Solved make the main menue transparent only on first page

Hey,

I would like to have the main menu on top of my site transparent only on the first page.
I set the main menue background to white using the theme customizer.

When I use the following css code for one specific page it works fine:

#main-header {
background: red;
}

but I would like to have something like

#main-header {
background: transparent;
}

but this doesn't work. The background color remains white.

Can you give me a hint what to do here?

 

ok, after using google and trying it out for a while I guess I found the solution. Just place this code to the page you need the effect:

#main-header {
background-color: transparent;
box-shadow: 0 0 0 rgba(0,0,0,.1);
}

#page-container {
padding-top:0px!important;
}
