const accordionHeaders = document.querySelectorAll(".accordion-header");

accordionHeaders.forEach((header) => {
  header.addEventListener("click", function () {
    // Toggle the active class on the header
    this.classList.toggle("active");

    // Get the associated content element
    const content = this.nextElementSibling;

    // Toggle the display of the content
    if (content.style.display === "block") {
      content.style.display = "none";
    } else {
      content.style.display = "block";
    }
  });
