This CSS attribute can be used to specify the label used for a custom tag. If using this attribute with either block or inline tags then it should be used instead of the ephox-start-label and ephox-end-label attributes. When specifying an label to represent an empty tag this attribute must be used.

The following example specifies the label Custom Tag for the start and end tag labels of the custom tag MyTag.

MyTag{
  display: block;
  ephox-label: Custom Tag
}
