checking boxes doesn’t work, neither css i inserted in quick CSS:

@media screen and (min-width: 480px) {.page-id-78 .hide_slider_mobile1 {display: none;} }
@media screen and (max-width: 480px) {.page-id-78 .hide_slider_mobile {display: none;} }

i copied .page-id-78 .hide_slider_mobile1 into slider custom class but nothing happens…
