This is possibly a really really dumb question, but why does the button result in a vertical gap in the grid when using a div doesn't? ```jsx import React from "react"; import "./styles.css"; export default function App() { const images = [1, 2, 3, 4, 5, 6,7,8,9]; const aspectRatio = "16/9"; return ( <ul className="group grid transform grid-cols-5 gap-1"> {images.map((image, index) => ( <li key={image} style={{ aspectRatio }} className="cols-span-1 relative transform duration-200 hover:!scale-110 group-hover:scale-100" > <button className="relative h-full w-full" onClick={() => setCurrentImageIndex(index)} > <div className="h-full w-full bg-red-500"></div> </button> </li> ))} </ul> ); }```
