Writing Theorems, Proofs, and Definitions on Dev.to

If you're writing a math-heavy article — explaining an algorithm's correctness, proving a complexity bound, or walking through a cryptographic protocol — you need a way to clearly distinguish theorems, proofs, definitions, and examples from the surrounding text. Standard LaTeX has dedicated environments for this ( \begin{theorem} , \begin{proof} ). Dev.to doesn't. But with some markdown techniques, you can get close. Method 1: Blockquotes (Simplest) Markdown blockquotes ( > ) give a visual distinction from body text: > **Theorem 1 (Lagrange's Theorem).** > For a finite group G and subgroup H, > the order of H divides the order of G: > {% katex %} |G| = [G : H] \cdot |H| {% endkatex %} Theorem 1 (Lagrange's Theorem). For a finite group G and subgroup H, the order of H divides the order of G: ∣G∣=[G:H]⋅∣H∣|G| = [G : H] \cdot |H| ∣ G ∣ = [ G : H ] ⋅ ∣ H ∣ Simple, reliable, and works everywhere. Method 2: Collapsible Proofs Long proofs can overwhelm readers. Use <details> to make them coll
