flex是网页布局方法中最实用的方法，简单，比较适合移动端网页布局，它只有父级/flex容器和子级/flex项目两个元素。它是一维布局，主轴只有一个，要么横向要么纵向，代表着排列方式只有一个。

flex容器的6个属性和功能如下


6个属性和功能实例如下：

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4.     <meta charset="UTF-8">
  5.     <title>flex</title>
  6.     <style>
  7.         .container{
  8.             border: 1px dashed;
  9.             box-sizing: border-box;
  10.             background-color: lightskyblue;
  11.         }
  12.         .item{
  13.             width: 100px;
  14.             height: 50px;
  15.             border: 1px dashed;
  16.             background-color: wheat;
  17.             margin:  1px;
  19.         }
  20.         .container{
  21.             /*转为flex容器*/
  22.             display: flex;
  23.         }
  24.         .container{
  25.             flex-direction: column;
  26.             /*flex-wrap: ;*/
  27.             /*flex-flow: ;*/
  28.             /*justify-content: ;*/
  29.             align-items: center;
  30.             /*align-content: ;*/
  31.         }
  33.     </style>
  34. </head>
  35. <body>
  36. <div class="container">
  37.     <div class="item">1</div>
  38.     <div class="item">2</div>
  39.     <div class="item">3</div>
  40.     <div class="item">4</div>
  41.     <div class="item">5</div>
  42.     <div class="item">6</div>
  43.     <div class="item">7</div>
  44.     <div class="item">8</div>
  45. </div>
  46. </body>
  47. </html>

实现了居中垂直布局

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4.     <meta charset="UTF-8">
  5.     <title>flex</title>
  6.     <style>
  7.         .container{
  8.             border: 1px dashed;
  9.             box-sizing: border-box;
  10.             background-color: lightskyblue;
  11.             width: 300px;
  12.             height: 800px;
  13.         }
  14.         .item{
  15.             width: 100px;
  16.             height: 50px;
  17.             border: 1px dashed;
  18.             background-color: wheat;
  19.             margin:  1px;
  21.         }
  22.         .container{
  23.             /*转为flex容器*/
  24.             display: flex;
  25.         }
  26.         .container{
  27.             /*flex-direction: column;*/
  28.             /*flex-wrap: ;*/
  29.             flex-flow: row wrap;
  30.             justify-content: center;
  31.             /*align-items: center;*/
  32.             align-content:space-between ;
  33.         }
  35.     </style>
  36. </head>
  37. <body>
  38. <div class="container">
  39.     <div class="item">1</div>
  40.     <div class="item">2</div>
  41.     <div class="item">3</div>
  42.     <div class="item">4</div>
  43.     <div class="item">5</div>
  44.     <div class="item">6</div>
  45.     <div class="item">7</div>
  46.     <div class="item">8</div>
  47. </div>
  48. </body>
  49. </html>


实现了多行居中水平排列上下平均布局

flex的6个属性包分为设置主轴，交叉轴和换行三类
row代表为横向，column代表纵向，reverse代表反向
wrap为分行，nowrap代表不分行，当使用nowrap时，如果容器大小不够，项目会相对缩小

对齐方式有：center、left、right、space-between、space-evently、space-around等
12.20作业心得
这次作业由于种种原因，可以说是老师手把手带着写的，对于float的概念比较差，即使是课后也是看回放才对float的使用有了一个认识，学会了如何在html中调用css，对于我自己而言，现阶段是处于一个听得懂看得懂但是不会用的情况，这需要在平常多挤出时间来进行实际操作，BETTER TO GO THEN CURSE THE ROAD
