How to make VPNavBar transparent on a custom landing page

[alephpi]

By default NavBar is only transparent when layout:home what if I design a fully customized landing page with layout: false, where I directly import VPNavBar of the default theme, how can I make it transparent? If I write something like <VPNav class="bg-transparent"/>, nothing seems happen

well I use a very dirty workaround that set layout:home and use a customized MyLayout to render the customized landing page when layout:home, therefore the imported VPNav would behave just as if it is on a home page.
