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.

As the Open Web Platform expands, and apps are developed that access various sensitive resources, new ways of managing permissions to access these resources are likely to arise. The newly formed W3C Trust & Permissions Community Group will explore and evaluate such ways based upon experience with native and hybrid platforms, and drawing upon research studies. This follows on from the Paris meeting on trust and permissionsheld on 3-4 September 2014.

Resources vary in sensitivity and timeliness, e.g. when and to whom a password should be disclosed is quite different from when access to the user’s webcam should be granted. Similarly, modes of obtaining user permission vary, including asking users upfront for permission when an app is installed or first run (exemplified in Android and Windows) or asking users for permission when the application is attempting to use a given capability (exemplified in iOS) and permission can even be obtained after the fact by inviting the user to continue or to cancel an action after it has occurred, i.e. asking for forgiveness rather than permission. In some cases, the user’s actions can be taken as implicitly granting permission, such as the Windows file chooser dialog. A further approach is for users to delegate decisions on permissions to a trusted 3rd party.

The goal of this CG is to develop and articulate best practices for which modes of obtaining permission best match which resource types, and make these best practices available to both platform developers (browser and operating system vendors) and app developers. Ideally the APIs offered to apps to obtain permission to access resources should be consistent across platforms, while allowing platforms the flexibility to present a user experience that meets each platform’s needs.

The scope of this Community Group is limited to discussion and guidance on best practices, to review draft APIs from individual WG’s, and pre-standardisation work on promising ideas for better user experience obtaining permission, including trusted UI and trust delegation per Roesner et al. Work on best practices will focus on the kinds of resources that need protection, the enumeration of good ways to obtain user permission, to dis-recommend permission models that are known to be problematic, and to recommend the preferred user experience for a given kind of resource. The main focus is on the Open Web Platform, but packaged apps are not excluded.

W3C Community Groups are open to anyone to join, free of charge. If you have expertise in regard to handling trust and permissions for applications, you will be very welcome as a new member of the Trust & Permissions CG.

This is the 2-9 January 2015edition -after a hiatus on 19 December 2014- of a “weekly digest of W3C news and trends” that I prepare for the W3C Membership and public-w3c-digest mailing list (publicly archived). This digest aggregates information about W3C and W3C technology from online media —a snapshot of how W3C and its work is perceived in online media.

W3C announced today the 8th MultilingualWeb workshop in a series of eventsexploring the mechanisms and processes needed to ensure that the World Wide Web lives up to its potential around the world and across barriers of language and culture.

This workshop will be held 29 April 2015in Riga, Latvia, and is made possible by the generous support of the LIDER project . The workshop is part of the Riga Summit 2015 on the Multilingual Digital Single Market(27-29 April)

Anyone may attend all sessions at no charge and the W3C welcomes participation by both speakers and non-speaking attendees. Early registration is encouraged due to limited space.

Building on the success of seven highly regarded previous workshops, this workshop will emphasize new technology developments that lead to new opportunities for the Multilingual Web. The workshop brings together participants interested in the best practices and standards needed to help content creators, localizers, language tools developers, and others meet the challenges of the multilingual Web. It provides further opportunities for networking across communities. We are particularly interested in speakers who can demonstrate novel solutions for reaching out to a global, multilingual audience.

The W3C Internationalization Working Group has published a First Public Working Draft of Indic Layout Requirements on behalf of the Indic Layout Task Force , part of the W3C Internationalization Interest Group.

This document describes the basic requirements for Indic script layout and text support on the Web and in eBooks. These requirements provide information for Web technologies such as CSS, HTML and SVG about how to support users of Indic scripts. The current document focuses on Devanagari, but there are plans to widen the scope to encompass additional Indian scripts as time goes on.

Publication as a First Public Working Draft, signals the beginning of the process, rather than an end point. We are now looking for comments on the document. Please send any comments you have to public-i18n-indic@w3.org . The archive is public, but you need to subscribeto post to it.

Mobile Web Apps roadmap illustrtion

A deliverable of the HTML5Apps project, the October 2014 edition of the W3C Standards for Web Applications on Mobileincludes changes and additions since July 2014, notably emerging work such as:

  • the Second Screen Presentation Working Group API to request display of content on an external screen,
  • a draft API from the Web Bluetooth Community Group,
  • Device APIs Working Group work on a generic pattern for sensors APIs,
  • as well as work on an API to manage permissions across other APIs.
