What is a defining feature of Dynamic HTML (DHTML)?

Dynamic HTML (DHTML) is characterized by its capability to create dynamic and interactive web content by utilizing a combination of HTML, CSS, and JavaScript. This technology primarily focuses on client-side manipulation, meaning it executes within the user's web browser without the need for constant communication with the server.

The nature of DHTML allows for changes to be made in the document object model (DOM) without needing to reload the entire page, thereby enhancing user engagement and experience. While it mainly operates on the client side, it can be influenced by data from server-side scripts, which means that it has a relationship with both front-end and back-end development. This dual aspect enables developers to create rich, interactive web applications that can also interact with server-side processes when necessary.

Thus, understanding that DHTML is not confined to just front-end or back-end solutions is crucial. It's about the integration and interaction between both sides, making it a defining feature of this technology.
