Spotlight provides out-of-the-box accessibility support for exhibits when possible, but exhibit curators are ultimately responsible for ensuring their content is accessible. While there is no one-size-fits-all set of instructions for CUL exhibits, below are a few tips and considerations for improving the accessibility of your CUL exhibit.

Images

uploaded images: caption
embedded exhibit items: "Alt text" or item title - images displaying with the IIIF viewer (e.g. Item Embed Widget) are not currently able to display with alt text.

Videos

Videos embedded on CUL exhibits can typically only be made as accessible as the video uploader allows. If the video uploader has not enabled captions or transcripts, the video will not be able to be embedded with captions or transcripts. Consider uploading only videos that have subtitles enabled. Non-automatically generated subtitles are typically more accurate. For more information about transcribing videos for captioning: https://vimeo.com/blog/post/how-to-transcribe-a-video/

YouTube and Vimeo videos can be embedded on CUL Exhibit pages via the Video Widget or the Iframe Widget. Videos hosted on other platforms (e.g. Kaltura) are only embeddable via the Iframe Widget. If you'd like to automatically display captions by default (assuming the video uploader has provided captions), consider adding the video using the Iframe widget instead of the Video widget. See below for more details.

Iframes

The Iframe widget is a powerful tool for embedding third party content into a CUL exhibit, and it is up to CUL exhibit curators to ensure this content is accessible. If it seems like the content has insufficient color contrast, contains images with no alt text, has poorly formatted html, or other accessibility issues (WCAG 2.1), don't embed it on your exhibit!

There are also certain attributes in the Iframe code itself that can impact the accessibility of content that exhibit curators should keep an eye out for:
