A dynamic web page is a web page that includes content that is updated regularly or changes depending on various factors, such as the user's input, location, time zone, or preferences¹. Dynamic web pages are often used for websites that need to provide personalized, interactive, or frequently updated information, such as news sites, blogs, e-commerce sites, social media platforms, or web applications².

Dynamic web pages work by using a server-side scripting language, such as PHP, Python, or ASP.NET, to connect with a database and generate the HTML content based on the user's request³. The server-side script runs on the web server and sends the HTML code to the user's browser. The browser then renders the HTML code and displays the web page to the user.

Dynamic web pages can also use client-side scripting languages, such as JavaScript, to manipulate the HTML elements and create dynamic effects on the web page. Client-side scripts run on the user's browser and can interact with the user's actions or events. For example, client-side scripts can validate user input, change the style or content of an element, or make asynchronous requests to the server using AJAX².

Dynamic web pages offer several advantages over static web pages, which are web pages that have fixed content and layout and do not change unless they are manually edited by the web developer. Some of the advantages of dynamic web pages are:

• They can provide more functional and interactive websites that respond to user needs and preferences².

• They can make it easier to update and maintain the website content without having to edit each individual HTML file³.

• They can help in improving the search engine ranking and traffic of the website by providing fresh and relevant content².

• They can reduce the load on the web server by offloading some of the processing to the user's browser¹.

However, dynamic web pages also have some drawbacks, such as:

• They can be more complex and costly to develop and host than static web pages³.

• They can be more vulnerable to security risks and errors than static web pages².

• They can be slower to load than static web pages if the server-side script or database query takes a long time to execute³.
