rummaged and found that it was connected with .mc_item, but I didn’t understand how to solve the problem ...
what is the phenomenon and how to solve it?
The goal is to make 140 px and so that there is no stripe.
Thank you!

Answer 1

.mc_item_wrap {height: 140px;} тут не изменили высоту

.mc_item {height: 140px;}

Answer 2

And the same for :hover

li.mc_item_wrap .mc_item:hover { background-color: ...; }
