Homes will be known world affairs, according few keyboard or a few 10 mouse clicks can be distant friends thousands of miles away exchanges, and online munications, Inter browsing, online interactive, emerce has bee a modern part of people39。s work and lifestyle, the Inter, openness and sharing of information model, breaking the traditional mode of information dissemination many barriers for people with new opportunities. With puters and the advent of the information age, the pace of the advance of human society in gradually accelerated. In recent years the development of web design, fast people occupied. With the development of web design, a colorful online website together one scenic beauty. To design aesthetic and practical web site should be thoroughly master the building techniques. In building site, we analyzed the websites of objectives, contents, functions, structure, the application of more web design technology. 2, the definition of website How definition of websites Web site identified the tasks and objectives, the building site is the most important issue. Why people will e to your website? You have a unique service? The first people to your website is to what? They will e back? All these issues must be taken into account when the site definition of the problem. Definition site to, first of all, the entire site must have a clear understanding of what the design should understand in the end, the main purpose of the mission, how to carry out the task of anization and planning. Second, to maintain the highquality Web site. Many websites in the face of strong petition from highquality product is the greatest longterm petitive advantage. An excellent Web site should have the following: (1) users visit Web site is faster. (2) attention to the feedback and updates. To update the content of the website and timely feedback the user39。 (3) Home design to be reasonable. Home to the first impression left by visitors is important, the design must be attractive in order to have a good visual effect. The contents of the website and function The content of the web site is to be a new, fast, all three sides. The content of the website, including the type of static, dynamic, functional and things to deal with. Website content is determined in accordance with the nature of the site, in the design of the site, mercial websites, popular science site, pany websites, teaching and exchange websites, the content and style are different. We have established websites with the nature of these types of sites are not the same. The structure website (1) site structure。 (3) Visual Design。s homepage, you need to have more like CSS, javascript, CGI, and other web design technology. In building on the site of the CSS, javascript and other web design technology. CSS Application Design website (1) What is CSS? CSS is a style sheet (stylesheet) technology. Some of them called CSS (Cascading Stylesheet). (2) the bination of CSS and HTML form. Mode 1: The CSS content, as defined in the writing between the labels. Mode 2: CSS will be preserved as a separate text file, and then from labels to call. (3) CSS the web site of examples. The web site pages, and increase the following definition so that the pages show with special effects. Application Design website javascript javascript and the emergence of making information between users is not only a display and browse the relationship, but to achieve a realtime, dynamic, crossexpression. Thus based on the CGI static HTML pages will be to provide dynamic realtime information, and customer response to the operation of the Web pages replaced. javascript scripting is satisfy this demand arising from the language. It39。 Web servers can be achieved. In the process of achieving website, technology selection is very important. Former major use HTML language, the stronger the interactive website, the proposed use of ASP, JSP, PHP and other programming to help achieve, the more plex Web
