Using Lynx API Docs

Overview

Pre-training knowledge is insufficient for Lynx. Lynx is a rendering platform (like a browser) with its own elements, non-standard CSS behavior, unique layout systems, and web-incompatible defaults. Always retrieve from the installed API docs before writing or modifying Lynx page code.

Core Rule

MUST ALWAYS read the relevant API docs BEFORE writing or editing any Lynx code.

Do not rely on web CSS knowledge. Do not assume standard HTML behavior. Do not guess element APIs. Lynx is a distinct platform with its own rules.

Why Web Knowledge Fails

Lynx is not a web browser. Web assumptions produce broken Lynx code:

• Elements: <view>, <text>, <image> — not <div>, <span>, <img>
• CSS defaults: border-box, no margin collapsing, Linear layout (not Flow)
• Properties: Many CSS properties are unsupported or behave differently — always check css/ docs

Every web assumption is a potential bug.

How to Use the Docs

1. Identify what you're working on (layout, CSS, element, migration, pattern)
2. Look up the relevant doc file from the table below
3. Read the doc BEFORE writing or editing code
4. Apply the rules and constraints from the doc
5. If uncertain, search the elements/ or css/ directories

Quick Reference

Core Rules

The compact layout decision rules and key CSS constraints are documented in quick-reference.md. Most critical:

• Text must use <text> component
• Default box-sizing is border-box (not content-box)
• No margin collapsing
• Use rem + vw for screen adaptation

Red Flags — Stop and Read Docs

• Adding a <div> or <span> → Lynx uses <view>, <text>
• Using margin without checking if margin collapsing applies → It doesn't
• Assuming content-box → Default is border-box
• Using web CSS properties without checking css/supported-properties.md
• Guessing element attributes → Read elements/<name>.md
• Choosing rpx for web-portable code → rpx is Lynx-specific; use rem + vw for web compatibility
• Writing plain text without <text> wrapper → Invalid in Lynx
• Using web pseudo-classes without checking css/pseudo-classes.md
• Assuming standard HTML flow layout → Lynx uses linear layout by default
