Hello,
Left arrow has opacity if it’s inactive to inform users that click does not work (when you can’t click the arrow because there is no slide before). Are you sure that you want to remove this opacity in this case? If yes then replace the previous code with this one
.mpc-carousel__wrapper:hover .mpc-nav-preset–default .mpc-nav__arrow i:hover,
.mpc-navigation .mpc-nav__arrow.slick-disabled .mpc-nav__icon {
opacity: 1 !important;
}
Do you want to add padding between blocks?
Regards
