1- Place the element on the page.
2- Choose the "target date" you want, which is the date when the countdown ends.

3- Configure the properties according to your needs (some of these properties are for displaying the "Time remaining" from the element).

4.1-  Display the "Time remaining" directly from the element if you want to show a text countdown.

4.2- If you prefer to handle the display yourself, use the "Seconds remaining" property (which gives the remaining time in seconds).

5- When countdown is over, the element triggered the event "Time is up!"

Enjoy it !
