# Transitions in CSS

Now, let’s take a look at how to animate components using CSS transitions!

A **transition** occurs when we tell a CSS property value to change over a specified period of time.

We do this with the `transition` property, which is shorthand for the following properties:

- `transition-property`
- `transition-duration`
- `transition-timing-function`
- `transition-delay`

See how these properties look in the code snippet below:

```css
.element {
  transition-property: property;
  transition-duration: duration;
  transition-timing-function: timing-function;
  transition-delay: delay;
} 
```

The code above is equivalent to:

```css
.element {
  transition: property duration timing-function delay;
}
```

# Transition Properties

We use the following transition properties:
- The `transition-property` property defines the transition we want to apply.
- The `transition-duration` property defines transition’s duration. The value is specified in seconds (`5s` for 5 seconds).
- The `transition-timing-function` property defines how the transition occurs.
- The `transition-delay` property allows us to set a delay before the transition starts. - The value is also specified in seconds (`5s` for 5 seconds).

# Activating transitions

We can activate a CSS transition with pseudo-classes like `:hover` (moving a mouse over the element), `:focus` (clicking an input element), or `:active` (clicking the element).
