Hi @weribinc,
Please change the CSS code to make the header transparent to be restricted only for the pages, something like this:
body.page-template .x-navbar, body.page-template .x-navbar .sub-menu {
background-color: hsla(0,0%,12%,0) !important;
}
If you check the code of the page you will see that the theme adds the page-template class to the HTML BODY tag whenever a page is showing.
1- I have found the proper CSS code selector using the Chrome browser Developer Toolbar:
