Amazing card hover effect with Tailwind CSS

Recently, I came across a cool effect for cards and posted it on my Twitter. Cards, when hovered over, reveals a cool gradient effect on top of the card. I thought it was a cool effect and wanted to try it out. I tried it out with Tailwind CSS and it worked out pretty well. In this article, we will learn how to create an amazing card hover gradient effect with Tailwind CSS only.

How it works

Code.jsx

<div class="relative flex min-h-screen flex-col justify-center overflow-hidden antialiased bg-white py-6 sm:py-12">
  <div class="absolute inset-0 bg-[url(/img/grid.svg)] bg-center [mask-image:linear-gradient(180deg,white,rgba(255,255,255,0))]"></div>
  <div class="cursor-pointer block group relative z-50 group bg-white px-6 pt-10 pb-8 shadow-xl ring-1 ring-gray-900/5 sm:mx-auto sm:max-w-lg sm:rounded-lg sm:px-10 after:h-[1px] after:w-[200px] after:bg-gradient-to-r after:from-transparent after:via-teal-500 after:to-transparent after:absolute after:-top-[2px] after:left-[65%] after:opacity-0 after:content-[''] hover:after:left-[30%] hover:after:opacity-100  after:transition-all">
    <div class="mx-auto max-w-md">
      <h1 class="text-2xl  font-bold">Hover over me to see magic 💫 </h1>
      <p class="text-base/8 mt-4">
        {" "}
        The phrase "Hover over me to see magic 💫" is a playful and enticing invitation
        for the user to interact with the text. It suggests that there is something
        hidden or surprising that can be revealed by hovering over the text. This
        kind of interactive element can be effective in engaging users and creating
        a more dynamic and memorable user experience. ChatGPT wrote it.{" "}

      </a>
    </div>
  </div>
</div>

For the container, we are using flexbox to vertically and horizontally align the inner card.
The gradient on top appears when the card is hovered over.
We make use of the :after pseudo element to create the gradient effect.

The meaty part

This is where all the magic of gradient hover happens.

Code.jsx

<div
  class="cursor-pointer block group relative z-50 group bg-white px-6 pt-10 pb-8 
    shadow-xl ring-1 ring-gray-900/5 sm:mx-auto sm:max-w-lg sm:rounded-lg sm:px-10 
    after:h-[1px] after:w-[200px] after:bg-gradient-to-r after:from-transparent after:via-teal-500 
    after:to-transparent after:absolute after:-top-[2px] after:left-[65%] after:opacity-0 after:content-[''] 
    hover:after:left-[30%] hover:after:opacity-100  after:transition-all"
>
  {/* Card code inside */}
</div>

First, we create an :after pseudo element with a height of 1px and width of 200px.
We then set the background to gradient-to-r which means the gradient will be from left to right.
The from color is set to transparent and via color to teal-500 which is a Tailwind CSS color.
We set the position to absolute and top to -2px so that the gradient appears on top of the card.
We set the left to 65% so that the gradient appears on the right side of the card.
When the card is hovered, we simply shift the left position to 30% and set the opacity to 100 so that the gradient appears on the left side of the card.
