This post is a compact test page for common Markdown features, LaTeX rendering, syntax highlighting, and mixed HTML content.

Paragraphs and inline formatting

This is a paragraph with bold text, italic text, bold italic text, ~~strikethrough text~~, inline code, and a keyboard shortcut: Ctrl + K.

Markdown can also include links like Jekyll, automatic URLs like https://example.com, and email links like hello@example.com.

Use inline HTML when needed: highlighted text, ^superscript, _subscript, and HTML.

Blockquotes

This is a blockquote.

It can span multiple paragraphs and include formatting.

Nested blockquotes should also render clearly.

Code

Inline code looks like const answer = 42.

function fibonacci(n) {
  if (n < 2) return n;
  return fibonacci(n - 1) + fibonacci(n - 2);
}

console.log(fibonacci(8));

LaTeX

Inline math should render inside text, such as $E = mc^2$, $a^2 + b^2 = c^2$, and $\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$.

Block math:

\[\int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}\]

Aligned equations:

\[\begin{aligned} \nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\ \nabla \cdot \mathbf{B} &= 0 \\ \nabla \times \mathbf{E} &= -\frac{\partial \mathbf{B}}{\partial t} \\ \nabla \times \mathbf{B} &= \mu_0 \mathbf{J} + \mu_0\varepsilon_0\frac{\partial \mathbf{E}}{\partial t} \end{aligned}\]

Matrix notation:

\[A = \begin{bmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{bmatrix}\]
