Accessibility

Screen Readers

To assist our visitors who are visually impaired or blind, our website is compatible with screen reading software.

Code Compliance

This site was built using code compliant with W3C standards for HTML and CSS. Standards compliant code means that the site displays correctly in current browsers and ensures that it will display correctly in future browsers.

Text Alternative

With the exception of decorative imagery, all non-text content presented to the user has a text alternative that serves the equivalent purpose. Screen readers can then present this alternate information to the user in place of the image.

ARIA Landmarks

We use ARIA landmarks to identify regions of the page allowing those with screen readers to jump to different sections of the page.

Skip to Main Content

Our pages all contain a skip to main content link allowing users to jump directly to the page's main content, avoiding the header content from being read aloud repeatedly.

Accessible Forms

Our forms have the proper markup to associate labels with their form controls making it easier for screen readers to present the form information to the user.

Headings and Lists

We use the proper markup for headings and lists, i.e. h1–h6 and ol, ul and dl for lists. Heading markup allows assistive technologies to present the heading status of text to a user. Some assistive technologies allow users to navigate from list to list or item to item.

CSS

We use CSS to control visual presentation of text. This allows users to modify, via the user agent, the visual characteristics of the text to meet their requirement — including size, color, font family and relative placement.

Resizing Text

Text can be resized without assistive technology up to 200 percent without loss of content or functionality.

Raster Images

We avoid the use of text in raster images. This allows user agents to read aloud any text on the page and apply custom style sheets to make the text more legible.

Keyboard Interface

The site is designed with consideration for people unable to use a mouse. The website can be navigated using your keyboard or other assistive devices. All functionality is operable through a keyboard interface without requiring specific timings for individual keystrokes, supporting speech input software and on-screen keyboards.

Flashing Content

Web pages do not contain anything that flashes more than three times in any one second period, or the flash is below the general flash and red flash thresholds. These effects are known to cause seizures if the flashes are bright and large enough.

Page Titles

Our web pages have titles that describe topic or purpose. Descriptive titles help users find content, orient themselves within it, and navigate through it. When descriptive titles are used within link text, they help users navigate more precisely to the content they are interested in.

Locating Content

More than one way is available to locate a Web page within a set of Web pages. We provide breadcrumbs and site maps, making it possible for users to locate content in a manner that best meets their needs.

Highlighting

The majority of our website components allow for highlighting by the user agent when they receive focus.

Default Language

The default human language of each Web page can be programmatically determined. Speech synthesizers that support multiple languages will be able to orient and adapt to the pronunciation and syntax specific to the language of the page.

Component Focus

When any of our components receive focus, they do not initiate a change of context — forms are not submitted automatically when a component receives focus, and new windows are not launched when a component receives focus.

Consistent Navigation

We maintain consistent navigation across our web pages. This technique makes the placement of navigational components more predictable.

Form Input Errors

In forms, if an input error is automatically detected, the item that is in error is identified and the error is described to the user in text.

Proper Coding

Elements have complete start and end tags, are nested according to their specifications, do not contain duplicate attributes, and any IDs are unique — ensuring compatibility with assistive technologies when parsing content.
