Answer:
dynamic
Explanation:
A dynamic web page serves out varied material to various visitors while keeping the same layout and appearance. These pages, which are often built in AJAX, ASP, or ASP.NET, require longer to render than plain static sites. They are commonly used to display data that updates regularly, such as weather forecast or market prices.
Dynamic web pages often incorporate software applications for various services and need server-side resources such as databases. A database enables the page builder to divide the design of the website from the content that will be presented to users. When they post material to the database, the website retrieves it in response to a user request.
