Onmouseover detail on a grid

Hi everyone,
I have a question:
would it be possible, when you move the cursor over an element of a grid, you open a modal mask with some additional details and that it disappears when you move the cursor?
Thank you!

I think you must do it onrecord event with html or javascript. like as:

<a  href="buzz.html" title="buzz hover text">

Use javascript on onLoad event. for each element with id (some mask) add onload event.
