HTML – HEADER
The <header> element in HTML represents the introductory content of a webpage or a specific section. It typically contains elements such as headings (<h1> to <h6>), logos, introductory paragraphs, or navigation menus. <header> can be used at both the document level and within individual sections (<section>, <article>). It provides a clear, semantic way to introduce content, making it easier for search engines and assistive technologies to understand the document structure. Unlike <head>, which contains metadata, <header> holds visible content. A single page can have multiple <header> elements, each associated with different sections. For example, a blog post may have a main page header and individual headers for each post. Additionally, using <header> improves SEO by organizing content in a logical hierarchy and enhancing accessibility. However, it should not be nested inside elements like <footer> or another <header>. Proper use of <header> ensures a well-structured, accessible webpage.
The <title> tag sets the webpage’s title, shown on browser tabs and search results. <meta> defines metadata like character encoding, viewport settings, and SEO descriptions. <link> connects external resources, commonly stylesheets or icons. <base> specifies the base URL for relative links. <style> includes internal CSS for inline styling. <script> embeds JavaScript for dynamic functionality, while defer and async control script loading. <noscript> provides fallback content for users with disabled or unsupported JavaScript. These tags, when used in the <head> section, enhance SEO, user experience, and browser compatibility by defining the document’s structure, style, and behavior.
