[Share] Add a non-clickable text to top of header

If you can't make it work, you can send site url, I will check again.

#1. To add a non-clickable text to top of header, you can use this code to Custom CSS box

header#header:before {
    content: "Add something here";
    display: block;
    text-align: center;
    font-size: 16px;
    margin-top: 10px;
    margin-bottom: 10px;
}

Result

#2. To make this text appears on One Page only.

First, you need to find Page ID. Use below tool.

In my example, we will have: #collection-66aef2caff007776a825a948

Next, use this CSS code

body:not(#collection-66aef2caff007776a825a948) header#header:before {
	display: none !important;
}

#3. To make text appears on Mobile only, use this CSS code

@media screen and (min-width:768px) {
	header#header:before {
		display: none !important;
}
}

#4. To make text appears on Desktop Only, use this CSS code

@media screen and (max-width:767px) {
header#header:before {
		display: none !important;
}
}
