Mastering the Cyberpunk Glitch Effect: A Pure CSS Tutorial (Line-by-Line Breakdown)

Ahmod Musa — Wed, 21 Jan 2026 15:42:07 GMT

Have you ever looked at the UI of Cyberpunk 2077 or classic sci-fi movies and admired those glitchy, glowing neon signs?

It creates a "High Tech, Low Life" vibe that is incredibly popular right now for gaming sites, developer portfolios, and creative landing pages.

Today, we are going to build that exact effect.

The best part? We are doing it with Pure CSS. No JavaScript libraries, no heavy images. Just clean code.

Let’s break down the logic behind the "Glitch."

1. The HTML Structure (The Skeleton)

We start with a simple anchor tag. However, there is one specific attribute you need to pay attention to: data-text.

Why data-text? To create a glitch effect, we need two layers of the same text: the "Real" layer and the "Glitch" layer. Instead of writing the text twice in HTML (which is bad for SEO), we use data-text. CSS will grab this value later to create the ghost layer automatically.

2. The Base Styling (The Neon Look)

First, let's give the button that futuristic Cyan glow. We use a combination of box-shadow and text-shadow.

.cyber-link {
  position: relative; /* Parent for absolute pseudo-elements */
  text-decoration: none;
  font-size: 24px;
  color: #00f7ff; /* The classic Cyberpunk Cyan */
  border: 2px solid #00f7ff;
  padding: 20px 40px;
  text-transform: uppercase;
  letter-spacing: 4px; /* Wide spacing looks more cinematic */
  font-weight: bold;
  overflow: hidden; /* Hides anything outside the border */
  transition: 0.2s;
/* The Neon Glow Magic */
text-shadow: 0 0 5px #00f7ff;
box-shadow: 0 0 10px #00f7ff, inset 0 0 5px #00f7ff;
}

Key Takeaway: The inset property in box-shadow makes the glow appear inside the button as well, giving it a glass-tube neon feel.

3. The Scanline Texture (Retro TV Vibe)

Old monitors have scanlines. We can simulate this texture using the ::before pseudo-element and a CSS gradient.

.cyber-link::before {
  content: '';
  position: absolute;
  top: 0; left: 0; width: 100%; height: 100%;
/* Creating the stripes /
background: repeating-linear-gradient(
0deg,
transparent,
transparent 2px,
rgba(0, 247, 255, 0.1) 3px,
rgba(0, 247, 255, 0.1) 4px
);
z-index: -1; / Place it behind the text /
pointer-events: none; / Ignore mouse clicks */
}

This creates subtle, transparent stripes across the button, adding depth and texture to the flat color.

4. The Glitch Layer (Where the Magic Happens)

Now for the complex part. We use ::after to create a copy of the text using content: attr(data-text). We color it Magenta (Pink) to contrast with the Cyan.

.cyber-link::after {
  content: attr(data-text); /* Grabs text from HTML */
  position: absolute;
  top: 0;
  left: -2px; /* Offset it slightly to the left */
  width: 100%; height: 100%;
  padding: 20px 40px;
  background: #050505;
  color: #ff00ea; /* Glitch Color (Magenta) */
  border: 2px solid #ff00ea;
  z-index: -2;
  opacity: 0; /* Hidden by default */
/* Slicing the text */
clip-path: polygon(0 20%, 100% 20%, 100% 50%, 0 50%);
}

What is clip-path? Imagine taking a pair of scissors and cutting a strip out of the text. That is what clip-path does here. It only shows a specific slice of the pink text.

5. Hover & Animation (Action!)

When the user hovers over the link, we want three things to happen:

The background fills up.
The "Glitch Layer" becomes visible.
The Glitch Layer starts shaking/jerking randomly.

/* Invert colors on hover */
.cyber-link:hover {
  background: #00f7ff;
  color: #050505;
  box-shadow: 0 0 30px #00f7ff; /* Super bright glow */
  text-shadow: none;
}
/* Reveal and animate the glitch */
.cyber-link:hover::after {
opacity: 1;
left: 4px;
animation: glitch-jerk 0.3s linear infinite alternate;
}

The Keyframes: This animation rapidly changes the clip-path (the slice position) and moves the text left and right (transform: translate).

@keyframes glitch-jerk {
  0% {
    clip-path: polygon(0 20%, 100% 20%, 100% 50%, 0 50%);
    transform: translate(0);
  }
  50% {
    clip-path: polygon(0 30%, 100% 30%, 100% 60%, 0 60%);
    transform: translate(-2px); /* Jerk Left */
  }
  100% {
    clip-path: polygon(0 10%, 100% 10%, 100% 40%, 0 40%);
    transform: translate(2px); /* Jerk Right */
  }
}

Conclusion

The beauty of this effect is that it looks complex, but it relies on standard CSS properties like clip-path and pseudo-elements.

Create a 3D Cyberpunk Glitch Card using CSS & JS (No Libraries)

Ahmod Musa — Thu, 01 Jan 2026 17:08:20 GMT

There is something undeniably cool about the Cyberpunk aesthetic. The neon lights and high-tech vibe scream future. In this tutorial, we will build a Cyberpunk Glitch Card that feels like it was ripped straight out of a sci-fi game UI.

The result? A 3D Interactive Profile Card that reacts to your mouse movement and features a jagged, glitching text animation.

In this tutorial, I’m going to show you exactly how I built it. We will use CSS clip-path for the angled corners and a few lines of JavaScript for that smooth 3D tilt effect.

Why Build a Cyberpunk Glitch Card?

This isn't just a static image. Here is what makes this card special:

Holographic Glitch Text: I used CSS keyframes and the clip property to make the text look like it's malfunctioning.
3D Tilt Effect: The card follows your mouse cursor in a 3D space.
Angled UI: Using clip-path, we cut the corners of the card to give it that sharp, industrial sci-fi look.

Demo

The Source Code You can copy-paste the code below to use this card in your own portfolio or project.

Below is the complete source code for the Cyberpunk Glitch Card. You can copy-paste it directly into your project.

1. The HTML Structure We need a container for the 3D perspective and a wrapper for the glitch effect on the avatar. Notice the data-text attribute on the title—that's the secret to the glitch effect!

2. The CSS (The Magic) This is where the heavy lifting happens. I used CSS variables for the Neon Cyan and Pink colors so you can easily change the theme. The @keyframes glitch-anim handles the text distortion.

@import url('https://fonts.googleapis.com/css2?family=Orbitron:wght@400;700;900&family=Share+Tech+Mono&display=swap');

:root {
    --primary: #00f3ff; /* Cyan Neon */
    --secondary: #ff0055; /* Pink Neon */
    --bg: #050505;
    --card-bg: #111;
}

.card:hover .corner { width: 100%; height: 100%; opacity: 0.1; }

/* --- Keyframes --- */
@keyframes glitch-anim {
    0% { clip: rect(10px, 9999px, 30px, 0); transform: skew(0.5deg); }
    10% { clip: rect(50px, 9999px, 70px, 0); transform: skew(0.2deg); }
    20% { clip: rect(20px, 9999px, 60px, 0); transform: skew(0.8deg); }
    100% { clip: rect(80px, 9999px, 100px, 0); transform: skew(0.1deg); }
}
@keyframes glitch-anim-2 {
    0% { clip: rect(60px, 9999px, 80px, 0); transform: skew(0.6deg); }
    10% { clip: rect(10px, 9999px, 30px, 0); transform: skew(0.3deg); }
    100% { clip: rect(90px, 9999px, 100px, 0); transform: skew(0.1deg); }
}

3. The JavaScript (The Interaction) We don't need a heavy library like Three.js here. A simple event listener tracking the xAxis and yAxis of the mouse is enough to create a realistic tilt.

const card = document.getElementById('cyber-card');

document.addEventListener('mousemove', (e) => {
    let xAxis = (window.innerWidth / 2 - e.pageX) / 20;
    let yAxis = (window.innerHeight / 2 - e.pageY) / 20;

    card.style.transform = `rotateY(${xAxis}deg) rotateX(${yAxis}deg)`;
});

card.addEventListener('mouseenter', () => {
    card.style.transition = 'none';
});

card.addEventListener('mouseleave', () => {
    card.style.transition = 'all 0.5s ease';
    card.style.transform = `rotateY(0deg) rotateX(0deg)`;
});

How the "Glitch" Works If you look at the CSS for .cyber-title, you will see I used ::before and ::after pseudo-elements. These elements contain the exact same text as the title (grabbed via attr(data-text)).

By positioning them slightly apart and animating their clip property rapidly, we create the illusion that the text is splitting and twitching. It’s a classic trick, but it works perfectly for this style.

Conclusion Building UI components like this is a great way to practice modern CSS properties like clip-path and transform-style. Plus, it looks awesome on a developer portfolio!

Feel free to grab the code, change the colors, and make it your own. If you build something cool with it, tag me—I’d love to see it.
