How does the GSAP timeline animation work for the truck sequence?

A GSAP timeline (gsap.timeline()) chains all animation stages. gsap.set resets the truck position before each click. tl.to moves the truck left:-120 to left:110 with power2.inOut. The suspension bounce uses tl.to with y:-7, rotationZ:-1 then y:0, rotationZ:0 with bounce.out ease. Door opening uses tl.to with rotationY:-115 at power2.inOut. The package drops with rotation:720 and bounce.out. tl.call() runs helper functions at precise moments. The position string '-=0.35' creates overlapping stages for cinematic timing.

How does the package detach from the truck and stay on the button?

The package (.box) is initially a child of #truck, positioned within the truck's coordinate space. In tl.call(), JavaScript uses getBoundingClientRect() to get the package's current screen position, then appends it to the button element (btn.appendChild(box)). gsap.set repositions it using the difference between the package's screen coordinates and the button's coordinates: x = bx.left - b.left, y = bx.top - b.top. This seamlessly transfers the package from the truck's coordinate system to the button's, so it visually stays in place while the truck exits.

🎬 All 6 Stages — Technical Reference

Every GSAP call, CSS technique, and JavaScript function behind each cinematic stage.

① GSAP + CSS

Entry + Road

GSAP moves truck left:-120 to left:110 using power2.inOut over 1.6s. Road .road-mini uses repeating-linear-gradient with @keyframes roadMove shifting background-position by 39px (one pattern width). JavaScript adds class .moving to toggle animation-play-state from paused to running.

tl.to(truck, {left:110, duration:1.6, ease:'power2.inOut'});
road.classList.add('moving');
/* CSS: .moving .road-mini { animation-play-state: running } */

② GSAP ease

Suspension Bounce

Two tl.to calls create the bounce. First: y:-7, rotationZ:-1 with power2.out at 0.22s — the overshoot up. Second: y:0, rotationZ:0 with bounce.out at 0.28s — the settle. Five exhaust .exhaust divs are created in a loop with staggered gsap.set and gsap.to calls scaling up and fading out.

tl.to(truck, {y:-7, rotationZ:-1, duration:0.22, ease:'power2.out'});
tl.to(truck, {y:0, rotationZ:0, duration:0.28, ease:'bounce.out'});

③ GSAP rotationY

Door Open + Sparks

GSAP animates .truck-door to rotationY:-115deg over 0.75s with power2.inOut. The door's transform-origin: left center makes it hinge from the left edge. createSparks helper fires 6 spark divs using CSS --dx/--dy custom properties calculated from Math.random() * 360 angle and 12–30px distance.

tl.to(door, {rotationY:-115, duration:0.75,
ease:'power2.inOut',
onStart: () => createSparks(door.getBoundingClientRect(), btn)});

④ GSAP bounce

Package Drop

Box opacity is set to 1 with tl.set. GSAP animates top from 12 to 34 with rotation:720 (two full spins) and bounce.out over 0.6s, simulating gravity and impact. Impact sparks fire on onStart. Dust particles called with tl.call. The FRAGILE text label uses 3.2px font with diagonal rotation.

tl.set(box, {opacity: 1});
tl.to(box, {top:34, rotation:720,
duration:0.6, ease:'bounce.out',
onStart: () => createSparks(box.getBoundingClientRect(), btn)});

⑤ JavaScript

Package Detach

In tl.call, getBoundingClientRect gets the box's current screen position. btn.appendChild(box) moves it from truck's DOM to button's DOM. gsap.set repositions it using coordinate difference: x = bx.left - b.left, y = bx.top - b.top. This seamlessly transfers coordinate spaces while the box visually stays in place as the truck exits.

const bx = box.getBoundingClientRect();
const b = btn.getBoundingClientRect();
btn.appendChild(box);
gsap.set(box, {x: bx.left-b.left, y: bx.top-b.top, left:'auto', top:'auto'});

⑥ GSAP exit

Exit + Reset

Truck drives to left:370 (off right edge) with power1.inOut over 1.5s. Button scale resets to 1 with power2.out. In timeline onComplete: btn.disabled = false, text.style.opacity = 1, road.classList.remove('moving') to pause the road. gsap.set resets all positions for the next click.

tl.to(truck, {left:370, duration:1.5, ease:'power1.inOut'});
/* onComplete: btn.disabled=false; road.classList.remove('moving'); */

CINEMATIC TRUCK FAQ

How the CSS truck, GSAP timeline, road animation, package detach, and sparks work.

How is the CSS delivery truck built without images?

The truck is entirely HTML divs with CSS styling. The red cab uses linear-gradient with perspective(250px) rotateY(-7deg) for the 3D angle. The windshield is a ::before pseudo-element with a blue gradient. The cargo body uses a blue gradient with perspective. Wheels use radial-gradient for the rubber look and repeating-conic-gradient with a radial mask for tread. Headlights use radial-gradient(#fff, #ffeb3b, #ffb300) with glowing box-shadow. The FRAGILE box uses diagonal repeating-linear-gradient for wood grain. Zero images, zero SVG — pure CSS.

How does the GSAP timeline animation work for the full truck sequence?

A GSAP timeline chains every stage. gsap.set resets positions before each click. tl.to moves the truck with power2.inOut. Position strings like '-=0.35' create overlap between stages for cinematic timing. The suspension uses two tl.to calls: y:-7 with power2.out (overshoot up) then y:0 with bounce.out (settle). Door uses rotationY:-115. Package uses rotation:720 and bounce.out. tl.call() runs JavaScript at exact timeline moments. The timeline's onComplete resets the button.

How does the animated road inside the button work?

The .road-mini uses repeating-linear-gradient to draw asphalt with yellow dash markings at 39px intervals. @keyframes roadMove shifts background-position from 0 to 39px, creating the scrolling road illusion. The animation starts in paused state via animation: roadMove 0.45s linear infinite paused. JavaScript adds the .moving class on click, which sets animation-play-state: running via the CSS selector .moving .road-mini. The wheel spin @keyframes also activates via .moving .truck-wheel. On timeline completion, .moving is removed.

How does the package detach from the truck and stay in place?

In tl.call, three steps happen: (1) btn.appendChild(box) moves the .box element from the truck's DOM to the button's DOM. (2) getBoundingClientRect() captures the box's screen position before and after the parent change. (3) gsap.set repositions it using the coordinate difference: x = bx.left - b.left, y = bx.top - b.top, with left and top set to 'auto'. This transfers the element between coordinate systems while maintaining its exact visual position, so the box stays where it landed while the truck drives away.

How are the sparks created in JavaScript?

createSparks creates 6 .spark divs. Each gets CSS custom properties --dx and --dy from a random angle (Math.random() * 360) and distance (12–30px): Math.cos(angle)*distance and Math.sin(angle)*distance. The spark is positioned at the source element's center relative to the container using getBoundingClientRect. The CSS @keyframes spark uses transform: translate(var(--dx), var(--dy)) scale(0) to move each spark in its unique direction while shrinking to nothing. setTimeout removes each after 700ms.

Can this truck button be used for e-commerce?

Yes. It works perfectly for add-to-cart confirmations, shipping notifications, order tracking, and delivery confirmation CTAs. Replace 'DELIVER PACKAGE' with 'Add to Cart' or 'Place Order'. Add your checkout API call inside the tl.onComplete callback after btn.disabled = false. The button automatically disables during animation to prevent double-clicks. Consider reducing timeline durations by 30–40% for a snappier e-commerce feel. The frosted glass button style matches premium dark-themed storefronts.
