sing Javascript Write a page that displays a balloon (using the balloon emoji, ?). When you press the up arrow, it should inflate (grow) 10 percent, and when you press the down arrow, it should deflate (shrink) 10 percent. You can control the size of text (emoji are text) by setting the font-size CSS property (style.fontSize) on its parent element. Remember to include a unit in the value—for example, pixels (10px). The key names of the arrow keys are "ArrowUp" and "ArrowDown". Make sure the keys change only the balloon, without scrolling the page.
