我的网站有手机css和桌面Css我已经包含了
<link rel="stylesheet" type="text/css" media="only screen and (max-width: 1320px)" href="styles/responsive-grid/small-desktop.css" />
<link rel="stylesheet" type="text/css" media="only screen and (max-width: 990px)" href="styles/responsive-grid/tablet.css" />
<link rel="stylesheet" type="text/css" media="only screen and (max-width: 660px)" href="styles/responsive-grid/mobile.css" />
<link rel="stylesheet" type="text/css" media="only screen and (max-width: 990px)" href="styles/tablet.css" />
<link rel="stylesheet" type="text/css" media="only screen and (max-width: 660px)" href="styles/mobile.css" />
这很好但是 我需要仅在桌面上包含桌面css，仅在移动设备上包含Mobile Css以减少请求
