Basic Types and Requirements for Web Designing: Given by Pseudo Technology

Web site design crosses multiple disciplines of information systems, information technology and communication design. The web site is an information system whose components are sometimes classified as front-end and back-end. The observable content (e.g. page layout, user interface, graphics, text and audio) is known as the front-end. The back-end comprises the organization and efficiency of the source code, invisible scripted functions, and the server-side components that process the output from the front-end. Depending on the size of a Web development project, it may be carried out by a multi-skilled individual (sometimes called a web master), or a project manager may oversee collaborative design between group members with specialized skills.

Multidisciplinary requirements:

Issues: As in collaborative designs, there are conflicts between differing goals and methods of web site designs. These are a few of the ongoing ones.

1. Lack of collaboration in designIn the early stages of the web, there wasn’t as much collaboration between web designing and larger advertising campaigns, customer transactions, social networking, intranets and extranets as there is now. Web pages were mainly static online brochures disconnected from the larger projects. Many web pages are still disconnected from larger projects. Special design considerations are necessary for use within these larger projects. These design considerations are often overlooked, especially in cases where there is a lack of leadership, lack of understanding of why and technical knowledge of how to integrate, or lack of concern for the larger project in order to facilitate collaboration. This often results in unhealthy competition or compromise between departments, and less than optimal use of web pages.

2. Liquid versus fixed layoutsOn the web the designer has no control over several factors, including the size of the browser window, the web browser used, the input devices used (mouse, touch screen, voice command, text, cell phone number pad, etc.) and the size and characteristics of available fonts. Some designers choose to control the appearance of the elements on the screen by using specific width designations. This control may be achieved through the use of a HTML table-based design or a more semantic div-based design through the use of CSS. Whenever the text, images, and layout of a design do not change as the browser changes, this is referred to as a fixed width design. Proponents of fixed width design prefer precise control over the layout of a site and the precision placement of objects on the page. Other designers choose a liquid design. A liquid design is one where the web designing moves to flow content into the whole screen, or a portion of the screen, no matter what the size of the browser window. Proponents of liquid design prefe greater compatibility and using the screen space available. Liquid design can be achieved through the use of CSS, by avoiding styling the page altogether, or by using HTML tables (or more semantic divs) set to a percentage of the page. Both liquid and fixed design developers must make decisions about how the design should degrade on higher and lower screen resolutions. Sometimes the pragmatic choice is made to flow the web designing between a minimum and a maximum width. This allows the designer to avoid coding for the browser choices making up The Long Tail, while still using all available screen space. Depending on the purpose of the content, a web designer may decide to use either fixed or liquid layouts on a case-by-case basis. Similar to liquid layout is the optional fit to window feature with Adobe Flash content. This is a fixed layout that optimally scales the content of the page without changing the arrangement or text wrapping when the browser is resized.

3. Flash.Adobe Flash (formerly Macromedia Flash) is a proprietary, robust graphics animation or application development program used to create and deliver dynamic content, media (such as sound and video), and interactive applications over the web via the browser. Adobe Flash is today widely used in Web Designing. Flash is not a standard produced by a vendor-neutral standards organization like most of the core protocols and formats on the Internet. Flash is much more restrictive than the open HTML format, though, requiring a proprietary plug-in to be seen, and it does not integrate with most web browser UI features like the “Back” button.According to a study, [1] 98% of US Web users have the Flash Player installed. [2] Numbers vary depending on the detection scheme and research demographics. [3] Many graphic artists use Flash because it gives them exact control over every part of the design, and anything can be animated and generally “jazzed up”. Some application designers enjoy Flash because it lets them create applications that do not have to be refreshed or go to a new web page every time an action occurs.
