how to show hover on listing items on home page

hello mark, i wonder how to set a hover showing text “more details” or text of the description when hovering on an item on home page.

this is the portfolio examples from richards – https://premiumwebservices.co.uk

you can see at the “tour guides” column when hovering on each category “sleep, eat, shop, do” it will show some description.

How to do that.. please help. thanks
