FLATIRON How to add a text ONLY at the top of an INDEX page

I would like to add a short text ONLY at the top of the following Index page:

https://www.emmanuellemoureaux.com/100colors

I want the text appears ONLY at the top of this Index page and not also at EACH page composing this Index page.

(When clicking each photo ot this Index thumbnail, I don't want that the text appears anymore)

If you have a solution, it would be greatly appreciated.

Thank you.

I believe because it's a Portfolio style page in 7.0, this isn't possible, even with custom code. The text is inputted on the page itself, but then applies to each additional page because they're all in the same collection. I'd need access so I can try to do it for you, if you want me to try feel free to message!

Add this custom css code:

To hide text inside pink section on all page:

.sqs-announcement-bar-custom-location {

display: none !important;

}

/* To show text inside pink section only in "100colors" page */

#collection-54acafbbe4b0f1bacf9d5f21 .sqs-announcement-bar-custom-location {

display: block !important;

}

It will be like the screen-shot attached.
