CSS cue-before
The CSS cue-before
property is used in speech media to play a sound before an element.
The cue-before
property allows you to play pre-recorded sound clips immediately before an element. These pre-generated clips are referred to as "auditory icons". Auditory icons can be a useful way to distinguish semantic elements.
Also see the cue-before
and cue
properties.
Syntax
Example Code
Possible Values
- uri
- This value specifies the URI of an auditory icon resource.
- decibel
-
This is a number followed by
dB
(decibel unit identifier).This value represents a change relative to the computed value of the
voice-volume
property. Therefore, the level of the audio cue changes when the level of thevoice-volume
property changes.When omitted, the implied value computes to
0dB
(i.e. no change). none
- Specifies that no auditory icon is used.
In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:
initial
- Represents the value specified as the property's initial value.
inherit
- Represents the computed value of the property on the element's parent.
unset
- This value acts as either
inherit
orinitial
, 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.
