Web design involves creating web pages and websites using technologies like HTML and CSS. It is a multidisciplinary field that draws from areas like graphic design, user experience design, and programming. Effective web design involves planning like defining the purpose of the site, identifying the target audience, organizing content, and documenting the site structure. The design process also considers layout, navigation, publishing, and techniques to drive traffic. Web pages can be static or dynamically generated depending on things like user input. Collaboration between different specialists is often needed for larger web development projects.

1. Web designWeb design is the skill of creating presentations of content (usually hypertext or hypermedia) 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.The intent of web design[1] is to create a web site—a collection of electronic documents and applications that reside on a web server/servers and present content and interactive features/interfaces to the end user in form of Web pages once requested. Such elements as text, bit-mapped images (GIFs, JPEGs) and forms can be placed on the page using HTML/XHTML/XML tags.

2. Typically web pages are classified as static or dynamic:

3. Static pages don’t change content and layout with every request unless a human (web master/programmer) manually updates the page. A simple HTML page is an example of static content.

4. Dynamic pages adapt their content and/or appearance depending on end-user’s input/interaction or changes in the computing environment (user, time, database modifications, etc.) Content can be changed on the client side (end-user's computer) by using client-side scripting languages (JavaScript, JScript, Actionscript, etc.) to alter DOM elements (DHTML). Dynamic content is often compiled on the server utilizing server-side scripting languages (Perl, PHP, ASP, JSP, ColdFusion, etc.). Both approaches are usually used in complex applications.The process of designing web pages, web sites, web applications or multimedia for the Web may utilize multiple disciplines, such as animation, authoring, communication design, corporate identity, graphic design, human-computer interaction, information architecture, interaction design, marketing, photography, search engine optimization and typography.

5. 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).

6. 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.Accessible Web design

7. Main article: Web accessibility

8. To be accessible, web pages and sites must conform to certain accessibility principles. These accessibility principles are known as the WCAG when talking about content. These can be grouped into the following main areas.

9. Use semantic markup that provides a meaningful structure to the document (i.e. web page)

10. Semantic markup also refers to semantically organizing the web page structure and publishing web services description accordingly so that they can be recognized by other web services on different web pages. Standards for semantic web are set by IEEE

11. Use a valid markup language that conforms to a published DTD or Schema

12. Provide text equivalents for any non-text components (e.g. images, multimedia)

13. Use hyperlinks that make sense when read out of context. (e.g. avoid "Click Here")

14. Don't use frames

15. Use CSS rather than HTML tables for layout

16. Author the page so that when the source code is read line-by-line by user agents (such as screen readers) it remains intelligible. (Using tables for design will often result in information that is not.)Website accessibility is also changing as it is impacted by Content Management Systems that allow changes to be made to webpages without the need of obtaining programming language knowledge.
