Create a Mobile Slider Menu

https://www.mickthewpmentor.com.au/create-a-mobile-slider-menu-in-elementor/

I used to use this css to make a moblie slider menu when I was using Elementor Pro.
Can I make something like this in GenerateBlocks Pro?

@media screen and (max-width: 768px) {
.mickmenu .elementor-nav-menu--layout-horizontal .elementor-nav-menu {
display: flex;
flex-wrap: nowrap;
white-space: nowrap;
overflow-x: auto;
-webkit- -scrolling: touch;
-ms-overflow-style: -ms-autohiding-scrollbar;
}
}
