Excluding code from portfolio subpages

Hi,

I have applied a portfolio page which is acting as my home page. On this page I have customised the header to be sticky so that it appears under a video on loading the page and as you scroll down it sticks to the top. This works perfect on the home page but it is the only page that i want it to appear. It doesnt happen on the contact us or about page however at the moment it is appearing on the portfolio subpages which are linked to the home page. Does anyone know how to exclude this style from appearing on the subpages. Below is the code I have currently

<style>
@media screen and (min-width: 768px) {
#header {
  position: sticky;
  top: 0;
  display: none;
  z-index: 10000;
}
main .page-section:first-child + #header {
  display: block;
}
main .page-section:first-child {
  min-height: calc(100vh - 93px)!important;
}
}
</style>

Hi @BryanMinton, instead of placing this code in the header injection, you could put it in the Custom CSS and target it to the page Collection ID, that way it would only affect the homepage.

If you can share your website URL and site wide password if applicable then I can provide you with the full CSS.

I have applied it to the home page settings in the pages tab. Is it better to move this to the custom css in design instead?

Yes, it can be. Though you could add the Page ID to the code where you have it.
