First Input Delay (FID) is a user experience metric that measures the time it takes for a web page to respond to the first user interaction. Specifically, it quantifies the delay between when a user first interacts with a page (e.g., clicking a button, tapping a link (https://thepopeyesmenu.com/), or pressing a key) and when the browser starts processing that interaction.
