Why Sticky header and footer in Tailwind? - Purpose & Use Cases

The Big Idea

What if your website's menu and footer could follow you smoothly as you scroll, without any tricky hacks?

The Scenario

Imagine you build a website where the top menu and bottom info bar should always stay visible as you scroll down a long page.

The Problem

If you try to fix the header and footer by manually adjusting margins or using old tricks, they might overlap content or disappear when scrolling, making the page confusing and hard to use.

The Solution

Sticky headers and footers use CSS positioning to keep these areas fixed in place, so they stay visible without blocking content or needing constant manual tweaks.

Before vs After

✗ Before

<header>Menu</header>
<div>Content here</div>
<footer>Info</footer>

✓ After

<header class="sticky top-0 bg-white">Menu</header>
<div>Content here</div>
<footer class="sticky bottom-0 bg-white">Info</footer>

What It Enables

This lets users always access navigation or important info, improving site usability and making your design look polished and professional.
