CSS Transitions

ELI5 — The Vibe Check

CSS transitions are the smooth operators of web design. Instead of a button color changing instantly on hover like a light switch, transitions make it gliiide smoothly from one state to another. Everything looks 10x more polished with zero effort.

Real Talk

CSS transitions animate property changes between two states over a specified duration. They're triggered by state changes like or class toggles. Transitions support timing functions (ease, linear, cubic-bezier) and can animate multiple properties simultaneously.

.btn {
  background: blue;
  transition: background 0.3s ease, transform 0.2s ease;
}
.btn:hover {
  background: darkblue;
  transform: scale(1.05);
}
