使用javascript数学渲染库是目前在html中显示数学公式的最推荐方案，因为它具备良好的跨浏览器兼容性和强大的功能支持；具体实现时可选择mathjax或katex，其中mathjax功能全面、支持复杂公式和可访问性，适合学术类网站，通过引入cdn链接并使用latex语法（如$e=mc^2$或$$...$$）即可渲染行内或独立公式，而katex则以轻量和高速著称，适合对性能要求较高的场景，两者均需在html中引入相应js和css文件后，用特定符号包裹公式内容，由库自动解析并展示，因此使用javascript库能有效确保数学公式在网页上的准确与美观呈现。

HTML如何显示数学公式？MathML怎么嵌入网页？

在HTML中显示数学公式，通常我们有几个主流选择：要么依赖像MathJax或KaTeX这样的JavaScript库来解析LaTeX风格的数学表达式并将其渲染出来，要么直接嵌入MathML（数学标记语言）。对于大多数现代网页，JavaScript库因其出色的跨浏览器兼容性和强大的功能集，往往是更稳妥、更受欢迎的方案。而MathML，虽然是W3C的标准，旨在提供原生的语义化数学内容，但其在不同浏览器间的支持情况曾一度不尽如人意，即便现在有所改善，也常需配合库来确保一致性。

解决方案

要让数学公式在网页上活起来，我个人觉得，最省心也最强大的方案，目前来看还是使用JavaScript渲染库。这就像你想要在网页上播放视频，你可以选择直接用HTML5的

这是目前最主流也最可靠的方法。这些库通常会解析你在HTML中用特定语法（最常见的是LaTeX）编写的数学公式，然后将其转换为浏览器能够良好显示的格式，比如MathJax可以渲染成MathML、SVG或HTML-CSS，而KaTeX则主要渲染成HTML-CSS。

MathJax：这是一个非常成熟且功能丰富的库。它几乎支持所有LaTeX的数学语法，并且在可访问性方面做得很好。
- 如何使用：你需要在HTML的

  部分引入MathJax的CDN链接。

- 编写公式：然后，你就可以在你的HTML内容中直接用LaTeX语法写公式了。MathJax会扫描页面，找到这些公式并进行渲染。
  - 行内公式（inline）：用

- 我的看法：MathJax功能确实强大，对复杂公式和各种符号的支持无懈可击，但相对来说，它的文件体积稍大，首次加载可能会有一点点延迟。不过对于学术或技术内容网站，这点牺牲完全值得。

KaTeX：如果你追求极致的渲染速度和轻量级，KaTeX是个不错的选择。它由Khan Academy开发，渲染速度非常快，因为它不需要额外的字体文件，并且是同步渲染。

如何使用：同样，在
