HTMLsivu

HTMLsivu is the Finnish term for an HTML page, a document written in HTML that is delivered to a web browser and forms the basic unit of content on the World Wide Web.

A typical HTMLsivu declares a Doctype, contains an html element, a head with a title and metadata, and a body that holds the visible content. Modern HTML emphasizes semantics: using header, nav, main, section, article, aside, and footer helps structure and accessibility.

Standards are maintained by WHATWG and W3C; HTML5 is the current core standard. Valid markup improves interoperability, accessibility, and search engine optimization. Styling is typically done with CSS and behavior with JavaScript, often loaded from external files, while an HTMLsivu can include inline styles or scripts.

Linking and media: HTML provides anchors for hyperlinks, images via img, multimedia via video and audio, and forms for user input. The viewport meta tag enables responsive design so the same page renders well on different devices.

Creation and hosting: HTMLsivu files are plain text saved with .html or .htm extensions. They are served by web servers with the MIME type text/html and rendered by browsers. Pages can be static or generated server-side and enhanced on the client with scripts.

Usage: HTMLsivu remains the foundation of web content, supporting accessibility, searchability, and integration with CSS and JavaScript. As the web evolves, HTML continues to evolve through living standards that add new elements and attributes while preserving backward compatibility.
