CSS PAUSE-BEFORE

This property specifies a pause to be inserted before speaking an element’s content. The pause is inserted between the element’s content and any ‘cue-before’ or ‘cue-after’ content.

Example
1
blockquote { pause-before: 1.5s }
1
<blockquote style="pause-before: 1.5s">text</blockquote>

Possible Values

inherit: Explicitly sets the value of this property to that of the parent.
[time]: Sets the pause length to a time measurement (see the time units for more details)
[percentage]: Refers to the inverse of the value of the ‘speech-rate’ property. (eg: a value of 100% for ‘pause-before’ with a ‘speech-rate’ of 60 words per minute would create a pause of 1 second.)
