A static website differs from a dynamic website primarily in how content is delivered. Static websites serve fixed content where each page is coded in HTML and displays the same information to every visitor. In contrast, dynamic websites can generate content in real-time based on user interactions or inputs, often utilizing server-side scripting technologies like PHP or ASP.NET. This allows for personalized experiences and frequent content updates without needing manual intervention. Additionally, dynamic sites often engage users through forms, comments, and interactive elements, enhancing user engagement.
