Designing the Button with CSS
Next, we’ll style our button using CSS. This will include setting up the background, text, and adding transitions.
body {
display: flex;
align-items: center;
justify-content: center;
min-height: 100vh;
background: linear-gradient(to bottom, #323232 0%, #3F3F3F 40%, #1C1C1C 150%), linear-gradient(to top, rgba(255, 255, 255, 0.40) 0%, rgba(0, 0, 0, 0.25) 200%);
background-blend-mode: multiply;
}
.sparkle-button {
--active: 0;
--bg: radial-gradient(40% 50% at center 100%, hsl(270 calc(var(--active) * 97%) 72% / var(--active)), transparent), radial-gradient(80% 100% at center 120%, hsl(260 calc(var(--active) * 97%) 70% / var(--active)), transparent), hsl(260 calc(var(--active) * 97%) calc((var(--active) * 44%) + 12%));
background: var(--bg);
font-size: 1.2rem;
font-weight: 500;
border: 0;
cursor: pointer;
padding: 1em 1em;
display: flex;
align-items: center;
gap: 0.25em;
white-space: nowrap;
border-radius: 100px;
position: relative;
box-shadow: 0 0 calc(var(--active) * 3em) calc(var(--active) * 1em) hsl(260 97% 61% / 0.75), 0 0em 0 0 hsl(260 calc(var(--active) * 97%) calc((var(--active) * 50%) + 30%)) inset, 0 -0.05em 0 0 hsl(260 calc(var(--active) * 97%) calc(var(--active) * 60%)) inset;
transition: box-shadow var(--transition), scale var(--transition), background var(--transition);
scale: calc(1 + (var(--active) * 0.1));
transition: 0.3s;
}
.sparkle-button:active {
scale: 1;
transition: 0.3s;
}
Adding Sparkle Effect with SVG
The sparkle effect is achieved using SVG paths. Each sparkle is defined with specific properties for a unique look.

Animating the Sparkles
We will now animate the sparkles using CSS keyframes. This will give them a bouncing effect.
.sparkle path {
color: hsl(0 0% calc((var(--active, 0) * 70%) + var(--base)));
transform-box: fill-box;
transform-origin: center;
fill: currentColor;
stroke: currentColor;
animation-delay: calc((var(--transition) * 1.5) + (var(--delay) * 1s));
animation-duration: 0.6s;
transition: color var(--transition);
}
.sparkle-button:is(:hover, :focus-visible) path {
animation-name: bounce;
}
@keyframes bounce {
35%, 65% {
scale: var(--scale);
}
}
Integrating Background and Particle Effects
We’ll add a gradient background and particles that appear when the button is hovered or focused.
.sparkle-button:before {
content: "";
position: absolute;
inset: -0.2em;
z-index: -1;
border: 0.25em solid hsl(260 97% 50% / 0.5);
border-radius: 100px;
opacity: var(--active, 0);
transition: opacity var(--transition);
}
.spark {
position: absolute;
inset: 0;
border-radius: 100px;
rotate: 0deg;
overflow: hidden;
mask: linear-gradient(white, transparent 50%);
animation: flip calc(var(--spark) * 2) infinite steps(2, end);
}
@keyframes flip {
to {
rotate: 360deg;
}
}
Enhancing Button Interaction
Adding more interaction enhancements ensures the button responds fluidly to user actions like hover and focus.
.sparkle-button:is(:hover, :focus-visible) {
--active: 1;
--play-state: running;
}
Implementing Active State Styling
Styling the button’s active state involves subtle changes that make it feel responsive and lively.
.sparkle-button:active {
scale: 1;
transition: 0.3s;
}
Keyframes Animations
Defining keyframes animations for our sparkle paths to create dynamic movement.
@keyframes float-out {
to {
rotate: 360deg;
}
}
Optimizing for Performance
Ensuring the animations and effects don’t negatively impact performance is crucial. Use CSS properties and techniques that are optimized for modern browsers.
.sparkle path:nth-of-type(1) {
--scale: 0.5;
--delay: 0.1;
--base: 40%;
}
.sparkle path:nth-of-type(2) {
--scale: 1.5;
--delay: 0.2;
--base: 20%;
}
.sparkle path:nth-of-type(3) {
--scale: 2.5;
--delay: 0.35;
--base: 30%;
}
