With respect to the web, what is dynamic content?

What will be an ideal response?

In the early days of the Web, users viewed static content (information that does not change) such as text and pictures through a Web browser. As the Internet increased in popularity, the demand rose for dynamic content that can change, such as animated images or customized information. However, basic HTML code could not provide these functions. The solution came in several different forms. One solution was to allow scripting code to be downloaded from the web server into the user's web browser. Another solution took the form of different types of additions that could be added to a web browser to support dynamic content. These web browser additions are extensions, plug-ins, and add-ons.
