1) A responsive website automatically changes its layout and appearance based on the size of the screen it is displayed on, allowing for an optimal viewing experience across different devices.
2) Responsive sites can make text larger and buttons easier to press on smaller screens. They can also hide or present different information depending on the device.
3) The key benefits of responsive websites include providing a consistent user experience and branding across devices, reducing development costs by only needing one website, improving visibility and usability on mobile, and ensuring the site remains optimized as mobile usage increases.
