👉 The newsletter fluid is a responsive design feature that adjusts the layout and content of a newsletter based on the size of the recipient's screen, ensuring an optimal viewing experience across various devices. It uses CSS media queries to detect the viewport width and applies different styles accordingly, such as altering font sizes, column widths, and image placements. This fluid approach guarantees that the newsletter remains visually appealing and easy to read on phones, tablets, and desktops, providing a seamless reading experience regardless of the device used.
