initial - CSS（层叠样式表） 编辑

initial CSS关键字将属性的初始（或默认）值应用于元素。不应将初始值与浏览器样式表指定的值混淆。它可以应用于任何CSS属性。这包括CSS简写all，initial 可用于将所有CSS属性恢复到其初始状态。

注意：在继承的属性上，初始值可能是意外的。你应该考虑使用 inherit, unset，或revert 关键字代替。

示例

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;
}

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