:read-only
Matches form control elements that have the |readonly
<http://www.whatwg.org/specs/web-forms/current-work/#readonly>|
attribute set, and to which the |readonly
<http://www.whatwg.org/specs/web-forms/current-work/#readonly>|
attribute applies (thus radio buttons will never match this,
regardless of the value of the attribute), as well as elements
defined by this specification that are not form controls (namely
|form|, |label|, |datalist
<http://www.whatwg.org/specs/web-forms/current-work/#datalist>|,
|option|, |optgroup|, and |fieldset| elements).
:read-write
Matches form control elements that do not have the |readonly
<http://www.whatwg.org/specs/web-forms/current-work/#readonly>|
attribute set (including |password
<http://www.whatwg.org/specs/web-forms/current-work/#password>|
controls, although technically they should be called "writeonly"),
or to which the attribute doesn't apply (such as radio buttons). A
disabled control can still match this pseudo-class; the states are
orthogonal.
I believe the term "orthogonal" is incorrect here. Following (the rest
of) the text, it occurs to me these pseusoclasses are opposite (mutually
exclusive), while orthogonal means, they can both apply, independent of
eachother.
Proposal: exchange "orthogonal" with "mutually exclusive", unless I
completely misunderstood
