CSS speak-header

The CSS speak-header property is used in aural media to specify whether table headers are spoken before each cell, or only before each cell if that cell uses a different header to the previous cell.

In HTML5, header information can be specified with two different attributes (headers and scope). See the <th> tag for more information.

HTML 4 also had the axis attribute, but this has been removed from HTML5. See the HTML 4 <th> tag for more information.

Syntax

Possible Values

once
The header is spoken one time, before a series of cells.
always
The header is spoken before every pertinent cell.

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 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.
