@bharath-kondeti I see you have a change in compiled main.js file, but there is no source js change in PR.
Could you add it as well?
I want to ensure we are not losing your change once main.js recompiled next time without your change in source files

@podarok, I did not make any changes to any JS file. When I complied my css change there were changes in both styles.css and main.js as well. Hence, i have added those as a part of this PR.
