about

nx_layout_default_display.nx -- map an HTML element tag name to its CSS default display kind (BLOCK / INLINE / INLINE_BLOCK). Phase 3 third primitive of NISHI_BROWSER_ROADMAP. Per W3C HTML spec § 15 (default rendering / user-agent stylesheet) and CSS Display Module Level 3, every HTML element has a default `display` value the user-agent stylesheet sets. This primitive returns that value for the subset of tags andelinwest.com + the IDE require. The eventual nx_layout_from_dom primitive (queued) walks a parsed DOM tree and calls this to assign LayoutBox.kind. Author-supplied CSS can override via the cascade (Phase 2's nx_css_apply, then a Phase 3b `display` property resolver). Subset (most common HTML5 elements): BLOCK: html body div p h1 h2 h3 h4 h5 h6 header footer main section article nav aside ul ol li dl dt dd table thead tbody tfoot tr blockquote pre figure figcaption form fieldset hr address INLINE_BLOCK: img button input textarea select INLINE: span a em strong b i u code small mark sub sup label (and any tag not in the above two lists) TEXT: handled separately by caller from text-node detection What it does NOT handle yet (Phase 3b improvements): - SVG / MathML namespace switches - <table> internal display values (table / table-row / table-cell) - <script> / <style> / <head> / <title> default-hidden treatment (these have `display: none` semantically; caller filters) - HTML5 custom elements (no default; caller's UA stylesheet) - Case-insensitive tag matching for HTML quirks mode (HTML5 parser lowercases tags; until nx_html_tokenizer normalizes, callers pre-lowercase if needed) Per cardinal feedback-honest-perf-verdict-no-aspirational-claims: every tag IS exhaustively listed in this header. genealogy_id: w3c_html5_user_agent_stylesheet_default_rendering + w3c_css_display_module_level_3
