Abstract Dropdown menus remain a critical UI component for navigation and form inputs. This paper presents a CSS-only approach to building accessible, responsive, and visually consistent dropdowns without JavaScript, leveraging pseudo-classes, transitions, and the :focus-within selector. 1. HTML Structure A semantic foundation ensures accessibility and styling hooks. .dropdown__trigger:focus-visible outline: 2px solid #3b82f6

:focus-within keeps the dropdown open when tabbing into menu items, enabling full keyboard accessibility. 4. Arrow Rotation & State .dropdown[data-open="true"] .dropdown__arrow transform: rotate(180deg); .dropdown__menu:hover opacity: 1

.dropdown__menu li a:hover, .dropdown__menu li a:focus-visible background-color: #f1f5f9; outline: none;
