† The dagger symbol (†) indicates that
the feature only applies when the multiple
attribute is not
specified.
The value
content attribute gives the default value of the input
element.
The checked
content attribute is a boolean attribute that gives the
default checkedness of the
input
element.
The form
attribute is used to
explicitly associate the input
element with its
form owner. The name
attribute represents the element's name. The disabled
attribute is used to make
the control non-interactive and to prevent its value from being
submitted. The autofocus
attribute controls focus.
