While these changes affect the structure of PPO, there are quite a few things that you control! Some of the biggest choices that can make an organization’s site inaccessible are insufficient color contrast, non-descriptive alt text for images, and a lack of captions or alternative content for multimedia. These topics are much bigger than we can fit in a single newsletter, but the following questions are a good place to start:
Is the color of your text easy to read against the background, or are the colors too similar?
Think about regular text, hyperlinks, and buttons. Some websites remove the underline from hyperlinks for stylistic reasons, but this makes the link difficult to distinguish from the rest of the text based on color alone.
Ensuring good contrast makes a significant difference for someone with low vision or colorblindness, as well as someone using their cellphone while outside in direct sunlight.
Do your images have alt text that describes the image to someone who can’t see it?
Web visitors who use screen readers due to low vision or blindness rely on alt text to describe the content of images. This text is also displayed when an image can’t be loaded, providing the description to anyone visiting the site.
PastPerfect Online uses your data to automatically populate the alt text for an image. For images attached to People Biography and Creator records, the image’s Caption field is used. If the Caption is not available, the Name field from the Person or Creator record is used instead. In the four catalogs (Object, Photo, Archive, and Library), the Caption field from the Image Metadata is used. If the Caption is not available, the Title field from the catalog record will be used. If Title is not available, the Object Name field from the catalog record will be used. Finally, if the Object Name is not available, the generic text of “Collection Item” will be used as the alt text.
When sharing supplemental media files, have you provided alternate ways to consume that media?
For example, information that is only provided via audio, like a recorded oral history interview, is essentially nonexistent for someone who is d/Deaf or Hard-of-Hearing, or someone with an auditory processing disorder. Likewise, someone who is in a quiet space where they can’t turn up the volume or may not have functioning speakers available to them will miss out. Adding captions to the video and making a separate transcript available allows all visitors to interact with your content in the way that works best for them.
