This example shows a playful, static web page dedicated to SV Werder Bremen, with a large green message and a light blue button that toggles the message’s color to pink when clicked. The page uses plain HTML, CSS, and vanilla JavaScript, with the button’s event listener calling `classList.toggle` to switch the `pink` class on both elements. No external libraries or data sources are involved; the layout relies entirely on CSS Grid for centering and fixed styling, while the JavaScript handles the simple interactive state change.
