  ## Animating a simple transition
  -Let's animate a simple transition that changes a single HTML element from one state to another. For example, you can specify that a button displays either **Open** or **Closed** based on the user's last action. When the button is in the `open` state, it's visible and yellow. When it's the `closed` state, it's transparent and green.

  In HTML, these attributes are set using ordinary CSS styles such as color and opacity. In Angular, use the `style()` function to specify a set of CSS styles for use with animations. You can collect a set of styles in an animation state, and give the state a name, such as `open` or `closed`.
