Dropdown menus play a crucial role in web design, providing users with a convenient way to access additional options or navigate through a website's content hierarchy.

Approach
- The HTML structure and CSS classes used in this code are designed to create a responsive dropdown menu. Tailwind CSS provides utility classes for responsive design, allowing the menu to adapt to different screen sizes.
- Each dropdown menu is represented by a button element styled with Tailwind CSS classes for padding, background color, text color, and rounded corners. This button serves as the trigger to toggle the visibility of the dropdown menu.
- Each dropdown menu is implemented as a hidden div element positioned absolutely relative to its parent container. The menu items are styled as anchor elements within this div. Tailwind CSS classes are used for styling, including text color, background color on hover, and shadow effects.
- JavaScript functions are provided to toggle the visibility of each dropdown menu when the corresponding button is clicked. This functionality allows users to show or hide the dropdown menu by clicking the associated button.
- The dropdown menus include a fade-in animation using CSS keyframes. This animation provides a smooth transition when the menu becomes visible, enhancing the user experience.
