网页进程设计是指使用网页设计进程语言设计交互式的网页，又称动态网页，动态网页是指网页的内容是否可根据某种条件的改变而自动改变，如网页计数器就是动态的，当有人点击我们的网页时，网页计数器的值会自动增加；BBS论坛也是动态的，当用户在论坛上发布信息时，网页内容会自动更新，显示出新发布的信息及相关回复；等等。需要注意的是GIF动画和Flash动画是静态的。因为，这些动画一旦制作完成后，就不会再改变了，尽管Flash动画可以响应用户的事件。

Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web engineering, web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. Most recently Web development has come to mean the creation of content management systems or CMS. These CMS can be made from scratch, proprietary or open source. In broad terms the CMS acts as middleware between the database and the user through the browser. A principle benefit of a CMS is that it allows non-technical people to make changes to their web site without having technical knowledge.
