rest-before property

Browser support:

Specifies that the browser should insert a rest before speaking the element's content.

With the rest-before and rest-after properties you can specify pauses before and after speaking the element's content.

The rest, rest-before and rest-after properties are similar to the pause, pause-before and pause-after properties. The only difference when a sound file needs to play before or after the element (cue, cue-before and cue-after properties). In that case, the pause-before property specifies the pause immediately before and the rest-before property specifies the pause immediately after playing the sound file that belongs to the cue-before property. Similarly, the rest-after property specifies the pause immediately before and the pause-after property specifies the pause immediately after playing the sound file that belongs to the cue-after property.

Note: Unfortunately, the pause-before and rest-after properties currently do not work for sound files in Opera, and the pause, pause-before, pause-after and rest, rest-before, rest-after properties have some other bugs (do not work for several valid time values).

JavaScript page for this property: restBefore. You can find other example(s) there.

Possible values:

One of the following values:

inherit

Takes the value of this property from the computed style of the parent element.

time(s|ms)

Integer, followed by a time unit (s,ms). The rest in absolute time.

Default: 0.
