How do you set up a fixed header using Tailwind CSS?
Description : You can create a fixed header by using the `fixed` class with `top-0`.
Answer :
Apply `fixed top-0 left-0 w-full` to the header. For example:`<header class='fixed top-0 w-full bg-white shadow'>Header content</header>`. This makes the header fixed at the top of the page with full width.
