Basics of Web Design

Presentations delivered through the World Wide Web are usually created through web design. Thus, web design can be defined as the skill used to create these presentations. Designers create such presentations using the web browser or software such as internet television clients, RSS readers as well as microblogging clients. The software used has to be web - enabled. This is normaly carried out in order to generate an anthology of electronic files located on a server. It is also necessary for the presentation of content as well as interactive features or interfaces so that the end user can easily access them in the form of pages. Web design involves the placement of several elements including text and bit-map images such as gifs, JPEGs as well as GIFs on the page. The use of HTML, XML as well as XHTML helps designers to place these web elements.
Web design also involves the placement of other more complex media such as animations, sounds, vector graphics as well as videos. In such a case, design would therefore require the use of plug - ins which can also be fixed to the web page through HTML together with XHTML tags. Examples of plug-ins commonly used include QuickTime, Flash as well as Java run - time environment. Since there have been major developments in web design ever since its advent, most people use XHTML and XML together with Cascading Style Sheets commonly referred to as CSS. These tags are necessary in the positioning and manipulation of objects and elements on the web page. As advancements in web design keep growing, designers are slowly embracing the creation of web pages without plug - ins.
Web designers create pages that could be broadly classified under two groups; static or dynamic. The content and layout of static web pages can only be altered with manual updates created by the programmer. Dynamic pages on the other hand can be altered by an end user's input. The computing environment can also alter the content of a dynamic web page. It is however necessary to note that web design is especially concerned with the graphic design of a web page rather than the logistics as is the case in web development. Web design involves the use of several disciplines. These include search engine optimization, animation, typography, graphic design, interaction design, communication design, photography, corporate identity, marketing among others. What is more, it uses Multimedia technologies such as Flash and Silverlight together with Database technologies including PHP and ASP. Mark up together with Style sheet languages are also used, not forgetting to mention client - side scripting as well as server - side scripting.
Designers have to conform to certain principles in order to ensure that the web pages are accessible. For instance, it is advisable to use semantic markup so that the web page can have a meaningful structure. What is more, the web page should also be organized semantically so that other web services can easily recognize them on various web pages. Web designers also need to use a valid mark up language that follows the standards of a published DTD or Schema. Non text components should be presented in forms equivalent to text such as images and multimedia. Hyperlinks are also necessary but they should be placed in such a way that when one reads the text, it still makes sense. For layout in Web design apply CSS instead of HTML tables. Frames should also be avoided. It is important for any web design process to consider the intelligibility of the web pages while it should also be easily accessible to the users.
