Yes, if I wanted to hide the entire menu, but what I was doing here was hiding just one item out of the entire menu. I had a top menu I did not want to show in the mobile view, but had one item I needed for the mobile view so I included it in the main menu for mobile view. I did not want it to display in the main menu for tablet and larger. Does that make sense?
I could have combined the CSS like so:
/*Do not display in Tablet and larger*/
@media (min-width: 768px) {
div#rt-header ul.gf-menu li.item238 {
display: none;
}
}
