您如何为多种屏幕尺寸编写媒体查询？

Question

如果我想

body {font-size:18 px} 1900年及以上

body {font-size:16 px} 对于1024和1900

body {font-size:14 px} 为768到1023

body {font-size:12 px} 为320到767

body {font-size:11 px} 为0到320

我刚才给出了问题的例子.

Answer 1

这应该做的工作

@media only screen and (min-width: 320px)  { body{ font-size: 12px; } }
@media only screen and (min-width: 768px)  { body{ font-size: 14px; } }
@media only screen and (min-width: 1024px) { body{ font-size: 16px; } }
@media only screen and (min-width: 1900px) { body{ font-size: 18px; } }
