Check the HTML contracts before adapting a sample into an application.
Review the lessons
- HTML Elements Reference: select elements by content contract
- HTML document skeleton: declare language, encoding, and a real title
- HTML title and metadata: distinguish document identity from page copy
- HTML headings and paragraphs: expose a readable outline without styling tricks
- HTML lists: choose ordered, unordered, or term-description structure
- HTML anchors: use href for navigation and stable fragment targets
Common Mistakes
Markup examples do not supply missing routes, assets, persistence, or authorization checks.
