css媒体查询有一个 宽高比很方便,aspect-ratio ,可以直接使用宽/高 来进行页面适配 使用样例如下:
- // 宽高比在((320/50)+(728/90))/2 两个尺寸中间值以内 适配 320*50 设计图样式
- @media screen and (min-aspect-ratio: ~"249/50") and (max-aspect-ratio: ~"29/4"){
- @base: 320;
- @convert: 375/@base;

注意三点:
1、宽高比一定是比值的形式,不能直接写小数,宽/高
2、在less中直接写宽高比也不会生效,因为less会编译成小数,可以在比值前面加一个 ~ 完美解决
3、避免样式覆盖,最好把大比例的媒体查询写在后面
