Full Feature Demonstration

14 March 2026

This page demonstrates the Markdown and Quarto features supported by this Astro site.

This page restores the old feature-tour structure, but updates each example to the Quarto syntax that now powers src/pages/posts/*.md.

1 Headers

The Astro layout owns the page title, so the visible page <h1> is the post title above this content. Inside the Markdown body, Quarto top-level sections still start with #, but they render one level below that page title.

1.1 This is a Heading h2

1.1.1 This is a Heading h3

1.1.1.1 This is a Heading h4

2 Formatting

This text will be italic.

This text will be bold.

You can combine them.

2.1 Blocks of Code

let message = "Hello world";
alert(message);

2.2 Inline Code

This web site is using markedjs/marked as an example of inline code formatting.

2.3 Blockquotes

Blockquotes are supported with the standard > syntax.

Nested blockquotes are also supported.

5 Equations

Display math is labeled reliably in this site with trailing Quarto ids.

Equation labeled after the block:

E=mc2(5.1) E = mc^2 \qquad(5.1)

Reference: Equation 5.1.

A second labeled equation:

∇×𝐄=−∂𝐁∂t(5.2) \nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t} \qquad(5.2)

Reference: Equation 5.2.

6 Tables

Tables use the standard Pandoc/Quarto caption paragraph syntax : Caption {#tbl-label}.

Element Symbol Electrons
Hydrogen H 1
Helium He 2
Table 6.1: Periodic table excerpt
