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 inherit or 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.
Depends on the value of the individual properties (i.e. pause-after and pause-before). Their initial value is none.
