justify-self 属性，
    设置单元格内容的水平位置（左中右），跟justify-items属性的用法完全一致，但只作用于单个项目。
align-self 属性，
    属性设置单元格内容的垂直位置（上中下），跟align-items属性的用法完全一致，也是只作用于单个项目。

      start：对齐单元格的起始边缘。
      end：对齐单元格的结束边缘。
      center：单元格内部居中。
      stretch：拉伸，占满单元格的整个宽度（默认值）。

  .item {
    justify-self: start | end | center | stretch;
    align-self: start | end | center | stretch;
  }


place-self 属性
    属性是align-self属性和justify-self属性的合并简写形式

      place-self: &lt;align-self&gt; &lt;justify-self&gt;;
