css - CSS：仅在 Mac 上使用字体

Question

@font-face 很棒，但在 PC 上却显得很安静。只有在 Mac 上（不了解 linux）才能自然显示。如何仅为 mac 用户显示特殊字体并为 PC 用户回退到常规字体？

谢谢！

Answer 1

如果您不介意使用 JavaScript 和 jQuery，您可以使用jQuery 客户端插件检测操作系统，然后设置字体。它似乎是旧东西，但它适用于 jQuery 1.3.2，如果它适用于 jQuery 1.6.1，我不会感到惊讶。

<script src="./jquery-1.3.2.js"></script> 
<script src="./jquery.client.js"></script> 
<script type="text/javascript"> 
    if($.client.os == 'Mac')
        $('body').css('font-family',"'Looks good in Mac'")
    else if($.client.os == 'Windows')
        $('body').css('font-family',"'Looks good in Windows'")
    else if($.client.os == 'Linux')
        $('body').css('font-family',"'Looks good in Linux'")
</script> 

你可以body用任何 CSS 选择器替换，即使浏览器不支持，jQuery 也可能支持。

jQuery 可从 jquery.com 获得

满的jquery.client.js

jQuery 客户端插件非常酷。要至少使用纯 JavaScript 进行操作系统嗅探（我假设这会节省一些开销），您可以执行以下操作：

$(document).ready( function () {
    var os = navigator.platform;
    if (os.indexOf("Mac") != -1) {
        $('body').css( 'font-family', '"Lucida Grande"' );
    }
    else if (os.indexOf("Win") != -1) {
        $('body').css( 'font-family', '"Arial"' );
    }
    else if (os.indexOf("iPhone") != -1) {
        $('body').css( 'font-family', '"Helvetica"' );
    }
});

尽管我同意你关于 Windows 的看法，但恐怕你不能单独使用 CSS 来区分 Mac 浏览器和 Windows 浏览器。您需要使用服务器端脚本（或者可能是 JavaScript？）来嗅探它，并相应地决定是否加载@font-faceCSS。
