Highlight Styles

Highlights draw attention to specific regions of the terminal during playback. Each style creates a different visual effect. All examples below target a cell region and auto-play with loop.

Style: Outline

A simple 2px border around the target region. Highlighted text: Found 4 modules

Style: Underline

A solid line beneath the target — useful for drawing attention to specific text without obscuring it. Highlighted text: src/core.py:42 — unused import

Style: Underline (Wavy)

A wavy underline, similar to spell-check or error indicators in code editors. Great for highlighting errors. Highlighted text: TypeError: unsupported operand type(s)

Style: Background

A subtle translucent background fill behind the target region. Highlighted text: version = "2.1.0"

Style: Spotlight

Background fill with an outer glow, making the target “pop” against the surrounding content. Highlighted text: ✨ Build complete! Output: _site/

Style: Glow

An animated neon-style glow around the target. This example also uses pulse: true for a breathing effect. Highlighted text: v0.9.0

Style: Box

Combines a border with a translucent fill — the classic “selection rectangle” look. Highlighted text: ✓ 48 passed and ✓ Coverage: 94%

Style: Badge (Before)

Border with a labeled badge above the target region. Use badge_text to set the label. Highlighted text: ✨ Live at https://docs.example.com

Style: Badge (After)

Border with a labeled badge below the target region. Highlighted text: ~ init_project() — signature changed

Style: Bracket

A left-edge bracket marking a multi-line block of output. Great for grouping related lines. Highlighted text: the four build summary statistics lines
