Imagine you have a DIV element in your document with the id "row". Now, if you add another DIV with the same id and change the display property of the first DIV to "none", does the id of the second DIV become unique?
Imagine you have a DIV element in your document with the id "row". Now, if you add another DIV with the same id and change the display property of the first DIV to "none", does the id of the second DIV become unique?
Incorrect. The CSS property Display:none simply hides the element from view without removing it from the DOM. This means the element still exists in your code and can be manipulated using JavaScript.
It is important to note that whether or not elements are hidden (display: "none") in the document, they are still present within the DOM. Additionally, even if these elements are dynamically created, it is crucial that they do not share the same ID as this violates valid markup standards.
