The design of the Web site crosses multiple disciplines of the information systems, of the technology of the information and the design of the communication. The Web site is an information system whose components are classified sometimes like advance and final. The observable content (e.g disposition of page, using interface, graphs, audio text and) is known like the advance one. The part includes the organization and the effectiveness of the source code, the invisible functions with script, and of the components of the servant-side that process the exit of the advance one. Following the size of a project of development of the Web, he can be realized by an individual of multiple talents (sometimes called a master of the fabric), or a project manager can supervise design of collaboration between the members of the group with specialized abilities. Multidisciplinary requirements: Editions: Like in collaboration designs, there are conflicts between the goals and the methods of differentiation of designs of the Web site. These are some of ones.1 in course. Deficiency of the collaboration in designIn the first times of the fabric, there wasn’ t as much greater collaboration between the design of the fabric and advertizing campaigns, the transactions of the client, establishment of a social network, intranets and extranets as there now it is. The Web pages was mainly static pamphlets in line disconnected of the greatest projects. Many Web pages still becomes disconnected of greater projects. The special considerations of the design are necessary for the use within these greater projects. These considerations of the design are often ignored, especially in case there is a deficiency of the direction, deficiency of the understanding of because and technical knowledge of how integrating, or deficiency of the preoccupation by the greatest project to facilitate the collaboration. This often gives rise to the competition or the unhealthy commitment between the departments, and the use than less optimal of the fabric pages.2. The fixed liquid against layoutsOn the fabric the designer does not have ninguÌ  n control on several factors, including the size of the window of hojeador, the used web browser, the input devices used (mouse, touch screen, commando of the voice, text, cushion of the number of the cellular telephone, etc.) and the size and the characteristics of sources available. Some designers choose to control the aspect of the elements in the screen being used specific designations of the width. This control can be reached with the use of a table-based design HTML or a design div-based more semantic with the use of the CSS. Whenever the text, the images, and the disposition of a design does not change whereas the hojeador changes, this talks about as fixed design of the width. The authors of the fixed design of the width prefer exact control over the disposition of a site and the positioning of the precision of objects in the page. Other designers choose a liquid design. A liquid design is one where the fabric design moves to the content of the flow to the whole screen, or a portion of the screen, does not concern what the size of the hojeador window. Authors of the greater compatibility and to use of prefe liquid of the design the space of the screen available. The liquid design can be reached altogether with the use of the CSS, avoiding working the page, or using the tables of the HTML (or divs more semantic) they fix to a percentage of the page. The liquid and fixed revealers of the design must make decisions exceeds how the design must degrade in higher and lower resolutions of the screen. The pragmatic decision is taken sometimes to flow the fabric that it designs between a minimum and maximum width. This allows that the designer avoids the codification for the options of the hojeador that compose the long tail, whereas still using all the space available of the screen. Following the intention of the content, a designer of the fabric can decide to use the determined or liquid dispositions case by case. Similar to the liquid disposition is the optional adjustment to the characteristic of the window with the content of sparkle of Adobe. This one is a fixed disposition that scales optimal the content of the page without the change of the adjustment or of the text that surrounds when the hojeador is resized.3. Flash.Adobe flashes (before Macromedia flash) are a robust animation or a program of the development of applications used to create and to give to the dynamic content, average proprietor, graphs (such as interactive sound and video), and uses on the fabric via the hojeador. The flash of Adobe today is widely used in the design of the Web. The flash is not a standard produced by a salesman-neutral organization of standards as most of the protocols and the formats of the base in the Internet. The flash is much more restrictive that the abierto format of the HTML, although, to require a propietary plug to be seen, and the nonIntegra with the majority of the characteristics of web browser UI like the “Back” button. According to a study, [1] 98% of users of Web of the USA has the player of installed sparkle. [2] the numbers varies following the demographic data of the scheme and the investigation of the detection. [3] Many graphical artists uses the flash because it gives exact control them on each part of the design, and any thing can generally be animated and” up&quot jazzed;. Some designers of use enjoy the flash he lets because them create the uses that they do not have to be recovered or to go to a new Web page happens an action every time.
