My goal is to insert a blurry header background and a blurry dropdown-menu. Basically I'm trying to put a Backdrop-filter: blur(15px); to my .dropdown-menu but there's already a Backdrop-filter: blur(5px); inside the header. I believe it's overriding it (not sure).
I've tried using a higher z-index value for the dropdown menu and setting the backdrop-filter property on both the header and dropdown menu, but the issue persists. It's possible that there may be other CSS properties affecting the backdrop-filter property. It would be helpful to provide a minimal, reproducible example of the issue. Thank you.
Here's the code:
// Burger-bar and dropdown menu
const toggleBtn = document.querySelector(".burger-bar");
const toggleBtnIcon = document.querySelector(".burger-bar i");
const dropdownMenu = document.querySelector(".dropdown-menu");
toggleBtn.onclick = function () {
dropdownMenu.classList.toggle("open");
const isOpen = dropdownMenu.classList.contains("open");
toggleBtnIcon.classList = isOpen ? "fa-solid fa-xmark" : "fa-solid fa-bars";
