Button styles, PULSE micro-interaction, and CTA best practices.

Button HTML

<!-- Primary: filled accent — most important CTA on page -->
<a href="#shop" class="btn-primary btn-accent">Start Performing</a>

<!-- Ghost: outline only — secondary action -->
<a href="#science" class="btn-ghost">See the Science</a>

<!-- Text link — lowest commitment -->
<a href="#ingredients" class="btn-text">Read the ingredients →</a>

<!-- Small variant — nav CTA -->
<a href="#shop" class="btn-primary btn-accent btn-sm">Shop Now</a>

CSS

/* Shared base */
.btn-primary, .btn-ghost, .btn-text {
  display: inline-flex;

  gap: 0.5rem;
  text-decoration: none;
  font-family: var(--font-body);
  font-weight: 600;
  font-size: 0.9375rem;  /* 15px */
  letter-spacing: 0.01em;
  border-radius: var(--radius);
  cursor: pointer;
  transition: box-shadow var(--dur-mid) var(--ease-out);
  white-space: nowrap;
  min-height: 48px;  /* Fitts's Law — minimum touch target */
  padding: 12px 28px;
}

/* Filled accent button */
.btn-accent {
  background: var(--accent);
  color: var(--dark);
  border: 2px solid transparent;
}

GSAP PULSE (from micro.js)

function initButtons() {
  // Primary CTA buttons
  document.querySelectorAll('.btn-primary').forEach(btn => {
    btn.addEventListener('mouseenter', () => {
      gsap.to(btn, { scale: 1.03, duration: 0.2, ease: 'back.out(1.7)' });
    });
    btn.addEventListener('mouseleave', () => {
      gsap.to(btn, { scale: 1, duration: 0.2, ease: 'power2.out' });
    });
    btn.addEventListener('mousedown', () => {
      gsap.to(btn, { scale: 0.97, duration: 0.08, ease: 'power3.in' });
    });
    btn.addEventListener('mouseup', () => {
      gsap.to(btn, { scale: 1.02, duration: 0.15, ease: 'back.out(2)' });
    });
  });
}

Microcopy Pattern

Always pair the primary CTA with risk-reduction microcopy directly below:

<div class="cta-group">
  <a href="#shop" class="btn-primary btn-accent">Start Performing</a>
  <p class="cta-microcopy">60-day guarantee · Free shipping over $50</p>
</div>
.cta-group {
  display: flex;
  flex-direction: column;
  align-items: flex-start;
  gap: 0.75rem;
}

.cta-microcopy {
  font-size: 0.8125rem;
  color: var(--gray);
  line-height: 1.4;
}

CTA Placement Rules

  • Hero — Primary CTA + ghost CTA + risk microcopy, above the fold
  • Post-proof — Repeat primary CTA immediately after testimonials (most visitors convert here)
  • Final CTA section — Primary CTA only; context is "decision time"
  • Nav — Small primary CTA in header (always visible on scroll)
  • Never — Two identical primary CTAs side by side (creates choice paralysis)

Focus State (accessibility)

.btn-primary:focus-visible,
.btn-ghost:focus-visible {
  outline: 2px solid var(--accent);
  outline-offset: 3px;
}
