Understanding Utility Classes

Utility classes in Tailwind CSS are small, single-purpose classes that you can apply directly to HTML elements to style them. Each utility class corresponds to a specific CSS property and value, allowing you to build custom designs quickly without writing custom CSS.

Key Characteristics

• Each utility class does one thing, such as setting a margin, padding, color, or font size;
• You can combine multiple utility classes to achieve complex styles;
• Using predefined utility classes ensures consistent styling across your project;
• Tailwind provides responsive variants of utility classes to handle different screen sizes easily.

Example

Explanation

1. p-4 adds padding of 1rem (16px) on all sides;

3. text-white sets the text color to white;
4. text-xl sets the font size to a larger size;
5. font-bold makes the text bold;
6. mt-2 adds a top margin of 0.5rem (8px).
