HTML is fundamentally designed to be error-tolerant and forgiving for non-professionals, unlike JavaScript which fails on simple mistakes.
Tim Berners-Lee created the World Wide Web at CERN to facilitate information sharing among scientists, with resilience built in from the start.
Browsers ensure compatibility by ignoring unrecognized HTML tags and treating them as generic elements in the DOM, as seen with the noscript tag.
Deprecated tags like blink and marquee can be brought back to life using CSS animations, demonstrating HTML's flexibility.
The browser's tokenizer processes HTML character by character, allowing for unconventional but valid tag names which enables frameworks like Angular and Vue.
Despite HTML's flexibility with custom tags, using proper semantic elements like the button tag is essential for accessibility and built-in browser functionality.
The tree builder ensures a valid DOM by automatically inserting missing elements like html and body, and by intelligently fixing improperly nested tags.
The web was designed for everyone to create and share content, so developers should build personal websites instead of relying solely on commercial platforms.
The noscript tag's content is treated as plain text by the parser, which explains why it cannot be nested, styled, or contain a functional script tag.
