6. What is the default value for tabindex attribute?
a) No default value
b) Any value greater than zero
c) One
d) zero
View Answer
Explanation: Elements that could gain focus but do not have a tabindex attribute are automatically given a value of 0. Therefore, when you specify a tabindex value, it should be 1 or higher, rather than 0.If an element is disabled, it cannot gain focus and does not participate in the tabbing order.
7. What happens if two elements have the same tabindex value?
a) They will not be navigated at all
b) They will be navigated simultaneously
c) They will be navigated in the order in which they appear in the document
d) It lets the user decide to navigate to which element
View Answer
Explanation: If two elements have the same value for a tabindex attribute, they will be navigated in the order in which they appear in the document. So, once the elements that have a tabindex of 1 or more have been cycled through, the browser will cycle through the remaining elements in the order in which they appear in the page.

b) The source code won’t display anything on executing/implementing
c) The post method will be used as default
