添加 mathjax

定位到themes\PaperMod\layouts\partials,创建mathjax.html并编辑:

<script type="text/javascript"
        async
        src="https://cdn.bootcss.com/mathjax/2.7.3/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
MathJax.Hub.Config({
  tex2jax: {
    inlineMath: [['$','$'], ['\\(','\\)']],
    displayMath: [['$$','$$'], ['\[\[','\]\]']],
    processEscapes: true,
    processEnvironments: true,
    skipTags: ['script', 'noscript', 'style', 'textarea', 'pre'],
    TeX: { equationNumbers: { autoNumber: "AMS" },
         extensions: ["AMSmath.js", "AMSsymbols.js"] }
  }
});

MathJax.Hub.Queue(function() {
    // Fix <code> tags after MathJax finishes running. This is a
    // hack to overcome a shortcoming of Markdown. Discussion at
    // https://github.com/mojombo/jekyll/issues/199
    var all = MathJax.Hub.getAllJax(), i;
    for(i = 0; i < all.length; i += 1) {
        all[i].SourceElement().parentNode.className += ' has-jax';
    }
});
</script>

<style>
code.has-jax {
    font: inherit;
    font-size: 100%;
    background: inherit;
    border: inherit;
    color: #515151;
}
</style>

编辑 extend_head

定位到themes\PaperMod\layouts\partials\extend_head.html,添加以下代码:

{{ partial "mathjax.html" . }}

LaTeX 效果展示

  • 先试试行内公式 $$ x^2 +1 = 0 $$
  • 再试试行间公式

$$ \begin{equation} \begin{split} (a + b)^3 &= (a + b)(a + b)^2 \\ &= (a + b)(a^2 + 2ab + b^2) \\ &= a^3 + 3a^2b + 3ab^2 + b^3 \end{split} \end{equation} $$
