Tailwind CSS Utilities Overview

Introduction

• Tailwind CSS is easy to learn, as classes map directly to CSS properties.
• Beyond basics, Tailwind has features like dark mode, light mode, and more.
• This presentation covers 10 Tailwind utilities that enhance functionality beyond single CSS properties.

1. Container Class

• Purpose: Creates a responsive container.
• Default Behavior: Not centered and no padding.
• Customization:
  • Use mx-auto to center the container.
  • Add padding using px-4.
  • Set default behavior in Tailwind config by enabling centering and padding.

2. Size Class

• Purpose: Sets both height and width simultaneously.
• Usage: Instead of w-48 h-48, use size-48 for a square shape.

3. Divide Utility

• Purpose: Adds dividing lines between elements without repeating border styles.
• Usage: Apply divide-y or divide-x to a parent container to separate child elements.
• Customization: Change the color using Tailwind's color classes (e.g., divide-red-500).

4. Space Utility

• Purpose: Adds space between child elements without using Flexbox or Grid.
• Usage: Use space-y-4 on a parent element to space out children vertically.

5. Line Clamp

• Purpose: Restricts text to a specified number of lines and adds ellipses for overflow.
• Usage: Use line-clamp-3 to limit text to three lines.

6. Truncate Utility

• Purpose: Ensures text does not wrap to more than one line and adds ellipses for overflow.
• Usage: Apply truncate to maintain a single line of text.

7. Gradients

• Purpose: Easily create gradient backgrounds.
• Usage: Specify colors using from, via, and to properties (e.g., bg-gradient-to-r from-orange-500 to-black).
• Customization: Adjust the position of colors in the gradient.

8. Ring Utility

• Purpose: Adds a focus ring around elements using box shadows.
• Usage: Use ring class for a ring effect (e.g., ring-4). Can combine with borders.

9. Built-in Animations

• Purpose: Simple animations for elements (e.g., spin, ping, pulse, bounce).
• Usage: Use classes like animate-spin for built-in animations.

10. Screen Reader Utilities

• Purpose: Control visibility of elements for screen readers.
• Usage: sr-only hides elements visually but keeps them accessible.
• Customization: Use not-sr-only to make elements visible again.
