What is meant by web accessibility?
Web accessibility is the application of design principles to make websites, web applications, and web content usable by persons with disabilities who may be using assistive technologies to access the web.
What design principles were considered to make the NCDB website accessible?
- Separation of content and design - all of the visual elements on the website (e.g. menu bars, avatars, images, logos, colored elements like bars and badges) can be removed without detracting from the textual content of the site.
Descriptive image tags - all images used within the NCDB site have associated descriptions so that individuals who are visually impaired that are using a screen reader can still understand the purpose and context of the image.
High contrast - text and visual information is presented in a high contrast environment (e.g. black text on white background, white text on red background) so that text is always easy to read.
No reliance on color to convey information - color used throughout the site is for aesthetic or decorative purposes. It is not intended to convey important information.
Video captioning - we caption all videos presented on our website.
How do you know that the NCDB website is indeed accessible?
We periodically run several pages of the website through an accessibility test website http://wave.webaim.org/. We then correct any accessibility shortcomings that this tool shows us. Also, before launching the site, we had several people using assistive technologies browse our site and alert us to problems.
If I post content on the NCDB website through a forum or wiki, does it need to be accessible too?
Yes. Text information submitted in blogs, forums, comments to the forum and in wikis will rely on the design elements built into the site to handle accessibility. Issues may occur with the images, videos, and files that are uploaded. There are tools included in the site that help to make this content more accessible. You may want to browse some accessibility guidelines to ensure that your content is compliant. In general, make sure that you do the following when creating content:
- Provide descriptive tags for images
- Once the image is loaded, clicking on the image will bring up the dialog box
- Add a descriptive title and this will serve as a descriptive tag for screen readers
Do not use Flash animation for important content
If there are questions, contact the Site Administrator.
If I upload documents or other files to one of my groups, must these files be accessible?
Yes. This is especially true for items in public groups. There may be different allowances in private groups depending on work scope and member preferences.
If I post a link to another site, must that site also be accessible?
The NCDB website links to content frequently housed on other websites and that content may not always be accessible. However, the user and their potential accessibility issues should always be foremost in your mind when linking to other sites. Again, contact the NCDB Site Administrator if you have questions about our site.
What do I do if I have trouble accessing some content on the NCDB website?
If you use assistive technology (such as a Braille reader, a screen reader, etc.) and the format of any material on our web pages interfere with your ability to access the information, please contact the NCDB Site Administrator. To enable us to respond in a manner most helpful to you, please indicate the nature of your accessibility problem, the preferred format in which to receive the material, the web address of the requested material, and your contact information. The website may contain links to external publications and web sites. Links are provided as a service to our audience, in an effort to provide additional information where applicable. NCDB has no control over the accessibility of these non-NCDB publications and external websites.
