html - 网站加载缓慢！是因为我的 CSS 吗？

Question

我不知道为什么，但是我的网站加载速度很慢...我怀疑我的 .css 存在问题，因为当我从 .css 中删除徽标的背景 url 并使用 index.html 时，您现在可以看到它快速加载（仅限徽标)

这是我的网站网址

这是我的 main.css 文件

您的网站出现缓慢有几个原因。

自定义字体似乎只有在页面加载后才会下载。在加载字体文件之前，页面上使用 @font-face 定义声明的字体的任何元素都不会显示。这就是为什么您的网站似乎长时间“无法加载”的原因。

我不熟悉浏览器如何优先考虑 CSS 文件中声明的字体的下载顺序 - 或者是否有办法强制首先下载它们。但是，使用 chromes 开发人员工具，看起来字体文件直到 DOMContent 事件被触发才被下载，然后它们被串行下载而不是并行下载。

此外，正如您所注意到的，删除背景会加快页面速度。您的背景文件超过 1MB，这对于网站来说是相当可观的。如果图像尺寸较小，它将下载并显示得更快。

如果您只是删除自定义字体，我相信您会看到巨大的改进。
