This is a tricky question to deal with in wix. I am running into a similar issue when trying to set a static size for my repeater items. Here is a link to my post as well: Setting a fixed height for a repeater | Velo by Wix
It is easy in wix to trigger events on mouseover. See: onMouseIn - Velo API Reference - Wix.com
The problem is wix is very limited in what you can do with the style prop. Furthermore the compiler does not have access to the root dom so you can not use JavaScript to set the cursor style to pointer with element.style.cursor = pointer. See: Style - Velo API Reference - Wix.com
If there is a way to accomplish this I would very much like to know. But from the research I have done it appears that setting styles in wix programmatically is very limited at the current moment.
