webpage

A webpage is a document that is part of a website and delivered by a web server to a client over the Internet using the HTTP or HTTPS protocol. It is typically written in markup languages such as HTML and may include stylesheets and scripts that control presentation and behavior. Each page is identified by a unique URL.

A webpage's content is structured with HTML elements that describe headings, paragraphs, lists, links, images, forms, and multimedia. Styling is provided by CSS, and interactivity by JavaScript. Good pages use semantic markup, accessible navigation, and responsive design to adapt to different devices and screen sizes.

Pages can be static, containing fixed content stored on the server, or dynamic, generated on request by server‑side software or client‑side JavaScript. Single‑page applications load much of their content asynchronously, while traditional sites rely on multiple distinct pages.

Web pages are hosted on web servers and identified by a URL. They may be augmented by metadata such as title tags, descriptions, keywords, and viewport settings to improve accessibility and search engine performance. Accessibility considerations include alt text for images, proper color contrast, and keyboard navigation.

Search engines index pages to support discovery, and pages often link to one another through navigation menus and hyperlinks. Standards from bodies such as the World Wide Web Consortium (W3C) govern HTML, CSS, and related technologies. Performance and security practices—caching, minification, content delivery networks, and TLS encryption—affect loading times and user trust.
