1Formatting#

1.1Ordinary Text#

Here is bold text, here is emphasised text, here is italic text, here is underlined text, and here is small caps. Typography should be converted: “curly quotes” around a phrase, an em-dash like this—using three minus signs—and an en-dash in a range such as pages 10–20. A tilde makes a non-breaking space, as in Figure 1.

Native handling for links is handled. Here is an inline link with custom text, and here is a bare one: https://example.org. A relative link points back at the notes, and a link that sends mail works too: send mail.

1.2Lists#

An unordered list:

The first item, which is short.
The second item, which is deliberately long to wrap onto a second line so that hanging indentation can be checked properly.
The third item, containing bold and a link to somewhere else.

An ordered list, including a nested one:

First numbered item.
Second numbered item, with a nested list:
- A nested bullet.
- Another nested bullet.
Third numbered item.
1. And, for good measure...
2. An ordered list.

1.3Math#

Inline math should sit on the text baseline: $x + y = z$ , the reals $\bR$ , the naturals $\bN$ , a topology $\Tau$ , a category $\sf{C}$ , a norm $\norm{v}$ , an absolute value $\abs{w}$ , and a vector $\vb{u}$ .

Display math.

\sum_{k=1}^{n} k = \frac{n(n+1)}{2}.

An aligned block:

\begin{align*} a &= b + c \\ &= d + e + f. \end{align*}

A partial derivative $\frac{\partial f}{\partial x}$ , a second one $\frac{\partial^{2} f}{\partial x^{2}}$ , and a fraction with limits: $\lim_{n \to \infty} \frac{1}{n} = 0$ .

2Boxes#

2.1Numbered Boxes#

[2.1.1]Axiom(An Axiom With a Title)#

This is an axiom box. It should be teal.

[2.1.2]Definition(A Definition With a Title)#

This is a definition box. It should be green. Definitions are the most common box in the notes, so this one also contains inline math $x \in \bR$ to check spacing inside a box.

[2.1.3]Theorem(A Theorem With a Title)#

This is a theorem box. It should be red.

[2.1.4]Proposition(A Proposition With a Title)#

This is a proposition box. It should be yellow.

[2.1.5]Lemma(A Lemma With a Title)#

This is a lemma box. It should be purple.

[2.1.6]Corollary(A Corollary With a Title)#

This is a corollary box. It should be blue.

2.2Numbered Boxes, Part Two#

[2.2.1]Remark(A Remark With a Title)#

This is a remark box.

[2.2.2]Example(An Example With a Title)#

This is an example box.

[2.2.3]Recap(A Recap With a Title)#

This is a recap box. It should be slate grey.

[2.2.4]Problem(A Problem With a Title)#

This is a problem box. It should be a stronger blue than the corollary.

A box with no title argument at all:

[2.2.5]Definition#

This definition was declared without an optional title, so the header should show only its number and the word DEFINITION.

2.3Inner Boxes#

Inner boxes carry no number of their own and inherit the colour of whatever box encloses them.

[2.3.1]Theorem(Enclosing Theorem)#

A theorem containing a proof, so the proof rule should be red.

Proof.

This is a proof box. It should end with a QED mark on the right.

[2.3.2]Definition(Enclosing Definition)#

A definition containing an intuition block, so its rule should be green.

Intuition.

This is an intuition box. Unlike a proof, it carries no QED mark.

[2.3.3]Problem(Enclosing Problem)#

A problem containing a solution.

Solution.

This is a solution box.

A proof outside any box, which should fall back to the default grey rule.

Proof.

A standalone proof with nothing enclosing it.

3Diagrams#

3.1A Commutative Diagram#

A single tikzcd diagram.

3.2Two Diagrams and a Caption#

Two diagrams, how bold!

3.3A Picture With Colour#

A picture with COLORS! This must also survive light to dark mode switching.

4Structure and Edge Cases#

4.1Subsubsections#

The section above this one is level two. What follows is level three.

4.1.1A Level Three Heading#

More.

4.1.2A Second Level Three Heading#

More!

4.2Long Prose#

This paragraph exists purely to occupy vertical space.

4.3The End#

[4.3.1]Remark#

This is the final box in the document, and exists so that the last entry in the contents sidebar has content beneath it.
