谷歌AJAX Libraries API，包括jQuery UI(目前v1.10.3)，也包括流行的主题，根据jQuery UI博客:

jQuery现在有一个CDN访问:

code.jquery.com/ui/[版本]/主题/[主题名称]/jquery-ui.css

为了让这更简单一点，给你:

谷歌是托管jQueryUI css在这个链接https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.all.css

如果你直接看这段代码，它正在使用@import导入css，这可能会很慢。您可能希望将导入分解到各个部分中，以获得轻微的性能优势:

https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.base.css https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.theme.css

我想是的。为什么不呢?如果不提供CSS来支持脚本文件，就不是一个CDN

这种联系表明它们是:

我们发现特别令人兴奋的是 jQuery UI CSS主题现在 托管在谷歌的Ajax Libraries CDN上。

jQuery UI < 1.13被谷歌Page Speed Insights认为是一个安全漏洞。

请使用安全修复的最新版本。到2022年，这将是1.13.2

Ex:

https://ajax.googleapis.com/ajax/libs/jqueryui/1.13.2/jquery-ui.min.js https://ajax.googleapis.com/ajax/libs/jqueryui/1.13.2/themes/smoothness/jquery-ui.min.css

完整的HTML标签示例:

<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.13.2/themes/smoothness/jquery-ui.css">
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.13.2/jquery-ui.min.js"></script>

如果你指的是jQuery UI css，你可以使用这个:

<link rel="stylesheet" type="text/css" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
