Browser screenshots:

When the page is loaded:

Jane Martin X + + → X O File C:/Users/neerakum/Desktop/roman.html O Ó G This page says Enter a number from 1 through 10 OK Ca

When the input is 9 and we click OK:

Jane Martin x + éane MartX local or shared the ® File C:/Users/neerakum/Desktop/roman.html ) 0 0 G This page says Enter a num

x + Jane Martin → C o + O File C:/Users/neerakum/Desktop/roman.html o O G This page says 9 as a Roman numeral is IX OK
