CSS pause-after property

This property specifies a pause to be observed after speaking an element's content. The possible values are −

• time − Expresses the pause in absolute time units (seconds and milliseconds).
• percentage − Refers to the inverse of the value of the speech-rateproperty. For example, if the speech-rate is 120 words per minute (i.e. a word takes half a second, or 500ms), then a pause-after of 100% means a pause of 500 ms and a pause-after of 20% means 100ms.
