微信小程序把玩（八）view组件

刚看到这个效果的时候还真是和ReactNative的效果一致，属性也基本的一样.
view这个组件就是一个视图组件使用起来非常简单。

主要属性：

flex-direction： 主要两个特性”row”横向排列”column”纵向排列

justify-content 主轴的对齐方式（如果flex-direction为row则主轴就是水平方向）

• 可选属性 (‘flex-start’, ‘flex-end’, ‘center’, ‘space-between’, ‘space-around’)

align-items 侧轴对齐方式如果flex-direction为row则侧轴就是垂直方向）

• 可选属性 (‘flex-start’, ‘flex-end’, ‘center’）
