Definition and Usage
The readonly attribute is a boolean attribute.
When present, it specifies that a text area should be read-only.
In a read-only text area, the content cannot be changed, but a user can tab to it, highlight it and copy content from it.
The readonly attribute can be set to keep a user from using a text area until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript is required to remove the readonly value, and make the text area editable.
