Semantic Markup
Semantic markup is a web development practice that uses HTML elements to convey the meaning and structure of content, rather than just its appearance. It involves selecting tags that describe the purpose of the content, such as <header>, <article>, or <nav>, to improve accessibility, SEO, and code maintainability. This approach helps browsers, search engines, and assistive technologies better understand and interpret web pages.
Developers should use semantic markup to create more accessible and SEO-friendly websites, as it enhances screen reader compatibility and search engine indexing. It is essential for modern web development, particularly in projects requiring compliance with accessibility standards like WCAG or when building content-heavy sites like blogs and news portals. Semantic HTML also simplifies styling with CSS and improves code readability for team collaboration.
