Is it possible to use an input value attribute as a CSS selector?

Question

Is it possible to use a CSS selector to target an input that has a specific value?

Example: How can I target the input below based on the value=\"United States

Answer 1

Yes, but note: since the attribute selector (of course) targets the element's attribute, not the DOM node's value property (elem.value), it will not update while the form field is being updated.

Otherwise (with some trickery) I think it could have been used to make a CSS-only substitute for the "placeholder" attribute/functionality. Maybe that's what the OP was after? :)
