Resilience
summary
HTML tolerates broken pages: browsers use a tokenizer with 68 tokenizer states and a tree builder that auto‑inserts missing html/head/body nodes, fixes bad nesting and preserves unknown tags as generic elements so the 1990s first website still loads. Practical consequences: custom elements and Angular/Vue quirks work, emojis are allowed in tag names (if they start with a letter), a blink tag can be revived with CSS, but no-script never renders content and a script inside it is ignored.
