How to Use LaTeX in HTML Tags for Math, Physics, and Chemistry

Embed LaTeX with KaTeX in HTML tags to display math formulas, physics equations, or chemical reactions on your website. Below are 4 essential methods for math blogs, educational websites, or science tutorials, with copyable code boxes. Use latex and math classes for KaTeX rendering.

Using <div>: For standalone math equations.

<div class="latex" style="visibility:hidden;">
  <div class="math n12">\int_0^1 x^2 \, dx</div>
</div>

Using <span>: For embedding physics equations in text.

<span class="latex" style="visibility:hidden;">
  <span class="math n12">E = mc^2</span>
</span>

Using <ol> <li>: For listing chemical reactions.

<ol class="latex" style="visibility:hidden;">
  <li><span class="math n12">\ce{2H2 + O2 -> 2H2O}</span></li>
</ol>

Using <p>: For math equations in paragraphs.

<p class="latex" style="visibility:hidden;">
  The quadratic formula is <span class="math n12">x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}</span>. It is used...
</p>

Note: Use visibility:hidden in the latex class to hide raw LaTeX before rendering. Adjust math nX (X from 1 to 20) for font size. Add KaTeX libraries to your template for rendering.

Advanced LaTeX FAQ

How do I generate LaTeX code for integrals?

Use an AI tool or LaTeX generator like Overleaf. For example, prompt an AI with: “Write LaTeX for the integral of x^2 dx” to get \int x^2 \, dx. Paste this into the <div class="math"> container for rendering.

Can AI tools generate physics equations in LaTeX?

Yes, AI tools like ChatGPT or Grok can convert physics equations into LaTeX. For example, ask: “Give LaTeX for Newton’s second law” to get F = ma. Use this code in your blog post’s <div class="math"> for display.

How can I display chemistry reactions using LaTeX?

With the KaTeX mhchem extension, you can render chemical equations. Prompt an AI with: “LaTeX for water formation reaction” to get \ce{H2 + O2 -> H2O}. Insert this into the <div class="math"> container in your post.

Why is visibility:hidden used in the LaTeX div?

The visibility:hidden style prevents raw LaTeX code from appearing on the page before KaTeX renders it. The JavaScript then sets visibility:visible after rendering, ensuring a smooth display of formatted equations.

How do I adjust the font size of LaTeX equations?

Use the n1 to n20 classes in the <div class="math"> container. For example, <div class="math n12"> sets a 12px font size on mobile devices (max-width: 550px). Adjust the class based on your equation’s length for optimal display.
