I noticed that most mobile browsers transform rollovers into touch/tap actions. This is good, but of course there's no indicator that the action is available to the user. So I was wondering what should be the best approach when developing websites:
Avoid rollovers altogether (mobile and desktop)
Disabled rollovers on mobile only.
Instead of using rollovers on mobile, display the rollover content under or on the side
Add visual clues/indicators on mobile that an object has a rollover/touch state
