Dropdown Css [ UPDATED ]

.dropdown__menu li a display: block; padding: 0.5rem 1rem; color: #1e293b; text-decoration: none; transition: background 0.15s;

(JavaScript can toggle data-open ; CSS-only arrow change requires :focus-within plus sibling selectors — omitted for brevity.) For mobile, convert absolute positioning to full-width block: dropdown css

.dropdown:hover .dropdown__menu, .dropdown:focus-within .dropdown__menu, .dropdown__menu:hover opacity: 1; visibility: visible; transform: translateY(0); .dropdown__menu li a display: block

.dropdown__trigger:focus-visible outline: 2px solid #3b82f6; outline-offset: 2px; padding: 0.5rem 1rem
