Display Block not moving to next line - css

Question

I'm trying to make a responsive nav bar with tailwind. I want to list my nav links with a single item in each row when I open the navigation menu. Right now, they are all on one row. I'm using tailwind:
function Navbar() {
const [isOpen, setIsOpen] = useState(false);
return (
<header>
<div className="flex flex-col max-w-screen-xl px-4 mx-auto md:items-center md:justify-between md:flex-row md:px-6 lg:px-8">
<div className="p-4 flex flex-row items-center justify-between">
<Link href="/">
<a className="text-lg font-semibold tracking-widest text-gray-900 uppercase rounded-lg dark-mode:text-white focus:outline-none focus:shadow-outline">
Header
</a>
</Link>
<button
className="md:hidden rounded-lg focus:outline-none focus:shadow-outline"
onClick={() => {
setIsOpen(!isOpen);
}}
>
Menu
</button>
</div>
<nav className={isOpen ? "flex" : "md:flex hidden"}>
<NavLink pathTo="/" displayText="Home" />
<NavLink pathTo="/" displayText="Page 1" />
<NavLink pathTo="/" displayText="Page 2" />
</nav>
</div>
</header>
);
}
export default Navbar;
My NavLink component is as follows:
import React from "react";
import Link from "next/link";
interface NavItem {
pathTo: string;
displayText: string;
}
function NavLink(item: NavItem) {
return (
<Link href={item.pathTo}>
<a className="block lg:p-4 px-4 py-2 mt-2 border-b-2 border-white text-sm bg-transparent dark-mode:bg-transparent dark-mode:hover:border-red-400 dark-mode:focus:border-red-400 dark-mode:focus:text-white dark-mode:text-gray-200 md:mt-0 md:ml-4 hover:text-gray-900 focus:text-gray-900 hover:border-red-400 focus:border-red-400">
{item.displayText}
</a>
</Link>
);
}
export default NavLink;
What am I missing? I want the NavLinks to have one item on each row when opened from the menu. I thought display:block would do it, but it seems not to. Why's that?

You need to add a flex direction to your nav links. Adding flex-col should do the trick.
