<body>
<!--头部-->
<div class="header">flex圣杯布局+align-self, order的用法</div>
<!--主体-->
<div class="main">
<!--    左侧-->
    <div class="left">左侧
    本来是在左侧内容利用order属性使其排在右侧
        <br>

    </div>
<!--    中间-->
    <div class="center">中间</br>
        中间占据固定60%的空间flex-grow与flex-shrink属性采用默认值 。</br>
       左、右两则项目将占据固定20%的空间flex-grow与flex-shrink属性采用默认值 。

    </div>
    <!--    右侧-->
    <div class="right">右侧
        本来是在右侧的内容利用order属性使其排在左侧
    </div>
</div>
<!--底部-->
<div class="foot">
<div class="self">self1</div>
 <div class="self">self2</div>
 <div class="self">self3</div>
  <div class="self">self4</div>
    <div class="self">self5</div>
    <div class="self">self6</div>

    self1使用的是align-self:center:交叉轴的中点对齐。<br>
    self2使用的是align-self:flex-start;交叉轴的起点对齐。<br>
    self3使用的是align-self: flex-end;交叉轴的终点对齐<br>
    self4使用的是align-self:stretch(默认值):如果项目未设置高度或设为auto,将占满整个容器的高度<br>
    self5使用的是align-self: baseline;项目的第一行文字的基线对齐<br>
    self6使用的是align-self: auto;设为auto,将占满整个容器的高度
</div>

总结

课上讲得太细了反而还有点蒙,后面自己写写感觉还行,不是哪么的难,但还是需要多写多敲,
