# HTML And CSS Coding Standard

Public pages should be readable, crawlable, accessible, and consistent with the site they live on.

## HTML

- Use semantic landmarks and headings in order.
- Keep links clean, source-owned, and testable.
- Avoid query-string launch URLs unless a project explicitly allows them.
- Keep machine-readable metadata aligned with the public page claim.

## CSS

- Follow the site's existing design language before adding new styling.
- Keep layout responsive with stable dimensions for repeated items and controls.
- Avoid one-note palettes and decorative effects that reduce readability.
- Make text fit its container on mobile and desktop.

## Verification

- Run link and smoke checks after route or navigation changes.
- Use screenshots or browser checks for layout-heavy changes.
- Confirm sitemap or discovery output when a public page becomes part of the launch surface.

Why This File Exists

This is a LLM Wiki memory file from aiwikis.org. It is shown here because AIWikis.org is demonstrating the real source files that make the UAIX / LLM Wiki memory system work, not only summarizing those systems after the fact.

Role

This file belongs to the source-side wiki layer. It preserves a focused concept, source proxy, graph record, or operating rule so the public site can cite reviewed conclusions without flattening every reason into a single long page.

Structure

The file is structured around these visible headings: HTML And CSS Coding Standard; HTML; CSS; Verification. Those headings are retrieval anchors: a crawler or LLM can decide whether the file is relevant before reading every line.

Prompt-Size And Retrieval Benefit

Keeping this material in a separate file reduces prompt pressure because an agent can load this exact unit only when its role, source site, category, or hash is relevant. The surrounding index pages point to it, while this page preserves the full content for audit and exact recall.

How To Use It

Humans should read the metadata first, then inspect the raw content when they need exact wording or provenance.
LLMs and agents should use the source site, category, hash, headings, and related files to decide whether this file belongs in the active prompt.
Crawlers should treat the AIWikis page as transparent evidence and follow the source URL/source reference for authority boundaries.
Future maintainers should regenerate this page whenever the source hash changes, then review the explanation if the role or structure changed.

Update Requirements

When this source file changes, update the raw source layer, normalized source layer, hash history, this rendered page, generated explanation, source-file inventory, changed-files report, and any source-section index that links to it.
