个人作品集网站加载时出现字体及样式闪烁问题求助

问题：网站加载时字体及样式出现短暂闪烁

我制作的个人作品集网站，在不同浏览器中打开时，字体及其他样式会先显示为非预期状态，1-2秒后才刷新为预设样式。当前使用DreamHost作为主机服务商，不确定该问题是否与服务商有关。

解决方案

1. 优化字体加载，消除字体闪烁

确保Google Fonts链接启用font-display: swap，让浏览器先显示系统默认字体，自定义字体加载完成后再替换，避免空白或样式突变。你的链接已包含display=swap，若仍有问题可显式指定：
```
<link href="https://fonts.googleapis.com/css2?family=Caveat:wght@400;700&display=swap&font-display=swap" rel="stylesheet">
```

添加字体加载监听，在字体就绪后切换样式：
先给body设置降级字体：

body {
  font-family: sans-serif, 'Caveat', cursive;
}

再在JS中添加监听：

document.fonts.ready.then(() => {
  document.body.style.fontFamily = "'Caveat', cursive";
});

2. 加速CSS加载，避免样式延迟

将关键CSS（如body、nav、静态左侧栏的基础样式）内联到HTML头部，减少外部CSS加载等待时间：

<head>
  <!-- 其他meta和link -->
  <style>
    * { margin:0; padding:0; box-sizing:border-box; }
    body { font-family: sans-serif, 'Caveat', cursive; background:white; color:black; }
    nav { position:fixed; top:0; right:20px; background:white; z-index:1000; }
    .static-left { position:fixed; left:0; top:0; width:30%; height:100vh; background:white; padding:20px; border-right:1px solid #ddd; }
  </style>
</head>

用preload预加载关键资源：

<link rel="preload" href="style.css" as="style">
<link rel="preload" href="https://fonts.googleapis.com/css2?family=Caveat:wght@400;700&display=swap" as="style">

3. 优化动态内容的布局稳定性

给项目列表添加占位样式，避免加载完成后布局跳动：

#project-list .placeholder {
  padding:20px;
  border:1px solid #ddd;
  border-radius:10px;
  background:#f9f9f9;
  font-size:1.4rem;
  color:#666;
}

修改HTML中的占位文本：

<div id="project-list">
  <div class="placeholder">Projects will be dynamically loaded here...</div>
</div>

4. 静态资源缓存配置（针对DreamHost）

DreamHost本身不会导致这类问题，但可通过.htaccess添加缓存头加速静态资源重复加载：

<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresByType text/css "access plus 1 month"
  ExpiresByType application/font-woff2 "access plus 1 year"
  ExpiresByType image/jpeg "access plus 1 month"
  ExpiresByType image/png "access plus 1 month"
</IfModule>
