Answer 1

使用vh作为高度的单位，这是后遗症，软键盘弹出后，整个页面高度发生变化。比如说，原来的视窗高度为1334px，那么14vh的高度就是1334 x 0.14 = 186.76(px) ； 小键盘弹出来后高度变为 800px, 那么14vh的高度只有 800 x 0.14 = 112(px)了；但是vw却没有改变，所以你看到的视图是变形的。
解决方案： 统一使用vw布局；

建议参考分享手淘过年项目中采用到的前端技术对vw进行兼容处理

Answer 2

我一般是这么设置

login:{
    min-height:100%;
}
一般都是页面被顶上去(IOS),你这还能出现页面被挤压
