[S1] ## 🧠 핡심 κ°œλ… (Core concepts) - This folder (`Topic_HOWTO`) wikifies the W3Schools HOW TO cookbook, one knowledge page per recipe, in P-Reinforce v3.1 format β€” same convention as every other `Topic_*` folder in this series. [S1] - **Scope decision** (user-confirmed 2026-07-04): full P-Reinforce docs for ALL ~326 recipe pages, at the same depth as language-tutorial chapters, despite recipes being far more repetitive/lower-insight-density than concept lessons. [S1] - **Excluded**: `howto_blog_*` (3 pages β€” career-advice blog posts, not code recipes: become_frontenddev, developer_job, hire_developers). Everything else from the sidebar is included (CSS/JS/HTML recipes, Google integrations, "website guide" pages, and utility/logic snippets). [S1] - **File prefix**: `HOWTO_` for all files, folder `Topic_HOWTO`. Source slugs use `howto_` prefix, `.asp` extension (verified). [S1] - **Progress:** **46 of 326 planned docs complete** (CSS Layout & Positioning, CSS Buttons sections done). Next: CSS Navigation & Menus section. - Every page roots its Knowledge Graph back to this `[[W3Schools HOW TO]]` node. ## πŸ“– μ„ΈλΆ€ λ‚΄μš© (Details) ### CSS Layout & Positioning (26) - [[HOWTO CSS About Page]] βœ… -
