The Timer Element

The ontimer attribute of the card element may be used with the timer element to automatically move to a new card after a predefined time. The ontimer attribute is assigned the name of the card to go to when the timer expires.

The timer element has a value attribute that determines how long to wait before the timer expires. The time is specified in 1/10ths of a second, therefore a value of ten will be approximately 1 second. Each card may only have a single timer element.

The following example has three cards. The first card has an ontimer event, set to expire after 3 seconds where it automatically moves to the next card. The next card also has an ontimer event that expires after 3 seconds to move automatically to the final card.
