<div class="flex">
    <aside class="h-screen sticky top-0">
        // Fixed Sidebar
    </aside>

    <main>
        // Content
    </main>
</div>

What do you think about mentioning about it in README?

This doesnt handle all the cases. In fact, i came looking for this library because that method above does not work for me.

doesn't work when your sidebar bigger than viewportHeight
