Utility-First CSS Explained
Understand the utility-first approach and why Tailwind applies single-purpose classes directly in HTML instead of writing custom CSS.
What Is a Utility Class?
A utility class does exactly one styling job. Instead of writing custom CSS, you stack tiny classes right in your HTML, like p-4 bg-white rounded-lg.
<div class="p-4 bg-white rounded-lg">
This is a card.
</div>The Utility-First Philosophy
Tailwind is utility-first: you style straight in HTML with small classes instead of naming things in a CSS file. Faster building, no jumping between files.
