Web designer

Web design is the skill of designing hypertext presentations of content that is delivered to an end-user through the World Wide Web, by way of a Web browser or other Web-enabled software like Internet television clients, microblogging clients and RSS readers. Web pages and Web sites can be static pages, or can be programmed to be dynamic pages that automatically adapt content or visual appearance depending on a variety of factors, such as input from the end-user, input from the Webmaster or changes in the computing environment (such as the site's associated database having been modified).

With growing specialization within communication design and information technology fields, there is a strong tendency to draw a clear line between web design specifically for web pages and web development for the overall logistics of all web-based services. A web site is a collection of information about a particular topic or subject. Designing a web site is defined as the arrangement and creation of web pages that in turn make up a web site. A web page consists of information for which the web site is developed. A web site might be compared to a book, where each page of the book is a web page.

There are many aspects (design concerns) in this process, and due to the rapid development of the Internet, new aspects may emerge. For non-commercial web sites, the goals may vary depending on the desired exposure and response. Some designers choose to control the appearance of the elements on the screen by using specific width designations. This control may be achieved in HTML through the use of (now disparaged) table-based design or more modern (and standard) div-based design, usually enhanced (and made more flexible) with CSS. When the text, images, and layout do not vary among browsers, this is referred to as fixed-width design. Advocates of fixed-width design argue for the designers' precise control over the layout of a site and the placement of objects within pages.

Other designers choose a more liquid approach, one which arranges content flexibly on users' screens, responding to the size of their browsers' windows. For better or worse, they concede to users more control over the rendition of their work. Proponents of liquid design prefer greater compatibility with users' various choices of presentation and more efficient use of the screen space available. Liquid design can be achieved by setting the width of text blocks and page modules to a percentage of the page, or by avoiding specifying the width for these elements altogether, allowing them to expand or contract naturally in accordance with the width of the browser.

It is more in keeping with the original concept of HTML, that it should specify, not the appearance of text, but its contextual function, leaving the rendition to be decided by users' various display devices. Web page designers (of both types) must consider how their pages will appear on various screen resolutions. Sometimes the most pragmatic choice is to allow text width to vary between minimum and maximum values. This allows designers to avoid considering rare users' equipment while still taking good advantage of available screen space.
