居中对齐

    4)stretch 拉伸子代的高度,与父级设置的高度一致。子代height无效。

  5.box-pack:start/end/center

    在父级设置,子代的水平对齐方式。

    1)start  水平左对齐

    2)end  水平右对齐

    3)center  水平居中对齐 

 

display:-ms-flexbox       https://msdn.microsoft.com/en-us/library/hh673531(v=vs.85).aspx

-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

 

1、实现淘宝中这些条目的布局

 

类似实现的代码:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        *{
            margin:0;padding:0;
        }
        html{font-size:32px;}
        .item-content{
            display: -webkit-box;
            display: -moz-box;
            display: -ms-flexbox;
            display: -webkit-flex;
            display: flex;
            -webkit-box-orient: vertical;
            -webkit-box-direction: normal;
            -moz-box-orient: vertical;
            -moz-box-direction: normal;
            -webkit-flex-direction: column;
            -ms-flex-direction: column;
            flex-direction: column;
            box-sizing: border-box;
            line-height: 0;
            width: 10rem;
            height: 4.594rem;
            background-color: rgb(255, 255, 255);
            margin:0 auto;
        }
        .item-small{
            display: -webkit-box;
            display: -moz-box;
            display: -ms-flexbox;
            display: -webkit-flex;
            display: flex;
            -webkit-box-orient: horizontal;
            -webkit-box-direction: normal;
            -moz-box-orient: horizontal;
            -moz-box-direction: normal;
            -webkit-flex-direction: row;

            flex-direction: row;
            box-sizing: border-box;
            line-height: 0;
            width:10rem;
            height:2rem;
            background-color: green;
        }
        .item{
            width:2rem;
            height:2rem;
            box-sizing: border-box;
            border:10px solid #fff;
        }
        .item:nth-child(odd){
            background-color:red;
        }
        .item:nth-child(even){
            background-color:green;
        }
    </style>
</head>
<body>
<div class="item-content">
    <div class="item-small">
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
    </div>
    <div class="item-small">

        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
    </div>
</div>
