Change text “search here…”

Hello ivory i cannot change the text in the search bar.
When i go into your default search form, and write my text in the TEXT BOX PLACEHOLDER box. it still doesn’t change the text.

I have also tried to write code to change the text.

::placeholder {
visibility: hidden;
}

::placeholder :before {
content: “Søg her”;
visibility: visible;
}

But this only removes the text “Search here…” And does not change it.
