Hover-Triggered and Focus-Triggered Content

One of the many interaction patterns that we can take for granted is the ability to trigger the hiding or showing of content on pointer hovers, such as with tooltips or spoiler-covered text or images. This comes up most often with data visualizations but can also often be seen with menu items, additional help dialogs, and more. There are some tips and tricks we can use to make elements like tooltips a little better. However, ultimately, hover-triggered content is just not an accessible pattern. Our best bet is to use a different approach or provide an alternate source, in addition to the hover-triggered content, to communicate the same information.
