CSS Button & Hover Effects Generator
A button isn't done until you know what it does when someone's mouse actually touches it. This preview uses real CSS :hover and :active rules — go hover the button below for real, don't just imagine it.
Why a button generator needs a real hover state
A button's resting appearance is only half the design — the lift, glow, and brightness change on :hover, plus how it compresses on :active, are what make an interface feel responsive. Those states only exist in the browser's real interaction model, which is why this preview is a genuine button with genuine :hover/:active CSS rules instead of a static image.
Glass is one style among several here
The Glass preset borrows the same frosted-panel technique as the dedicated glassmorphism generator, but this tool is really about the interaction layer on top of any button style — solid, gradient, or outline get the exact same hover/press treatment.
Worked example: a button with lift, scale, and glow
With the default hover lift of 3px, scale of 103%, glow of 18, brightness of 110%, and a 0.2s transition, the generator writes:
.btn-generated {
background: #7c5cf0;
color: #fff;
border: none;
padding: 12px 24px;
font-size: 15px;
font-weight: 600;
border-radius: 10px;
cursor: pointer;
transition: transform 0.2s ease, box-shadow 0.2s ease, filter 0.2s ease;
}
.btn-generated:hover {
transform: translateY(-3px) scale(1.03);
filter: brightness(1.1);
box-shadow: 0 9px 18px rgba(124, 92, 240, 0.55);
}
.btn-generated:active {
transform: translateY(0) scale(0.97);
filter: brightness(0.95);
}
The resting state is a plain filled button. On hover it moves up 3px, grows to 103%, brightens by 10%, and gains a 18px glow in the button's colour. On press it drops back to its resting position and shrinks to 97%, which gives a tactile click. The transition line is what animates between those states, and it only lists the three properties that change, which is cheaper than transition: all.
Two additions are worth making before shipping a button like this. Keyboard users never trigger :hover, so add a visible focus style. And respect people who've asked their system to reduce motion:
.btn-generated:focus-visible {
outline: 2px solid #fff;
outline-offset: 3px;
}
@media (prefers-reduced-motion: reduce) {
.btn-generated { transition: none; }
.btn-generated:hover { transform: none; }
}
What changes in each state
| State | Default output |
|---|---|
| Resting | Filled background, 12px 24px padding, 10px radius |
:hover | translateY(-3px) scale(1.03), brightness 1.1, glow shadow |
:active | translateY(0) scale(0.97), brightness 0.95 |
:focus-visible | Not generated. Add the outline from the snippet above. |
Frequently asked questions
Why does my button's hover effect feel laggy or janky?
Animating properties like width, height, or box-shadow's spread directly forces the browser to recalculate layout on every frame. Animating transform (scale, translate) and opacity instead runs on the GPU and stays smooth even on lower-end devices.
Should hover effects work on mobile at all?
Touch devices don't have real hover state, so a hover-only effect simply never triggers there. It's worth also styling :active for touch feedback, since that's the closest equivalent to a mouse hover on a touchscreen.
What's a reasonable transition duration for a button?
Most interface motion feels responsive between 150-250ms. Much faster can feel abrupt or get missed entirely; much slower starts to feel sluggish and makes the interface feel like it's lagging behind the click.
Do hover effects need a reduced-motion fallback?
For subtle scale or color transitions, generally no — but larger movements (bounces, big transforms) are worth gating behind a prefers-reduced-motion media query so visitors with motion sensitivity aren't shown the full animation.
