HTML code FYI is a private educational project by Mario V.W.B.R. Obst, developed in collaboration with artificial intelligence. AI assists with structure, writing, examples and programming. Mario supplies the project’s direction and personal experience.
No promise of complete accuracy
AI-generated material can sound convincing and still be wrong. Human-written material can contain mistakes too. This site does not guarantee complete accuracy, completeness, suitability or continuing currency. General explanations are not individual legal, privacy or security advice. Nothing in this notice excludes responsibility that cannot lawfully be excluded.
Read, test, check again
Understand an example before using it. Try it in your own context, test relevant browsers and screen sizes, and compare important details with current primary documentation. A successful demonstration does not prove that every possible case is covered.
How articles are prepared
Explanations and teaching examples are written for this project. Further-reading links identify relevant standards or official documentation. A first technical reading of the 30 guides has been completed. Local checks cover page structure, links, metadata, JavaScript logic and representative browser behaviour. These checks do not cover every browser, assistive technology or possible input. The current articles are editorial drafts; they are not presented as independently certified or exhaustively tested.
Sources and attribution
We aim to explain ideas in our own words rather than reproduce other publications. Quotations and reused material must be identified and used under applicable permissions. Historical accounts draw on Mario’s own recollections and archived websites.
