Electric Voltage Button Effect with SVG and CSS Animation
Looking to add a high-voltage, animated button effect to your website? This advanced CSS and SVG button design will bring a dynamic spark animation that lights up on hover. Perfect for tech sites, developer tools, or creative UI portfolios — this button effect goes beyond traditional styles with glowing outlines, electric trails, and animated spark particles.
What is the Voltage Button?
The voltage button is a creatively animated HTML and CSS button that:
Changes background color on hover.
Triggers animated electric sparks using SVG strokes.
Reveals glowing dots that rise and fall like voltage particles.
Uses CSS filters and
feDisplacementMapto simulate distortion.
When hovered, the button feels alive — sparking energy around its border and showing movement through animated paths and particles.
How the Effect is Built
1. HTML Structure
The button is wrapped inside a .voltage-button container, followed by:
An SVG element containing animated paths (
line-1andline-2) to simulate electrical movement.A
.dotscontainer holding small divs that animate like rising or falling energy sparks.
2. SVG Spark Animation
The SVG paths are animated using stroke-dasharray and stroke-dashoffset along with @keyframes:
spark-1andspark-2animations simulate the moving electric lines.A
glowfilter adds a glowing blur and displacement for realism.
3. Hover Triggers
The button:hover state:
Changes the button background to a deeper blue.
Triggers the
svgand.dotsto appear by increasing their opacity.Starts the spark animations and dot motions.
4. Flying Dots Animation
Each dot uses fly-up or fly-down animation:
Dots rise or fall while fading in and out.
Each dot has its own animation delay, creating a scattered, random effect.
Why This Button Stands Out
SVG Power: It’s a rare example of using SVG animation and CSS filters in harmony.
No JavaScript Needed: Everything runs on HTML and CSS, making it lightweight.
Highly Customizable: You can easily change colors, speed, dot count, and effects.
Modern Visual Appeal: It adds an electric, futuristic vibe to any project.
Use Cases for Voltage Button
This animated voltage-style button works best for:
Developer tools and SaaS websites.
High-tech product launches or apps.
Personal portfolios for UI/UX designers.
Cyberpunk or science-fiction themed interfaces.
How to Customize It
You can easily tweak the look and behavior:
Change spark colors by editing
strokein.line-1and.line-2.Adjust animation speed in the
@keyframessection.Modify dot positions and add more for a denser effect.
Replace the button text with call-to-action phrases like “Download,” “Start Now,” or “Try Demo.”
