您好，我正在使用多个平板设备、iPad、Galaxy Tab、Acer Iconia、LG 3D Pad 等。
我只想使用 CSS3 媒体查询定位 iPad。因为，LG 和 iPad 的设备宽度是相同的 768px - 我无法分离每个设备。
我试过按照以下方式分开，但似乎没有用：
@media only screen and (min-device-width: 768px) and (max-device-width: 1024px) and (orientation : portrait) /* applied to lg also */
@media only screen and (min-resolution: 132dpi) and (max-device-width: 1024px) and (orientation : portrait) /* applies to lg also */
@media only screen and (device-aspect-ratio: 1024/768) and (orientation : portrait) /* does not work on iPad or LG */
我不知道 -webkit-device-pixel-ratio 和其他 -webkit* 选项及其针对 iPad 的值。我不想将 JavaScript 用于样式，有什么想法吗？
终于找到解决方案：Detect different device platforms using CSS
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait)" href="ipad-portrait.css" />
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:landscape)" href="ipad-landscape.css" />
为了减少 HTTP 调用，这也可以在您现有的通用 CSS 文件中使用：
@media all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait) {
.ipad-portrait { color: red; } /* your css rules for ipad portrait */
}
@media all and (device-width: 1024px) and (device-height: 768px) and (orientation:landscape) {
.ipad-landscape { color: blue; } /* your css rules for ipad landscape */
}
其他参考：
我回答这个问题有点晚了，但以上都不适合我。
这对我有用
@media only screen and (min-device-width: 768px) and (max-device-width: 1024px) {
//your styles here
}
您需要使用一些脚本通过其用户代理来定位设备。 iPad 的用户代理是：
Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10
完全相同的问题，也有答案 =)

@media only screen and (device-width: 768px) ...
@media only screen and (max-device-width: 1024px) ...
我目前无法测试所以请测试它=）
还发现了一些：

或者您使用一些 javascript 检查导航器并使用 javascript 生成/添加一个 css 文件

如今，您可以使用 Media Queries Level 4 功能来检查设备是否具有 “悬停”在元素上 的能力。
@media (hover: hover) { ... }
由于 ipad 没有“悬停”状态，您可以有效地定位像 ipad 这样的触摸设备。
/*working only in ipad portrait device*/
@media only screen and (width: 768px) and (height: 1024px) and (orientation:portrait) {
body{
background: red !important;
}
}
/*working only in ipad landscape device*/
@media all and (width: 1024px) and (height: 768px) and (orientation:landscape){
body{
background: green !important;
}
}
In the media query of specific devices, please use '!important' keyword to override the default CSS. Otherwise that does not change your webpage view on that particular devices.
这是 ipad
@media all and (device-width: 768px) {
}
这是为 ipad pro 设计的
@media all and (device-width: 1024px){
}
针对 iPad 9 和 iPad 10 的 CSS：
/* iPad 9th Gen */
@media only screen
and (min-device-width: 810px)
and (max-device-width: 1080px)
and (min-device-pixel-ratio: 2) {
/* rules here */
}
/* iPad 10th Gen */
@media only screen
and (min-device-pixel-ratio: 2) {
/* rules here */
}
