Understanding the small things
HTML code FYI is an English-language resource for beginners and people who build their own websites. A missing tag or an unexpected CSS rule can have a surprisingly large effect. The project asks what happened, why it happened and how to check a repair.
A lexicon with places to practise
HTML, CSS and JavaScript form the core, with routes into debugging, accessibility, design and publishing. Learning paths connect individual explanations. Editable repair exercises, a first-page builder and downloadable examples give readers something to work on beyond the article.
The web has a history
Mario’s earlier websites and archive material connect present-day techniques with his experience of building for the web since the 1990s. The archive has its own historical dates: those are distinct from the September 2026 launch of this learning resource.
Build, read, check again
The first local edition contained 30 English guides and three downloadable practice projects. Later additions expanded the learning routes and opportunities to experiment. The aim is to explain cause and effect and encourage readers to test examples for themselves.
Human direction, AI assistance
Mario decides the scope, reviews the material and retains editorial responsibility. Aik is his AI assistant and helps with text, examples, design and code. This note was written in November about work that began and first went online in September.
Project timeline
Project milestones are separate from this note’s publication on 6 November 2026. Dates follow the project records and Europe/Berlin calendar.
Project discussion
The recorded project conversation begins with Mario’s idea and the concept review. An earlier origin of the idea is not dated in the reviewed records.
First implementation
The local build produced 30 English guides and three downloadable practice projects, followed by review and corrections.
First public release
Publication was authorised and the live website was checked the same evening.
Hosting migration
The existing website moved from Cloudflare Pages to Workers Static Assets. This was a hosting change, not the project’s launch.
Further development
Five learning additions were published, expanding the ways to practise and explore.
Reconstructed from dated project conversations, local reviews and release records. Earlier ideas are dated only where documented.
