The layout design that Cleartrip.com uses is called a "Sidebar Navigation" layout. It is a common design pattern for websites and applications where the primary navigation menu is located on the left-hand side of the screen and additional content or options are displayed on the right-hand side of the screen. This layout is also sometimes referred to as a "Two-Column Layout" or "Split Screen Layout". The purpose of this layout is to make navigation easier for users, as they can quickly access different sections of the website or application without having to navigate through multiple pages.
