as-countdown

For each of these a label is displayed. The labels default to Days, Hours, Minutes and Seconds. All customizations can be found here.

Styling

The component does not make any assumptions about stylings and displays the countdown as an inline element. You are free to style it in every way you want. Use these css selectors to apply styles accordingly:

as-countdown { /* root */ }
as-countdown > section { /* sections (days, hours, minutes, seconds) */ }
as-countdown > section > div { /* value for respective section */ }
as-countdown > section > label { /* label for respective section */ }

The done event

When the countdown has finished a done event is being dispatched. You can react to it like this:

const countdownEl = document.querySelector('as-countdown');

countdownEl.addEventListener('done', () => {
  /* Do whatever needs to be done */
});

If you use a JS framework you can use that framework's default event binding syntax. Here's an example for Angular:

<as-countdown
  date="2019-12-24"
  (done)="decorateChristmasTree()">
</as-countdown>

Behaviour

Fallback behaviour: Component shows 0 Days, 0 Hours, 0 Minutes and 0 Seconds.

• The date can be passed in as a timestamp or ISO string. Invalid dates will trigger the fallback behaviour
• Dates in the past will trigger the fallback behaviour
