Verto renders math at build time using remark-math and rehype-katex. KaTeX produces semantic HTML with the katex.min.css stylesheet — no client-side rendering, no flash.

Inline Math

Wrap expressions in single dollar signs: $\alpha + \beta = \gamma$ becomes $α + β = γ$ .

You can drop math anywhere in a paragraph — Euler's identity is $e^{iπ} + 1 = 0$ , the golden ratio is $φ = \frac{1 + 5}{2}$ , and so on.

Block Math

Use double dollar signs ($$ … $$) for centred, displayed equations.

\int_{- \infty}^{\infty} e^{- x^{2}} d x = π

Multi-line aligned equations use the standard aligned environment:

(a + b)^{2} (a - b)^{2} a^{2} - b^{2} = a^{2} + 2 ab + b^{2} = a^{2} - 2 ab + b^{2} = (a + b) (a - b)

Matrices

A = 147258369

Sums and Products

n = 1 \sum \infty \frac{1}{n ^{2}} = \frac{π ^{2}}{6} n = 1 \prod N n = N!

Resilience

Bad formulas don't crash the page render — they're rendered with KaTeX's built-in error styling so you can spot the typo in a draft.
