What are the best practices for tooltips on mobile websites? I'm designing the mobile version of a website for customers' accounts (where they can see their latest bill and settings for their accounts). The desktop site is filled with tooltips: to explain terms. For instance, on a page to edit customers' settings, there are tooltips for each setting (each setting can also be ticked). We also have customers' bill pages: accounting terms have tooltips.
We're considering tooltips (an 'i' icon next to each item, but each "i" will have to be quite small: not really usable), or a single tooltip button at the top or/and bottom of each page needing tooltip. Or a tooltip pinned to the bottom of the page.
I think we need to minimise the number of tooltips. In addition, I'm not sure what is the best practice, usability-wise, to present them on a mobile device.
