The initial CSS keyword applies the initial (or default) value of a property to an element. The inital value should not be confused with the value specified by the browser's style sheet. It can be applied to any CSS property. This includes the CSS shorthand all, with which initial can be used to restore all CSS properties to their initial state.

Note: On inherited properties, the initial value may be unexpected. You should consider using the inherit, unset, or revert keywords instead.

Example

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;
}
