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
Images can be added to exhibit pages (Home, Featured, About) using page widgets that embed exhibit items (Item Row, Carousel, Slideshow, and Grid widgets) or the Uploaded Item Row widget.
...
If embedding an exhibit item to your page as an image, you can set custom image alt text by using the "Alt text" field.
...
If you do not set this field, the alt text will default to your item's title.
Using the alt text is recommended when the item's title is not unique. A unique alt text helps screen readers distinguish between different items on a page.
The Alt text field is not available for the Item Embed widget.
Uploaded Image
When uploading an image using the Uploaded Item Row widget, use the "Caption" field instead. This is especially important when you also add a "Link Url".
...
If embedding a YouTube video with user-generated captions, you can add ?cc_load_policy=1&cc_lang_pref=en to the end of your YouTube embed URL to display captions on the video by default. This will not work with automatically-generated captions. For more information, see: YouTube Help: Embed videos & playlists.
Vimeo
Vimeo also provides iframe embed code to enable caption display by default. For example, to enable the display of automatically generated english captions, you would add &texttrack=en-x-autogen to your Vimeo embed URL. For more information, see: Vimeo Help Center: Enable captions and subtitles in embeds by default.
