javascript - 无法弄清楚为什么我的网站加载如此慢

我从我的 html 老师那里得到了一个网站，他要求我检查它并修复存在的任何问题。虽然我修复了一些问题，但仍然有一个大问题我无法弄清楚。完全加载网站需要很长时间(大约 30 秒)。一切都正确加载，包括导航菜单和 YouTube 视频。我找到了问题的根源，它与JavaScript代码有关。我不懂JavaScripy，所以我无法弄清楚问题所在。当我删除 JavaScript 代码时，网站会加载，但导航菜单和视频不会加载，确切地说根本不加载。还有另一个 JavaScript 文件，但我认为它与此没有任何关系，而且在这里发布的时间太长，因此您可以下载文件 here 。 Here 是 css 文件。

最后 10 行 JavaScript 代码是问题所在。这是代码:

最佳答案

如果您有很多导入，请检查您的 style.css。这可能会导致加载时间过长。否则，如果您在本地托管它，请尝试将其移动到其他地方。或者检查你是否有很多动画(js)。

编辑:实际上，我这边的页面加载速度非常快。我的意思是我没有 CSS，但看起来它不是 html/js 代码。您能否将 CSS 代码也发布到您的问题中？
