Hello, the submenu of my main navbar is currently too wide, and spans underneath another section (in this case, “About Us”):

I am able to adjust the width through the Inspector Tool successfully:

but when I write the code in the actually Global CSS editor, nothing happens.
This is how I’m targeting the submenu:
.desktop .submenu {
width: 160px;
}
with 160px being the desired width, as opposed to the default at 200px. What am I doing wrong?
