How to Create a Spotlight Card Hover Effect with Tailwind CSS

Spotlight effect with Tailwind CSS

Welcome to this tutorial where we’ll take you on a journey to create an eye-catching spotlight card hover effect using Tailwind CSS. If you’re new to this trending effect, we recommend checking out the live demo or our Dark Next.js landing page template called Stellar.

To begin, we’ll create the spotlight card using pure HTML and vanilla JavaScript. After that, we’ll take it a step further by showing you how to create a reusable component for Next.js and Vue.

Let’s get started!

Create the spotlight effect with HTML and vanilla JavaScript

As we usually do in our tutorials, we will start by creating a basic HTML document that will contain the structure of our animation. Then we will write the JavaScript code in an external JS file.

<!DOCTYPE html>
<html lang="en"> <head> <meta charset="utf-8"> <title>Spotlight Effect</title> <meta name="viewport" content="width=device-width,initial-scale=1"> <link rel="preconnect" href="https://fonts.googleapis.com"> <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin> <link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700;800&display=swap" rel="stylesheet"> <script src="https://cdn.tailwindcss.com"></script> <script> tailwind.config = { theme: { extend: { fontFamily: { inter: ['Inter', 'sans-serif'], }, }, }, }; </script>
</head> <body class="relative font-inter antialiased"> <main class="relative min-h-screen flex flex-col justify-center bg-slate-900 overflow-hidden"> <div class="w-full max-w-6xl mx-auto px-4 md:px-6 py-24"> <!-- Cards container --> <div class="max-w-sm mx-auto grid gap-6 lg:grid-cols-3 items-start lg:max-w-none group"> <!-- Card 1 --> <!-- Card 2 --> <!-- Card 3 --> </div> <!-- End: Cards container --> </div> </main> <script src="./spotlight-effect.js"></script>
</body> </html>

We’ve created a very simple structure, with a container that will hold our cards. Now let’s start with coding one card, and then we’ll duplicate it to create the other two.

<div class="relative h-full bg-slate-800 rounded-3xl p-px before:absolute before:w-80 before:h-80 before:-left-40 before:-top-40 before:bg-slate-400 before:rounded-full before:opacity-0 before:pointer-events-none before:transition-opacity before:duration-500 before:translate-x-[var(--mouse-x)] before:translate-y-[var(--mouse-y)] before:group-hover:opacity-100 before:z-10 before:blur-[100px] after:absolute after:w-96 after:h-96 after:-left-48 after:-top-48 after:bg-indigo-500 after:rounded-full after:opacity-0 after:pointer-events-none after:transition-opacity after:duration-500 after:translate-x-[var(--mouse-x)] after:translate-y-[var(--mouse-y)] after:hover:opacity-10 after:z-30 after:blur-[100px] overflow-hidden"> <!-- 1.

After pseudo element --> </div>

We’ve added a lot of classes to the card, but don’t worry, we’ll go through them one by one.

Add a card border

In our first div, we’ve added a bg-slate-800 to define a dark background color. Then, we’ve added a p-px class to add a 1px padding to the card, and the card content has the same background color of the page. Doing that, we’re creating a fake 1px border around the card.

The reason why we’re not using conventional CSS borders is that they won’t allow us to create the effect we want to achieve.

Now, let’s move on with the before and after pseudo elements. We will use the before and after prefixes provided by Tailwind CSS to create them, and define their style.

The before pseudo element will be used to lighten the borders of our cards on mouse hover, while the after pseudo element will be used for the spotlight effect above the card.

Use the before pseudo element for the card border

Let’s see how it works the before pseudo element. It’s a layer placed below the card content, and it’s absolutely positioned to cover the entire card. It’s visible for 1px on the card sides, and that “lightens” the card borders with a lighter gray color (slate 400) on mouse hover.

The key Tailwind CSS classes of this element are:

before:opacity-0 before:group-hover:opacity-100: the before pseudo element is hidden by default, and it’s visible only when the card container is hovered. Note that we’re using a Tailwind CSS group-hover variant, so you want to make sure to add the group class to the card parent element.
before:translate-x-[var(--mouse-x)] before:translate-y-[var(--mouse-y)]: this class defines the position of the before pseudo element. We’re using Tailwind’s arbitrary properties to set the translate-x and translate-y CSS properties to the mouse position. This way, the before pseudo element will follow the mouse cursor.

Use the after element for the spotlight

The after pseudo element is used to create the spotlight effect. It’s a layer placed above the card content, and it’s absolutely positioned to cover the entire card.

The code looks much like the before pseudo element, but there are a few differences:

The blurred circle looks a bit bigger (after:w-96 after:h-96)
The background color is different (after:bg-indigo-500) and the target opacity is lower (after:hover:opacity-10)
We’ll make the spotlight appear when hovering the single card, not the card container as we did for the before pseudo element

Cool! Now, when you hover the card, you should see the spotlight effect and the card borders lightening in the top left corner.

As you may guess, we want to animate the spotlight effect, so let’s add some JavaScript.

Make the spotlight follow the mouse cursor

As you already know, we used translate-x-[var(--mouse-x)] and translate-y-[var(--mouse-y)] to set the position of both before and after pseudo element. In other words, we used --mouse-x and --mouse-x CSS variables to set the position of the elements instead of using a fixed value.

Now we want to update the value of those CSS variables on mouse move, so that the spotlight will follow the mouse cursor. We’ll use a bit of JavaScript to do that.

Let’s create a JavaScript class called Spotlight inside our spotlight-effect.js file:

// Cards spotlight
class Spotlight { constructor(containerElement) { this.container = containerElement; this.cards = Array.from(this.container.children); this.mouse = { x: 0, y: 0, }; this.containerSize = { w: 0, h: 0, }; this.initContainer = this.initContainer.bind(this); this.onMouseMove = this.onMouseMove.bind(this); this.init(); } initContainer() { this.containerSize.w = this.container.offsetWidth; this.containerSize.h = this.container.offsetHeight; } onMouseMove(event) { const { clientX, clientY } = event; const rect = this.container.getBoundingClientRect(); const { w, h } = this.containerSize; const x = clientX - rect.left; const y = clientY - rect.top; const inside = x < w && x > 0 && y < h && y > 0; if (inside) { this.mouse.x = x; this.mouse.y = y; this.cards.forEach((card) => { const cardX = -(card.getBoundingClientRect().left - rect.left) + this.mouse.x; const cardY = -(card.getBoundingClientRect().top - rect.top) + this.mouse.y; card.style.setProperty('--mouse-x', `${cardX}px`); card.style.setProperty('--mouse-y', `${cardY}px`); }); } } init() { this.initContainer(); window.addEventListener('resize', this.initContainer); window.addEventListener('mousemove', this.onMouseMove); }
} // Init Spotlight
const spotlights = document.querySelectorAll('[data-spotlight]');
spotlights.forEach((spotlight) => { new Spotlight(spotlight);
});

We won’t go into the details of the code, but here’s a quick overview of what it does:

It creates a Spotlight instance for each element with the data-spotlight attribute, which is supposed to be the container holding the cards
When hovering the card container, it sets --mouse-x and --mouse-y CSS variables on each card
It updates --mouse-x and --mouse-y values on mouse move, but only if the mouse cursor is inside the card container

That way, the translate-x and translate-y values of the before and after pseudo elements will be updated on mouse move, and the spotlight will follow the mouse cursor.

Finally, ensure to add the data-spotlight attribute to the card container, and add the cards as first-level children of the container:

Create a reusable Spotlight component for Next.js

Now that we have a working spotlight effect, let’s create a reusable component for Next.js with TypeScript support. The component we are going to build is available in our GitHub repository that includes all Next.js examples from our tutorials.

Let’s create a new file called spotlight.tsx inside the components folder. Since we have a container and some cards inside it, we are going to create two components for them:

Spotlight is the main component, and it handles the full logic.
SpotlightCard is just a wrapper for the card content. It accepts a className prop that will be applied to the card container, and a children prop that will be the card content.

'use client' import React, { useRef, useState, useEffect } from 'react'
import useMousePosition from './utils/mouse-position' type SpotlightProps = { children: React.ReactNode className?: string
} export default function Spotlight({ children, className = '',
}: SpotlightProps) { const containerRef = useRef<HTMLDivElement>(null) const mousePosition = useMousePosition() const mouse = useRef<{ x: number; y: number }>({ x: 0, y: 0 }) const containerSize = useRef<{ w: number; h: number }>({ w: 0, h: 0 }) const [boxes, setBoxes] = useState<Array<HTMLElement>>([]) useEffect(() => { containerRef.current && setBoxes(Array.from(containerRef.current.children).map((el) => el as HTMLElement)) }, []) useEffect(() => { initContainer() window.addEventListener('resize', initContainer) return () => { window.removeEventListener('resize', initContainer) } }, [setBoxes]) useEffect(() => { onMouseMove() }, [mousePosition]) const initContainer = () => { if(containerRef.current) { containerSize.current.w = containerRef.current.offsetWidth containerSize.current.h = containerRef.current.offsetHeight } } const onMouseMove = () => { if (containerRef.current) { const rect = containerRef.current.getBoundingClientRect() const { w, h } = containerSize.current const x = mousePosition.x - rect.left const y = mousePosition.y - rect.top const inside = x < w && x > 0 && y < h && y > 0 if (inside) { mouse.current.x = x mouse.current.y = y boxes.forEach((box) => { const boxX = -(box.getBoundingClientRect().left - rect.left) + mouse.current.x const boxY = -(box.getBoundingClientRect().top - rect.top) + mouse.current.y box.style.setProperty('--mouse-x', `${boxX}px`) box.style.setProperty('--mouse-y', `${boxY}px`) }) } } } return ( <div className={className} ref={containerRef}>{children}</div> )
} type SpotlightCardProps = { children: React.ReactNode, className?: string
} export function SpotlightCard({ children, className = ''
}: SpotlightCardProps) { return <div className={`relative h-full bg-slate-800 rounded-3xl p-px before:absolute before:w-80 before:h-80 before:-left-40 before:-top-40 before:bg-slate-400 before:rounded-full before:opacity-0 before:pointer-events-none before:transition-opacity before:duration-500 before:translate-x-[var(--mouse-x)] before:translate-y-[var(--mouse-y)] before:group-hover:opacity-100 before:z-10 before:blur-[100px] after:absolute after:w-96 after:h-96 after:-left-48 after:-top-48 after:bg-indigo-500 after:rounded-full after:opacity-0 after:pointer-events-none after:transition-opacity after:duration-500 after:translate-x-[var(--mouse-x)] after:translate-y-[var(--mouse-y)] after:hover:opacity-10 after:z-30 after:blur-[100px] overflow-hidden ${className}`}>{children}</div>
}

As you can see, the code looks much like the one we used in the previous section. We’ve just added some TypeScript annotations, and imported the mouse-position.tsx component – that we previously created for another tutorial – to get the mouse position.

We can now import and use them in a page or in another component, just like this:

Create a Vue Spotlight component

As a final step, we are going to create a reusable component for Vue with TypeScript support, that is available in our GitHub repository, which includes all the examples from the Cruip tutorials.

Let’s create a new file called Spotlight.vue inside the components folder.

<script setup lang="ts">
import { ref, onMounted, onBeforeUnmount, reactive, watch } from 'vue'
import useMousePosition from './utils/MousePosition' const containerRef = ref<HTMLCanvasElement | null>(null)
const mousePosition = useMousePosition()
const mouse = reactive<{ x: number; y: number }>({ x: 0, y: 0 })
const containerSize = reactive<{ w: number; h: number }>({ w: 0, h: 0 })
const boxes = ref<any[]>([]) onMounted(() => { if (containerRef.value) { boxes.value = Array.from(containerRef.value.children) } initContainer() window.addEventListener('resize', initContainer)
}) onBeforeUnmount(() => { window.removeEventListener('resize', initContainer)
}) watch( () => mousePosition.value, () => { onMouseMove() }
) const initContainer = () => { if (containerRef.value) { containerSize.w = containerRef.value.offsetWidth containerSize.h = containerRef.value.offsetHeight }
} const onMouseMove = () => { if (containerRef.value) { const rect = containerRef.value.getBoundingClientRect() const { w, h } = containerSize const x = mousePosition.value.x - rect.left const y = mousePosition.value.y - rect.top const inside = x < w && x > 0 && y < h && y > 0 if (inside) { mouse.x = x mouse.y = y boxes.value.forEach((box) => { const boxX = -(box.getBoundingClientRect().left - rect.left) + mouse.x const boxY = -(box.getBoundingClientRect().top - rect.top) + mouse.y box.style.setProperty('--mouse-x', `${boxX}px`) box.style.setProperty('--mouse-y', `${boxY}px`) }) } }
}
</script> <template> <div ref="containerRef"> <slot></slot> </div>
</template>

As you can see, we are using the MousePosition.ts component – that we previously built for the particle animation tutorial – which gets the mouse coordinates.

Then, we need a separate component for each box, which we are going to call SpotlightCard.vue:

<template> <div class="relative h-full bg-slate-800 rounded-3xl p-px before:absolute before:w-80 before:h-80 before:-left-40 before:-top-40 before:bg-slate-400 before:rounded-full before:opacity-0 before:pointer-events-none before:transition-opacity before:duration-500 before:translate-x-[var(--mouse-x)] before:translate-y-[var(--mouse-y)] before:group-hover:opacity-100 before:z-10 before:blur-[100px] after:absolute after:w-96 after:h-96 after:-left-48 after:-top-48 after:bg-indigo-500 after:rounded-full after:opacity-0 after:pointer-events-none after:transition-opacity after:duration-500 after:translate-x-[var(--mouse-x)] after:translate-y-[var(--mouse-y)] after:hover:opacity-10 after:z-30 after:blur-[100px] overflow-hidden"> <slot></slot> </div>
</template>

Finally, we can use the Spotlight.vue and SpotlightCard.vue components in our pages:

<Spotlight class="max-w-sm mx-auto grid gap-6 lg:grid-cols-3 items-start lg:max-w-none group"> <!-- Card #1 --> <SpotlightCard> <div class="relative h-full bg-slate-900 p-6 pb-8 rounded-[inherit] z-20

What do you think of the final result? Isn’t it beautiful? We personally love it, and we’re not surprised that in 2023 the spotlight card hover effect has become extremely popular, as it manages to make any design look fresher and more modern.

Feel free to apply this effect anywhere you want, and also test it on a white background if you think it may be more consistent with your designs.
