尽管它们都在 CSS 中，但浏览器不会对每个 webfont 发出请求

Question

我正在为 Jekyll使用午夜主题。Jekyll 目前是 v3.7.4

我的主题是指捆绑的 OpenSans webfont，我还添加了 FontAwesome。但是浏览器只会请求 OpenSans 字体，而不会请求 FontAwesome 文件。

在我的页面的头部（编译）：

  <!-- theme -->
  <link rel="stylesheet" href="/assets/css/style.css?v=e16a158">
  <!-- theme overrides -->
  <link rel="stylesheet" href="/assets/css/hello.css?v=e16a158">

未编译：

  <!-- theme -->
  <link rel="stylesheet" href="{{ '/assets/css/style.css?v=' | append: site.data['hash'] | relative_url }}">
  <!-- theme overrides -->
  <link rel="stylesheet" href="{{ '/assets/css/hello.css?v=' | append: site.data['hash'] | relative_url }}">

hello.scss是我自定义样式的地方。前两行是根据FontAwesome 说明：

---
---
@import "./vendor/fontawesome/fontawesome.scss";
@import "./vendor/fontawesome/brands.scss";

编译后的 CSS（位于/assets/css）包括：

@charset "UTF-8";
/*!
 * Font Awesome Free 5.13.0 by @fontawesome - https://fontawesome.com
 * License - https://fontawesome.com/license/free (Icons: CC BY 4.0, Fonts: SIL OFL 1.1, Code: MIT License)
 */

@font-face {
  font-family: 'Font Awesome 5 Brands';
  font-style: normal;
  font-weight: 400;
  font-display: block;
  src: url("../fonts/fa-brands-400.eot");
  src: url("../fonts/fa-brands-400.eot?#iefix") format("embedded-opentype"), url("../fonts/fa-brands-400.woff2") format("woff2"), url("../fonts/fa-brands-400.woff") format("woff"), url("../fonts/fa-brands-400.ttf") format("truetype"), url("../fonts/fa-brands-400.svg#fontawesome") format("svg"); }
.fab {
  font-family: 'Font Awesome 5 Brands';
  font-weight: 400; }

获取/assets/fonts/fa-brands-400.woff工作：

$ http :8888/assets/fonts/fa-brands-400.woff

然而，当我在任何浏览器中访问该站点时（尝试过 Firefox、Linux 上的 Chrome 和 iOS 上的 Safari），它甚至不会尝试请求 FontAwesome 字体文件：

有趣的是，OpenSans 字体文件在编译的 CSS 中是这样引用的，浏览器可以启动请求：

@font-face {
  font-family: 'OpenSansLight';
  src: url("../fonts/OpenSans-Light-webfont.eot");

到底是怎么回事？当 OpenSans 工作正常时，为什么我不能让浏览器甚至请求 FontAwesome 字体文件？

Answer 1

我单击了此链接：https://5e9c012d3f93e40006beb655--hello-64bit.netlify.app/

您的 HTML（第 71 行）内容如下：

<i class="fa fa-twitter"></i>

你的 hello.css （已解析，第 4512 行）内容如下：

.fab {
  font-family:'Font Awesome 5 Brands';
  font-weight:400
} 

显然你需要将第 71 行更改为：

<i class="fab fa-twitter"></i>

快乐编码！
