But i need that for better UX, how can i block other product for stability when i hover other product?
Other products can’t be “blocked” if the height of previous items was changed. Height was changed because of the use “padding-bottom” value. Unfortunately, a design that you want to achieve is cant be done with only CSS code. It requires customizations that are out of our theme support scope.
As an alternative, we recommend you to use “Show summary on hover” product style, which has a similar hover design.
Kind Regards
