The Web Experience Toolkit (WET) includes reusable components for building and maintaining innovative websites that are accessible, usable, and interoperable. Unlike previous versions, WET allows developers to package and optimize their JavaScript, CSS and plugins. This final build folder can be used by publishers to style and provide functionality to their websites.

The following documentation provides new users and contributors with the resources needed to create a website using WET.

Why WET?

WET is a toolkit which includes reusable components that can be used by web professionals to build websites. WET complies with the Web Standards released by the Government of Canada, and helps sites that employ it achieve compliance. It is also an open source project which is free to use and contribute to through GitHub.


  • Focus is on mobile development.
  • Simpler calling system for plugins.
  • CSS standardization and optimization.
  • More CMS friendly.
  • Provides reusable components.
  • Respects accessibility (WCAG 2.0 AA and WAI-ARIA), usability, and interoperability principles.
  • Reduces costs by providing re-usable Web tools and solutions.
  • Open source software that is free to use.
  • Uses advanced technologies, such as:
    • HTML5, CSS3, jQuery (JavaScript framework);
    • Ever-growing list of open source plugins and widgets; and
    • Supports a wide range of layouts and designs.

Main Components

  • WET Core Framework: The WET Core Framework includes functionality used in all WET pages. This includes jQuery plugins and CSS, JavaScript for processing mobile views and external libraries.
  • Base CSS: Every WET site uses a series of base CSS classes which are not theme dependent.
  • CSS Grid System: The grid system is CSS to style the content of the page using grids. It also includes additional CSS styles for the content area of Government of Canada websites.
  • Theming: Themes are composed of theme-specific style sheets, images and jQuery.
  • Mobile support: WET allows pages to display differently on mobile devices.
  • i18n localization system: Language integration file which translates key words based on the language specified in html lang attribute.
