How to Add a Linear Gradient Border to a Button in Tailwind CSS

Creating visually appealing UI elements is crucial for modern web development. One popular effect is adding a linear gradient border to buttons. In this guide, you'll learn how to achieve this using Tailwind CSS, with examples and explanations.

Solution with Code

To create a button with a linear gradient border in Tailwind CSS, follow the steps below:

Basic Gradient Border

This example uses a parent container to apply the gradient and creates an inner button to simulate the border.

<button class="rounded bg-gradient-to-r from-blue-500 to-purple-500 p-1 font-semibold text-white">
  <span class="flex w-full rounded bg-gray-900 p-2 text-white">Gradient Border Button</span>
</button>

Explanation:

1. bg-gradient-to-r from-blue-500 to-purple-500: Sets a linear gradient from blue to purple.
2. p-1: Adds padding to create space for the gradient border.
3. span: The inner button with a solid background color to simulate the effect of a gradient border.

Adding Hover Effects

To make the button more interactive, you can use hover effects.

<button class="relative overflow-hidden rounded bg-gradient-to-r from-green-400 via-blue-500 to-purple-600 p-1">
  <span class="flex h-full w-full transform items-center justify-center rounded bg-gray-900 text-white transition-transform duration-300 hover:scale-105">
    Hover Me
  </span>
</button>

Key Points:

• relative and overflow-hidden: Ensure the gradient stays in place.
• transition-transform and hover:scale-105: Add a smooth scaling effect on hover.

Complete Example with Next.js

  return (
    <Link href="/about">

        <span className="absolute inset-0 rounded-full border-2 border-transparent bg-gradient-to-r from-pink-500 via-red-500 to-yellow-500"></span>
      </button>
    </Link>
  )
}
