CSS Styling

Core Concepts

• Specificity, cascade, and inheritance
• Box model: content + padding + border + margin
• Responsive units: rem, vw, %, clamp()

.card {
  padding: 1.25rem;
  border: 1px solid rgba(255,255,255,0.1);
  border-radius: 12px;
}

Flexbox

.row {
  display: flex;
  gap: 1rem;
  justify-content: space-between;
  align-items: center;
}

CSS Grid

.grid {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(240px, 1fr));
  gap: 1rem;
}

Transitions & Animations

.btn {
  transition: transform .2s ease, box-shadow .2s ease;
}
.btn:hover {
  transform: translateY(-2px);
  box-shadow: 0 10px 30px rgba(59,130,246,.4);
}
