HTML

<p>
  <span>This text is red.</span>
  <em>This text is in the initial color (typically black).</em>
  <span>This is red again.</span>
</p>

CSS

p {
  color: red;
}

em {
  color: initial;
}

With the initial keyword in this example, color value on the em element is restored to the initial value of color, as defined in the specification.

• Use the inherit keyword to make an element's property the same as its parent.
• Use the revert keyword to reset a property to the value established by the user-agent stylesheet (or by user styles, if any exist).
• Use the revert-layer keyword to reset a property to the value established in a previous cascade layer.
• Use the unset keyword to set a property to its inherited value if it inherits or to its initial value if not.
• The all property lets you reset all properties to their initial, inherited, reverted, or unset state at once.
