Basic Utilities

Typography

<h1 class="text-4xl font-bold text-gray-900">
    Large Bold Heading
</h1>

<p class="text-lg text-gray-600 leading-relaxed">
    Paragraph with good readability
</p>

Layout with Flexbox

    <div>Column 1</div>

</div>

Responsive Design

Tailwind uses a mobile-first breakpoint system:

<div class="w-full sm:w-1/2 md:w-1/3 lg:w-1/4">
    Responsive width
</div>

<!-- Breakpoints:
     sm: 640px
     md: 768px

     xl: 1280px
     2xl: 1536px
-->
