Dynamic Website

              A dynamic website is one that changes or customises itself on a regular basis and without human intervention. Computer
              code that generates HTML, generates server-side dynamic pages “on the fly” (CSS are responsible for appearance and
              thus, are static files). To create dynamic web systems and dynamic sites, a variety of software solutions are available,
              including CGI, Java Servlets and Java Server Pages (JSP), Active Server Pages, and ColdFusion Markup Language (CFML).
              To make it faster and easier to construct sophisticated dynamic websites, various web application frameworks and
              web template systems are available for general-purpose programming languages such as Perl, PHP, Python, and Ruby.
              A website can show the present state of a user conversation, monitor a changing scenario, or provide information that
              is tailored to the needs of the individual user.
              News channel websites are an example of dynamic websites, as is an ecommerce website with a large number of
              products that allows a user to enter a search request, such as for the keyword ‘shoes.’

              Features of Dynamic Website
              Some of the features of dynamic website are as follows:

              Ð ÐChoosing your website’s display format: Dynamic websites tell your web browser that which version of website is
                 to be loaded i.e., mobile or desktop version.

              Ð ÐAdjust language settings: Dynamic websites can display web content in different languages, based on where their
                 visitors are located.

              Ð ÐMake  content  or  product  recommendations:  Dynamic  websites  can  process  cookies  to  customize  content  or
                 product recommendations that are helpful to your users.

                 2.3 INTRODUCTION TO HTML

              HTML is the most widely used language for developing webpages. HTML webpages are simple text files with special
              “tags” that a web browser interprets and displays on your computer screen.

              Ð ÐHTML stands for HyperText Markup Language.
              Ð ÐAn HTML file is a text file that contains small markup tags that instruct the web browser on how to display the page.

              Ð ÐThe .htm or .html file extension is required for an HTML file.
                         Notes


                         Tim Berners-Lee initially introduced HTML tags on the Internet in late 1991, and a document named "HTML Tags"
                         was the first publicly available description of HTML. It outlines the 18 elements that make up HTML's initial,
                         rather simplistic design.



              Types of HTML Editor
              There are mainly two types of HTML editors named WYSIWYG editor and Text editor. Let us now discuss these editors.
