el rollover no se puede ver en tabletas ni móviles

Rollovers are not supported for HTML output.

For touch screens, use onClick instead of onMouseover.

Rollovers will work on mobile devices, but there is a 300ms delay as the software translates what should be done, (same as using click instead of touch to activate).

The best way to use rollover effects on the web is to use css transform/transitions. That way once something is touched it will 'go through the motions', similar to a hover. There is a big but here though, in that unless one ties it to a css animation, it may 'stick' in the rollover position.

I agree with BarbBinder though, in that if one does not know what they are doing with such effects, and is not 'translating' them to touch actions for mobile devices, don't use them.

What Adobe software are you using?

Web UI mistake 1: Using rollovers
