What is Web Designing:
Web designing is used as a general term to describe many of the various tasks involved in creating a web page. Basically, it relates to jobs focused on creating the front-end of a web page.
The web consists of hierarchy of pages, presenting information using various technologies and linked together using hyperlinks. There are two basic aspects to any web page found on the Internet. The first is a presentation that the user interacts with, usually visually, while the second is a back-end that includes information for non-human browsers.
The basic markup language used to tell a browser how to present information is called the HyperText Markup Language (HTML). A stricter version of HTML is also widely used, known as eXtensible HyperText Markup Language (XHTML). Using HTML or XHTML, a web designer is able to tell a browser how a web page should appear. In the last few years there has been a push towards separating the underlying structure of a web-page (using HTML) from the visual presentation of the site (using Cascading Style Sheets or CSS). This approach has a number of major benefits in both the short and long term, and is gathering popularity as time progresses.
