Introduction
Symbols speak louder than words, and the heart is the most universal symbol of all. In this Neon Heart Animation project, we are taking this classic shape and giving it a high-tech, vibrant makeover. We aren't just drawing a heart; we are breathing life into it. This project focuses on simulating a Realistic Heartbeat Pulse combined with a glowing neon light effect. It's a perfect project for learning how to synchronize multiple CSS properties (like scale, blur, and color) to create a single, unified "breathing" animation that feels natural and emotionally resonant.
How It Works
The heartbeat effect is achieved using a complex CSS Keyframe sequence. Unlike a simple pulse that goes in and out, a real heartbeat has a double-thump rhythm (lub-dub). We replicate this by setting keyframes at 0%, 15%, 30%, and 100%. To create the neon glow, we use a combination of drop-shadow and filter: brightness(). As the heart expands (the "beat"), the shadow's blur radius increases and the color becomes more intense. This creates the illusion that the heart is actually emitting light that reflects off a digital surface. By using relative sizing (em/rem), we ensure the heart remains perfectly centered and crisp on any device.
Key Features of Project
- Biometric Rhythm: Perfectly timed "double-beat" animation for a realistic feel.
- Soft Neon Glow: Multi-layered shadows create a premium, non-jagged light effect.
- Pure CSS Logic: No JavaScript required for the main animation, making it extremely lightweight (under 2KB).
- Customizable Intensity: Control how "bright" the neon heart glows by adjusting a single CSS variable.

Conclusion
Building the Neon Heart Animation is a great exercise in timing and visual effects. It shows how CSS alone can create deeply engaging and polished animations without the need for complex libraries. Use this heart to add some "love" to your next project, whether it's a dating app, a health tracker, or just a fun personal site. Keep coding with heart!
