媒体查询适配不同移动端屏幕尺寸大小
1、使用media的时候需要先设置<meta>标签来兼容移动设备的展示。
<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
width=device-width :宽度等于当前设备的宽度
user-scalable=no:用户是否可以手动缩放(默认设置为no,不允许用户放大缩小页面)
initial-scale=1:初始的缩放比例(默认设置为1.0)
minimum-scale=1:允许用户缩放到的最小比例(默认设置为1.0)
maximum-scale=1:允许用户缩放到的最大比例(默认设置为1.0)
2、设置如:当屏幕宽度在375px~383px时,100px=1rem,写样式时把px单位换算成rem
