"Eliminate all instances of the blue button without introducing any new ones." One way to achieve this would be to use the following CSS: ``` .blue-button { display: none; } ``` This would hide all blue buttons from view, without affecting any other elements on the page. Another way to achieve this would be to use the following JavaScript: ``` var blueButtons = document.querySelectorAll('.blue-button'); for (var i = 0; i < blueButtons.length; i++) { blueButtons[i].remove(); } ``` This would remove all blue buttons from the page, without affecting any other elements on the page. In either case, the blue buttons would be completely eliminated from the page, without any new ones being created.
