initial
The initial CSS keyword applies the initial value of a property to an element. It is allowed on every CSS property and causes the element for which it is specified to use the initial value of the property.
Example
<!DOCTYPE html>
<html>
<head>
<style>
/* make second-level headers green */
/* give headers a green border */
h2 {
border: medium solid green
}
/* but make those in the sidebar use the value
of the "color" property */
#sidebar h2 {
border-color: initial;
}
</style>
</head>
<body>
<p style="color:red">
this text is red<em style="color:initial">
this text is in the initial color (e.g. black)
</em>
this is red again
</p>
</body>
</html>
