Transparent Drop-Down only on the home page

[SemereClothing]

Hello everyone,
I have made my dropdown menu in the header transparent with the following code.

details[open] > .header__submenu {
  background-color: transparent !important;
  border: none !important;
}
.header-wrapper * {
  color: white !important;
}

However, now I would like to have it on product pages, category pages etc. with a black background and have a white font (only on the homepage transparent). Is it also possible to have a separator in white in between like in thepicture? Thanks for your help!
