Title: Consistent New Hover Effect on "Book Now" Buttons

Issue No. : Fixes #1611

Code Stack : html, css

Close #1611

Description

The "Book Now" button has a smooth 3D flip hover effect:

Initial State: The button is styled with a bold red background (#ff5a5f) and white text, with padding and rounded corners. Hover Effect: On hover, a secondary color layer (#ff787d or #ffa3a6) flips up from below, replacing the original text with a new label. Smooth Transition: The flip effect is achieved with a rotation animation, giving a dynamic yet subtle 3D appearance that draws attention without being distracting.
