我的代码使用此代码
<iframe width="100%" height="100%" src="https://www.youtube.com/embed/vodID" title="VOD" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
和此代码
@font-face {
font-family: 'font name';
font-style: normal;
font-weight: 300;
src: url(./fonts/file location) format('woff2'),
url(./fonts/file location) format('woff'),
url(./fonts/file location) format('opentype');}
此代码花费很长的加载时间（在webpagetest.org中）
我该如何改善？

关于字体（我不确定这里的知识），但是也许您设置了“错误的设置，这意味着您包括了不需要的其他字符。根据许可证的不同，您可以选择字体并进行清洁它是由不必要的字符组成的，但这很讨厌您实际上不必这样做。
