HTMLDokuments

HTMLDokuments are documents written in Hypertext Markup Language that define the structure and presentation of web content. They are plain text files that browsers interpret to render pages.

The standard structure begins with a doctype declaration and an html element containing a head and a body. The head holds metadata such as the title, character encoding, links to stylesheets, and scripts; the body contains visible content.

Content within HTMLDokuments is organized with elements such as h1–h6, p, ul, li, a, img, video, and form controls. Semantics and accessibility are improved by using structural elements like header, nav, main, section, article, aside, and footer.

HTML5 is the current core standard; it emphasizes semantic markup, a robust media model, and a forgiving syntax that browsers can parse even with minor errors. The living standard is maintained by WHATWG and, for formal reference, W3C.

HTMLDokuments are typically saved with .html or .htm extensions and served over HTTP(S). The recommended character encoding is UTF-8, declared in the head with meta charset="UTF-8".

Validation and compatibility: authors often validate with online validators to catch syntax or accessibility issues. Modern browsers render most well-formed HTMLDokuments consistently, but differences can occur with older features or vendor-specific behaviors.

Security and performance: keep scripts external and defer loading; optimize images; use semantic markup. Accessibility is integral for inclusive web design.
