Tailwind Widgets

What Are Widget Components?

Widget components are self-contained, reusable UI elements that perform specific functions or display particular types of information. Examples include:

• Cards: Display content such as text, images, and actions in a contained layout.

• Buttons: Trigger actions or navigation.

• Modals: Overlay dialogs for user interactions.

• Alerts: Provide feedback or important information to users.

• Navbars: Navigation bars for website or application navigation.

Creating these components with Tailwind allows for rapid development and ensures consistency across your application.

Why Use Tailwind for Widget Components?

• Utility-First: Tailwind's utility classes enable precise control over styling without writing custom CSS.

• Customization: Easily customizable via the tailwind.config.js file.

• Responsive Design: Built-in responsive utilities make it simple to create mobile-friendly components.

• Consistency: Enforces a consistent design system across components.

• Performance: Purges unused CSS in production, keeping the CSS bundle size minimal.

Common Widget Components with Tailwind

1. Card Component

A card component is versatile and commonly used to display content in a structured format.

Example:

<div class="max-w-sm rounded overflow-hidden shadow-lg bg-white">
  <img class="w-full h-48 object-cover" src="<https://via.placeholder.com/400x300>" alt="Image">
  <div class="px-6 py-4">
    <div class="font-bold text-xl mb-2">Card Title</div>
    <p class="text-gray-700 text-base">
      This is a brief description of the card content. It provides some insights or information.
    </p>
  </div>
  <div class="px-6 pt-4 pb-2">
    <span class="inline-block bg-blue-200 rounded-full px-3 py-1 text-sm font-semibold text-blue-700 mr-2 mb-2">#tag1</span>
    <span class="inline-block bg-blue-200 rounded-full px-3 py-1 text-sm font-semibold text-blue-700 mr-2 mb-2">#tag2</span>
    <span class="inline-block bg-blue-200 rounded-full px-3 py-1 text-sm font-semibold text-blue-700 mr-2 mb-2">#tag3</span>
  </div>
</div>

Explanation:

• Container: max-w-sm sets the maximum width, rounded applies border-radius, shadow-lg adds a shadow, and bg-white sets the background color.

• Image: w-full makes the image take full width, h-48 sets height, and object-cover ensures the image covers the area.

• Content: Padding utilities (px-6 py-4) and typography classes.

• Tags: Styled with background color, rounded corners, padding, and margin utilities.

2. Button Component

Buttons are essential for user interactions. Tailwind allows you to create various button styles.

Example:

<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Button Text
</button>

Explanation:

• Background: bg-blue-500 sets the button color, and hover:bg-blue-700 changes it on hover.

• Text: text-white for white text, font-bold for bold text.

• Padding: py-2 px-4 for vertical and horizontal padding.

• Borders: rounded for rounded corners.

3. Modal Component

Modals overlay content on the current page and are typically used for dialogs, forms, or additional information.

Example:

<!-- Trigger Button -->
<button id="openModal" class="bg-green-500 hover:bg-green-700 text-white font-bold py-2 px-4 rounded">
  Open Modal
</button>

<!-- Modal Backdrop -->
<div id="modal" class="fixed inset-0 flex items-center justify-center bg-black bg-opacity-50 hidden">
  <!-- Modal Content -->
  <div class="bg-white rounded-lg shadow-lg w-11/12 md:w-1/3">
    <div class="flex justify-between items-center p-4 border-b">
      <h2 class="text-xl font-semibold">Modal Title</h2>
      <button id="closeModal" class="text-gray-600 hover:text-gray-800">&times;</button>
    </div>
    <div class="p-4">
      <p>This is the modal content. You can place forms, text, or other components here.</p>
    </div>
    <div class="flex justify-end p-4 border-t">
      <button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
        Close
      </button>
    </div>
  </div>
</div>

<!-- JavaScript to Toggle Modal -->
<script>
  const openModal = document.getElementById('openModal');
  const modal = document.getElementById('modal');
  const closeModal = document.getElementById('closeModal');

  openModal.addEventListener('click', () => {
    modal.classList.remove('hidden');
  });

  closeModal.addEventListener('click', () => {
    modal.classList.add('hidden');
  });

  // Close modal when clicking outside the content
  window.addEventListener('click', (e) => {
    if (e.target === modal) {
      modal.classList.add('hidden');
    }
  });
</script>

Explanation:

• Backdrop: fixed inset-0 covers the entire viewport, flex items-center justify-center centers the modal, bg-black bg-opacity-50 adds a semi-transparent background, and hidden initially hides the modal.

• Modal Content: Styled with bg-white, rounded-lg, shadow-lg, and responsive widths.

• Header: Flex layout with title and close button.

• JavaScript: Simple script to toggle visibility.

4. Alert Component

Alerts provide users with feedback or important information.

Example:

<div class="flex items-center bg-yellow-100 border-l-4 border-yellow-500 text-yellow-700 p-4" role="alert">
  <svg class="w-6 h-6 mr-4" fill="currentColor" viewBox="0 0 20 20">
    <path d="M2.93 17.07A10 10 0 1 1 17.07 2.93 10 10 0 0 1 2.93 17.07z"/>
    <path d="M9 9h2v6H9V9zm0-4h2v2H9V5z"/>
  </svg>
  <div>
    <p class="font-bold">Warning</p>
    <p>There was a problem processing your request.</p>
  </div>
</div>

Explanation:

• Container: flex items-center for alignment, bg-yellow-100 for background, border-l-4 border-yellow-500 for a colored left border, and padding.

• Icon: SVG icon with size and margin.

• Text: Bold title and description.

5. Navbar Component

Navbars are crucial for site navigation and branding.

Example:

<nav class="bg-gray-800">
  <div class="max-w-7xl mx-auto px-4">
    <div class="flex items-center justify-between h-16">
      <!-- Logo -->
      <div class="flex-shrink-0">
        <a href="#" class="text-white text-xl font-bold">MyLogo</a>
      </div>
      <!-- Menu -->
      <div class="hidden md:block">
        <div class="ml-10 flex items-baseline space-x-4">
          <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">Home</a>
          <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">About</a>
          <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">Services</a>
          <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">Contact</a>
        </div>
      </div>
      <!-- Mobile menu button -->
      <div class="-mr-2 flex md:hidden">
        <button id="mobileMenuButton" class="inline-flex items-center justify-center p-2 rounded-md text-gray-400 hover:text-white hover:bg-gray-700">
          <svg class="h-6 w-6" stroke="currentColor" fill="none" viewBox="0 0 24 24">
            <path id="menuIcon" class="inline-flex" stroke-linecap="round" stroke-linejoin="round" stroke-width="2"
              d="M4 6h16M4 12h16M4 18h16"/>
          </svg>
        </button>
      </div>
    </div>
  </div>
  <!-- Mobile Menu -->
  <div id="mobileMenu" class="md:hidden hidden">
    <div class="px-2 pt-2 pb-3 space-y-1 sm:px-3">
      <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">Home</a>
      <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">About</a>
      <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">Services</a>
      <a href="#" class="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">Contact</a>
    </div>
  </div>
</nav>

<!-- JavaScript to Toggle Mobile Menu -->
<script>
  const mobileMenuButton = document.getElementById('mobileMenuButton');
  const mobileMenu = document.getElementById('mobileMenu');

  mobileMenuButton.addEventListener('click', () => {
    mobileMenu.classList.toggle('hidden');
  });
</script>
