As I mentioned above, under each WCAG 2.1 principle is a list of guidelines, and under each guideline are compliance standards, with techniques and failure examples at each level. Some guidelines include only Level A items; others include items for multiple levels of conformance, building from A to AAA. At each stage, you can easily see what more you would need to do to reach Level AA or AAA. In this way, many websites include elements at multiple levels of accessibility.
What’s the scope of the work? Will the website be basic with just a few pages about your company, its services, and contact information? Or will it also have an e-commerce section for online shopping, a blog, or content for visitors to download? Before you hire a web designer, make sure you have a thorough, specific list of the components you must have the designer include in the web design.
That’s good news if you are one of the many Americans who have a visual, hearing, or mobility disability that makes it difficult to access some information on the web. If you are a business owner who hasn’t made provisions to ensure that your website and other online assets are ADA compliant, you could be looking at a host of legal and financial penalties.
I was educated at the Illinois Institute of Art in Chicago and have over decade of graphic design experience developing t-shirts, posters, flyers, illustrations, web graphics, and many more. All of my work delivers on creating high quality images filled with detail and color. My belief in establishing a good relationship as well as excellent communication with each of my clients helps me produce the professional work they are looking for. My ambitious nature and need to create fuels my drive to always deliver the best for my clients.
Blind people, those with low vision, and people with other disabilities that affect their ability to read a computer display often use different technologies so they can access the information displayed on a webpage. Two commonly used technologies are screen readers and refreshable Braille displays. As discussed above, a screen reader is a computer program that speaks the text that appears on the computer display, beginning in the top-left corner. A refreshable Braille display is an electronic device that translates text into Braille characters that can be read by touch. These assistive technologies read text. They cannot translate images into speech or Braille, even if words appear in the images. For example, these technologies cannot interpret a photograph of a stop sign, even if the word “stop” appears in the image.
These and other types of multimedia can present two distinct problems for people with different disabilities. People who are deaf or hard of hearing can generally see the information presented on webpages. But a deaf person or someone who is hard of hearing may not be able to hear the audio track of a video. On the other hand, persons who are blind or have low vision are frequently unable to see the video images but can hear the audio track.
HTML tags – specific instructions understood by a web browser or screen reader. One type of HTML tag, called an “alt” tag (short for “alternative text”), is used to provide brief text descriptions of images that screen readers can understand and speak. Another type of HTML tag, called a “longdesc” tag (short for “long description”), is used to provide long text descriptions that can be spoken by screen readers.
The words in the tag should be more than a description. They should provide a text equivalent of the image. In other words, the tag should include the same meaningful information that other users obtain by looking at the image. In the example of the mayor’s picture, adding an “alt” tag with the words “Photograph of Mayor Jane Smith” provides a meaningful description.
