This document demonstrates how to use LaTeX equations in your Markdown files for astro-minimax. LaTeX is a powerful typesetting system often used for mathematical and scientific documents.
Instructions
In this section, you will find instructions on how to add support for LaTeX in your Markdown files for astro-minimax.
-
Install the necessary remark and rehype plugins by running:
bashpnpm install rehype-katex remark-math katex -
Update the Astro configuration to use the these plugins:
ts// ... import remarkMath from "remark-math"; import rehypeKatex from "rehype-katex";
export default defineConfig({ // … markdown: { remarkPlugins: [ remarkMath, // [!code ++] ], rehypePlugins: [rehypeKatex], // [!code ++] shikiConfig: { // For more themes, visit https://shiki.style/themes themes: { light: “min-light”, dark: “night-owl” }, wrap: false, }, }, // … });
3. Import KaTeX CSS in the main layout file
```astro file=src/layouts/Layout.astro
---
import { SITE } from "@config";
// astro code
---
<!doctype html>
<!-- Other elements -->
<meta property="og:image" content={socialImageURL} />
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/katex@0.15.2/dist/katex.min.css"
/>
<body>
<slot />
</body>-
As the last step, add a text-color for
katexintypography.css.
css@plugin "@tailwindcss/typography"; @layer base { /* other classes */ /* Katex text color */ .prose .katex-display { @apply text-foreground; } /* ===== Code Blocks & Syntax Highlighting ===== */ /* other classes */ }
And voilà, this setup allows you to write LaTeX equations in your Markdown files, which will be rendered properly when the site is built. Once you do it, the rest of the document will appear rendered correctly.
Inline Equations
Inline equations are written between single dollar signs $...$. Here are some examples:
- The famous mass-energy equivalence formula:
$E = mc^2$ - The quadratic formula:
$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ - Euler’s identity:
$e^{i\pi} + 1 = 0$
Block Equations
For more complex equations or when you want the equation to be displayed on its own line, use double dollar signs $$...$$:
The Gaussian integral:
$$ \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi} $$The definition of the Riemann zeta function:
$$ \zeta(s) = \sum_{n=1}^{\infty} \frac{1}{n^s} $$Maxwell’s equations in differential form:
$$
\begin{aligned}
\nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\
\nabla \cdot \mathbf{B} &= 0 \\
\nabla \times \mathbf{E} &= -\frac{\partial \mathbf{B}}{\partial t} \\
\nabla \times \mathbf{B} &= \mu_0\left(\mathbf{J} + \varepsilon_0 \frac{\partial \mathbf{E}}{\partial t}\right)
\end{aligned}
$$Using Mathematical Symbols
LaTeX provides a wide range of mathematical symbols:
- Greek letters:
$\alpha$,$\beta$,$\gamma$,$\delta$,$\epsilon$,$\pi$ - Operators:
$\sum$,$\prod$,$\int$,$\partial$,$\nabla$ - Relations:
$\leq$,$\geq$,$\approx$,$\sim$,$\propto$ - Logical symbols:
$\forall$,$\exists$,$\neg$,$\wedge$,$\vee$
