check-box(key, value, ..., key, value)

Inserts a check box control in generated content. This control can be used to edit the value of the element which is the target of the CSS rule. If "attribute, attribute_name" is specified, this control can be used to edit the value of an attribute of this target element.

Key	Value	Default	Description
attribute	Qualified name of attribute to be edited	No default	Without this parameter, the control is used to edit the value of the element for which the control has been generated.
label	String	None	Label used for the check box.
unchecked-value	String	None	In normal mode, `unchecked-value` must be specified. Unchecking the control assigns this value to the attribute or element value being edited. See also remove value mode below.
checked-value	String	None	In normal mode, `checked-value` must be specified. Checking the control assigns this value to the attribute or element value being edited. See also remove value mode below.
allow-empty-checked-value	Boolean: yes\|no, 1\|0, "true"\|"false", "on"\|"off"	no	Consider the empty string (`""`) to be an alias for `checked-value` (which must have been specified). This parameter is used to implement XHTML5 form controls.
remove-value	Boolean: yes\|no, 1\|0, "true"\|"false", "on"\|"off"	no	Turns remove value mode on and off. In remove value mode, one but not both, of `unchecked-value` and `checked-value` must be specified: if `unchecked-value` is not specified, unchecking the control removes the attribute being edited. if `checked-value` is not specified, checking the control removes the attribute being edited. If the value being edited is an element value rather than an attribute, instead of removing the attribute, the value of the element is set to the empty string.

Key, value, ..., key, value may also specify style parameters.

Examples:

check-box(attribute, value,
          unchecked-value, "false", 
          checked-value, "true")

check-box(label, "Yes", 
          unchecked-value, "no", 
          checked-value, "yes")

check-box(attribute, value,
          label, "Disabled", 
          checked-value, "disabled",
          remove-value, yes)

check-box(label, "Hidden", 
          checked-value, "hidden",
          remove-value, yes)
