HTML | readonly Attribute
It is a Boolean attribute that is used to specify that the text written in input or text area Element is read-only. It means that a user can not modify or changes a content already present in a particular Element (However, a user can tab to it, highlight it, and copy the text from it). Whereas a JavaScript can be used to change the read-only value and make the input field editable.
