W3C

Web Design and Applications

Web Design and Applications involve the standards for building and Rendering Web pages, including HTML, CSS, SVG, device APIs, and other technologies for Web Applications (“WebApps”). This section also includes information on how to make pages accessible to people with disabilities (WCAG), to internationalize them, and make them work on mobile devices.

HTML & CSS Header link

HTML and CSS are the fundamental technologies for building Web pages: HTML (html and xhtml) for structure, CSS for style and layout, including WebFonts. Find resources for good Web page design as well as helpful tools.

JavaScript Web APIs Header link

Standard APIs for client-side Web Application development include those for Geolocation, XMLHttpRequest, and mobile widgets. W3C standards for document models (the “DOM”) and technologies such as XBL allow content providers to create interactive documents through scripting.

Graphics Header link

W3C is the home of the widely deployed PNG raster format, SVG vector format, and the Canvas API. WebCGM is a more specialized format used, for example, in the fields of automotive engineering, aeronautics.

Audio and Video Header link

Some of the W3C formats that enable authoring audio and video presentations include HTML, SVG, and SMIL (for synchronization). W3C is also working on a timed text format for captioning and other applications.

Accessibility Header link

W3C’s Web Accessibility Initiative (WAI) has published Web Content Accessibility Guidelines (WCAG) to help authors create content that is accessible to people with disabilities. WAI-ARIA gives authors more tools to create accessible Web Applications by providing additional semantics about widgets and behaviors.

Internationalization Header link

W3C has a mission to design technology that works across cultures and languages. W3C standards such as HTML and XML are built on Unicode, for instance. In addition, W3C has published guidance for authors related to language tags bi-directional (bidi) text, and more.

Mobile Web Header link

W3C promotes “One Web” that is available on any device. W3C’s Mobile Web Best Practices help authors understand how to create content that provides a reasonable experience on a wide variety of devices, contexts, and locations.

Privacy Header link

The Web is a powerful tool for communications and transactions of all sorts. It is important to consider privacy and security implications of the Web as part of technology design. Learn more about tracking and Web App security.

Math on the Web Header link

Mathematics and formula are used on the Web for business reports, education materials and scientific research. W3C’s MathML enables mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this functionality for other types of content.

Last week the World Wide Web Consortium (W3C) published “ Internationalization Tag Set (ITS) 2.0” as a W3C Recommendation. So, what is ITS 2.0, who is behind it, and why should you care?

Like the Tunnels of Disneyland

Let’s compare this with Disneyland: you may not care about how the magic comes to life, as long as you are entertained. In the same way you don’t care how Web content in your language was created, as long as it conveys the information you need.

But there are many behind-the-scences tunnels in Disneyland, with thousands of people and a lot of machinery interacting to make your experience perfect. The same is true for multilingual Web content creation: it’s a complex process, often involving many people, tasks and tools: content creation in one language, preparation for localization, and actual translation into potentially dozens of languages, quality assurance, and much more.

Like in the tunnels beneath Disneyland, you can be sure that communication in such complex workflows is key to making things work correctly, in a timely and cost-effective manner. ITS 2.0 provides standard meta-data to support that communication, with a focus on automation: ITS 2.0 helps integrate content management systems, machine translation engines and computer assisted translation tools as well as human players. It enables them to work together seamlessly to reduce the overheads associated with building your Disneyland in your language.

A key Technology developed by key Drivers of the Multilingual Web

The European Commission supported the development of ITS 2.0 , to foster the vision of a European single digital market. ITS 2.0 was created by the Multilingual Web – Language Technology Working Group in just 18 months – a fast outcome in the standardization realm. This was only possible because we had the right people at the table. To give three of many examples: Pedro Luis Díez Orzas, CEO of Spanish language service provider Linguaserve, assured that ITS 2.0 was road-tested with major clients such as the Spanish Tax Office already during its development. This provided valuable input from the end users on the design of ITS 2.0. And the group co-chairs Dave Lewis and David Filip from the Centre for Next Generation Localization assured that ITS 2.0 feeds into core localization and language technology research goals and is harmonised with other standardization efforts in the realm of Web technologies as well as localisation and language technology.

Diving into the tunnels

If you want to learn more, consider as a start to use the HTML5 Translate attribute when creating Web content in your language. It is understood by both online machine translation systems and many ITS 2.0 tools . Then dive deeper into the tunnels and look into usage scenarios for ITS 2.0. Finally and now a bit unlike Disneyland, you yourself will be able to make the magic of the multilingual Web happen.

Web developers are key in the evolution of the Web, shaping its future. Their works impact on the quality of the Web –its contents, user experience and accessibility. Having this in mind, in the process of leading the Web to its full potential, W3C offers professional training activities with the main objective of “educating” developers about using W3C technologies. For over five years, W3C has organized official courses on Web standards, training developers on best practices in order to preserve and enhance the quality of Web sites and applications.

Hundreds of professionals have been taught by the best international experts on Mobile Web, HTML5, and JavaScript. Now, we are pleased to announce a new course on HTML5 (Web Design Fundamentals) for Spanish-speaking students. The content of this course is the same as the original English version, but adapted to the Spanish-speaking community. This 6-week-long course will start on 18 November 2013. Period for “early bird” registration ends on 8 November 2013, so register now to get the discount.

Read the full description of the HTML5 course in Spanish for information about fees, outline and more. Also, see all the courses in W3DevCampus.

The MultilingualWeb-LT Working Group has published a W3C Recommendation of Internationalization Tag Set (ITS) Version 2.0.

ITS 2.0 provides a foundation for integrating automated processing of human language into core Web technologies. ITS 2.0 bears many commonalities with its predecessor, ITS 1.0, but provides additional concepts that are designed to foster the automated creation and processing of multilingual Web content.

Work on application scenarios for ITS 2.0 and gathering of usage and implementation experience will now take place in the ITS Interest Group.
