The document discusses different types of websites and technologies used to build them. A normal website uses HTML to provide basic information like company overview and contact details. A dynamic website or web application uses a database and allows users to create accounts, purchase items, and interact with the site. Popular software to build websites include Microsoft Visual Studio, Adobe Dreamweaver, and Microsoft Expression. HTML defines the structure and content of a webpage, while CSS controls the design and layout. The two work together to provide an attractive and functional design for websites.
