There are two types of menus in Pure.CSS:

Vertical menu
Horizontal menu
Pure.CSS provides vertical menus by default. You can change the vertical menu to horizontal menu by adding the class name “pure-menu-horizontal”.

For a Pure.CSS interview question about Pure.CSS menus, the correct answer would be:

Pure.CSS menus are a part of the Pure.CSS framework, which is a lightweight set of responsive CSS modules that can help in developing web interfaces quickly and efficiently. Pure.CSS menus specifically refer to the navigation menus or dropdown menus created using Pure.CSS classes and styles. These menus are designed to be simple, lightweight, and easy to customize, providing a clean and minimalist appearance while ensuring responsiveness across various devices and screen sizes. They typically involve the use of Pure.CSS classes like pure-menu, pure-menu-list, pure-menu-item, and others to structure and style the menu elements effectively.
