have a problem with 2 headers

hii i have a problem with my page.. you see im using the Customizing Additional CSS of the editor and doing some changes with my page and i have 2 headers 1 is called header1 and the other header2 but here is the thing header1 is for the index only and header2 for all the rest and i remember that in the css part you could insert the code of the header that you want to implement and the header that you want to be hidden like this:

.page-id-32 “part of the header1 that i want to delete” {
display: none;
}
&
.page-id-32 “part of the header2 that i want to be shown” {
display: block;
}

but i don’t remember what to do in this case ‘cus i don’t remember what to put in those parts
