HTML vs HTMLZ

Over HTMLZ-bestandenVergelijking van sterke punten
HTML Sterke punten
- Universal — every browser, OS, email client, and document reader displays HTML.
- Plain text, human-readable, grep-able, and diffable in git.
- Flexible — pages render even with broken or partial markup (error-tolerant parser).
- Carries structure, styling (CSS), and behavior (JavaScript) in one file.
- Accessibility-friendly when written with semantic tags and ARIA attributes.
HTMLZ Sterke punten
- Simpler than EPUB.
- ZIP-of-HTML portability.
- Calibre-native.
Beperkingen
HTML Beperkingen
- Error tolerance allows sloppy markup to hide real bugs.
- Rendering depends on browser engine — pixel-perfect cross-browser output is an art form.
- Security-sensitive — unsafe HTML can execute scripts or leak data (XSS vulnerabilities).
- File size for equivalent structured data is larger than JSON or XML due to tag verbosity.
- No built-in typing or schema — contract between server and client is informal.
HTMLZ Beperkingen
- Niche — no reader support.
- Not a mainstream delivery format.
- Calibre-only.
