Have you ever used tooltips or modals for hover effects? I am trying to decide on the best practice for revealing definitions. The intent is to allow a visitor to hover and read the short definition. Inside of that dialogue window, there will be a link that would take the reader to a full glossary definition if they click it. On the desktop, this method is straightforward. On the phone, not so much. I could use a sheet and have it slide in, but sometimes that looks like the page changed, and people click away. Maybe half a slide-in with overflow hidden and scrolling turned on? What are your thoughts?
