 4   <view class='item'>3</view>
 5   <view class='item'>4</view>
 6   <view class='item'>5</view>

 8   <view class='item'>7</view>
 9   <view class='item'>8</view>
10   <view class='item'>9</view> -->

justify-items和justify-self指定网格项目沿着行轴对齐方式；align-items和align-self指定网格项目沿着列轴对齐方式。

justify-items和align-items应用在网格容器上，它们的属性值有：

auto
normal
start
end
center
stretch
baseline
first baseline
