Non Semantic Markup
Non semantic markup refers to HTML elements that do not convey meaning about the content they enclose, such as <div> and <span>. These elements are used primarily for styling and layout purposes without indicating the role or structure of the content. This approach contrasts with semantic markup, which uses elements like <header>, <article>, and <nav> to describe content meaning.
Developers should understand non semantic markup for creating flexible layouts and applying CSS styles when semantic elements are not suitable or available. It is commonly used in legacy codebases, rapid prototyping, or when precise control over presentation is needed without semantic constraints. However, overuse can harm accessibility and SEO, so it should be balanced with semantic practices.
