Overview

After covering mathematical expressions in Markdown, further precise formatting—similar to what is achievable in word processors or academic writing—requires additional techniques.

Font Customization

Font Families

Different font styles can be applied using specific commands:

• Roman style: \textrm{text}
• Sans serif: \textsf{text}
• Typewriter/monospaced: \texttt{text}

Example:

textrm{Roman} \quad \textsf{Sans} \quad \texttt{Mono}

Font Shapes

Various text shapes are also available:

• Upright: \textup{text}
• Italic: \textit{text}

Example:

\textup{upright} \quad \textit{italic}

Size and Color

Font color can be set using background boxes for emphasis:

\colorbox{red}{highlighted}

Other colors like yellow can also be used:

\colorbox{yellow}{notice}

Spacing Control

Units of Measurement

Common units include:

• pt: Points (standard unit)
• pc: Picas (1 pc = 12 pt)
• in: Inches (1 in = 72.27 pt)
• bp: Big points (1 in = 72 bp)
• cm/mm: Centimeters and millimeters
• em: Relative to current font size (1 em ≈ 16 px)
• px: Pixels

Space Commands

The following commands introduce various spacing levels:

A \quad A \qquad A \enskip A \thinspace A \enspace A ~ A

Explanation:

• \quad: Space equal to current font’s width
• \qquad: Double quad space
• \enskip: En-space (~1/6 of current font size)
• \thinspace: Thin space (~1/5 of current font size)
• \enspace: En-space (~1/2 of current font size)
• ~: Non-breaking space

Horizontal Adjustment

Use \hspace too adjust horizontal spacing between elements:

A \hspace{2.5cm} B

Values may be specified in pt, in, cm, px, etc., depending on layout needs.

Summary

By lveeraging these formatting options, detailed document presentation in Markdown can closely emulate professional typesetting.
