A lead paragraph goes here.

This is what shows up in post listings and in social preview cards, so make it stand on its own — one to three sentences that frame what the reader is about to get.

A section heading

Body text inherits the site’s typography: Source Serif 4 at 16px on a 1.6 line-height. Inline emphasis like bold, italic, and inline code follows the same family, with code switching to JetBrains Mono. Links look like this and open in a new tab when external.

A sub-section

Heading hierarchy follows a perfect-fourth scale (1.333×) on desktop and a major-third scale (1.25×) on mobile. h2 marks sections, h3 marks sub-sections. You shouldn’t normally need h4 or deeper — if you do, it’s a sign the post should split.

A bulleted list:

  • First point
  • Second point with a link
  • Third point

A numbered list when order matters:

  1. First step
  2. Second step
  3. Third step

A blockquote sets off a quotation or an aside. Use it sparingly — for citations, key claims, or a voice that isn’t yours.

Code

Inline code: let x = 42;. Fenced blocks get syntax highlighting via Rouge:

def fibonacci(n):
    a, b = 0, 1
    for _ in range(n):
        a, b = b, a + b
    return a

Math

Inline math like $E = mc^2$ flows naturally with the prose. Display math sits on its own line, centered:

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

Aligned environments work too:

\[\begin{aligned} \nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\ \nabla \cdot \mathbf{B} &= 0 \end{aligned}\]

Images

Drop images in assets/images/posts/ and reference them like this (uncomment when ready):

Always include alt text — it’s both an accessibility requirement and what screen readers and search engines actually read.

Footnotes

A claim that needs sourcing can carry a footnote.1 Footnotes collect at the bottom of the post automatically.

Tables

Method Convergence Cost
Newton quadratic high
Secant superlinear medium
Bisection linear low

Tables wrap in a horizontal scroll container on mobile automatically.

  1. Footnote text appears at the bottom of the post, with a back-link to the reference. ↩
