Web Development
Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). This can include web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. However, among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services.
For larger organizations and businesses, web development teams can consist of hundreds of people (web developers). Smaller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department.
Web Design
Web design is the process of designing websites - a collection of online content including documents and applications that reside on a web server/servers.[citation needed]
As a whole, the process of web design includes planning, post-production, research, advertising, as well as media control that is applied to the pages within the site by the designer or group of designers with a specific purpose. The site itself can be divided into its main page, also known as the home page, which cites the main objective as well as highlights of the site's daily updates; which also contains hyperlinks that functions to direct viewers to a designated page within the site's domain.
Cross-browser refers to the ability for a website, web application, HTML construct or client-side script to support all the web browsers. The term cross-browser is often confused with multi-browser. Multi-browser is a new paradigm in web development that allows a website or web application to provide more functionality over several web browsers, while ensuring that the website or web application is accessible to the largest possible audience without any loss in performance. Cross-browser capability allows a website or web application to be properly rendered by all browsers. The term cross-browser has existed since the web development began.
The term is still in use, but to lesser extent. The main reasons for this are: Later versions of both Internet Explorer and Netscape included support for HTML 4.0 and CSS1, proprietary extensions were no longer required to accomplish many commonly desired designs. Somewhat more compatible DOM manipulation techniques became the preferred method for writing client-side scripts. The browser market has broadened, and to claim cross-browser compatibility, the website is nowadays expected to support browsers such as Mozilla Firefox, Opera, Google Chrome and Safari in addition to Internet Explorer and Netscape. There has been an attitude shift towards more compatibility in general. Thus, some degree of cross-browser support is expected and only its absence needs to be noted.
