<p class="text-gray-600">Tailwind CSS is a utility-first CSS framework designed to help developers build custom designs directly in the HTML by applying utility classes. Instead of writing custom CSS or using pre-designed components, Tailwind allows you to compose styles with a collection of predefined classes, making the process of styling faster and more flexible.</p>
<!-- 02. Utility-First CSS Framework -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Utility-First CSS Framework</h2>
<p class="text-gray-600">Tailwind is a utility-first framework, meaning it provides low-level utility classes that allow you to style elements directly in your markup. You can combine multiple utilities to design complex layouts and responsive designs without writing custom CSS. For example, classes like <code>p-4</code> for padding or <code>text-center</code> for centering text are used to apply specific styles to elements.</p>
<!-- 03. Responsive Design -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Responsive Design</h2>
<p class="text-gray-600">Tailwind makes it simple to create responsive web designs. By using <code>responsive modifiers</code>, you can apply different styles based on the screen size. Tailwind comes with built-in breakpoints like <code>sm:</code>, <code>md:</code>, <code>lg:</code>, and <code>xl:</code>, which allow you to design layouts that adjust for mobile, tablet, and desktop views.</p>
<!-- 04. Customization -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Customization</h2>
<p class="text-gray-600">Tailwind CSS is highly customizable. You can configure your project by editing the <code>tailwind.config.js</code> file, where you can define custom colors, breakpoints, spacing, and other design-related settings to match your brand or design system.</p>
<!-- 05. Pre-built Components -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Pre-built Components</h2>
<p class="text-gray-600">While Tailwind is focused on utility classes, it also provides a set of pre-built components through libraries like Tailwind UI. This allows you to quickly integrate UI elements like buttons, forms, and modals without the need to build them from scratch.</p>
<!-- 06. Easy to Use -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Easy to Use</h2>

<!-- 07. Performance -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Performance</h2>

<!-- 10. Minimalism and Purity -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">Minimalism and Purity</h2>

<!-- 11. JIT (Just-In-Time) Mode -->
<h2 class="text-2xl font-semibold text-gray-800 mb-4">JIT (Just-In-Time) Mode</h2>
<p class="text-gray-600">Tailwind CSS introduced JIT mode, which compiles only the classes that are used in your project.
