pause-before property is used in speech media to specify prosodic boundary (a pause) before an element.
pause-before property can help your listeners comprehend the content by allowing you to provide extra "space" before certain elements. For example, adding a slight pause before a main heading could help distinguish the heading from the previous content while also communicating the significance of the heading.
pause-before property can be seen as the speech media equivalent to the
margin-top property in visual media.
- Expresses the pause in absolute time units (for example
50ms). Only non-negative values are allowed.
- Equivalent to
0ms(no prosodic break is produced by the speech processor).
- These values express the pause by the strength of the prosodic break in speech output. The exact time will depend on the output device/user agent being used.
In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:
- Represents the value specified as the property's initial value.
- Represents the computed value of the property on the element's parent.
- This value acts as either
initial, depending on whether the property is inherited or not. In other words, it sets all properties to their parent value if they are inheritable or to their initial value if not inheritable.
- Initial Value
- Applies To
- All elements.
