How to using underline hover animation in tailwindcss?

Here's a basic example demonstrating how to create an animation where an underline gradually appears on hover:

html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Tailwind CSS Underline Hover Animation</title>
<!-- Import Tailwind CSS -->
<link href="https://cdn.jsdelivr.net/npm/tailwindcss@latest/dist/tailwind.min.css" rel="stylesheet">
<!-- Custom styles -->
<style>
  /* Extend these classes in Tailwind configuration */
  .hover-underline-animation {
    display: inline-block;
    position: relative;
    color: #3490dc;
    text-decoration: none;
  }

  .hover-underline-animation::after {
    content: '';
    position: absolute;
    width: 100%;
    transform: scaleX(0);
    height: 2px;
    bottom: 0;
    left: 0;
    background-color: #3490dc;
    transform-origin: bottom right;
    transition: transform 0.25s ease-out;
  }

  .hover-underline-animation:hover::after {
    transform: scaleX(1);
    transform-origin: bottom left;
  }
</style>
</head>
<body class="flex items-center justify-center h-screen">
  <!-- Underline animation link -->
  <a href="#" class="hover-underline-animation text-xl">
    Hover me to see the underline animation
  </a>
</body>
</html>

In the above code, we define a hover-underline-animation class that can be applied to any element where you want the underline hover animation. This class uses the pseudo-element :after to display the underline on hover and controls the animation effect using the transform property. The transition property ensures the animation is smooth.

You can also leverage TailwindCSS's @apply directive to directly apply utility classes in CSS, or extend your classes through the configuration file tailwind.config.js. These approaches maintain CSS consistency and maximize TailwindCSS's capabilities.

您可以使用组 max-w-{x} 和transition-all 在纯 TailwindCSS 中实现这一点，在跨度上使用组悬停，这样当您经过链接时它就会启动动画

shell
<a href="#" class="group text-sky-600 transition duration-300">
Link
<span class="block max-w-0 group-hover:max-w-full transition-all duration-500 h-0.5 bg-sky-600"></span>
</a>
