Quirks Mode refers to a technique used by some web browsers for the sake of maintaining backward compatibility with web pages designed for older browsers. When a page is rendered in quirks mode, the browser mimics the behavior of older versions to display outdated or non-standard code correctly. It’s like reading a book with outdated spelling or grammar but still understanding the meaning because you’re familiar with the context and conventions of that time.
