List out the things that have to be done here.

Bugs to be fixed-:

1. Consistency in appending the first message that at times gets appended under the header margin.

2.Providing line break when a user enters holding the shift key i.e-- Shift+Enter=line break.

UI improvements-:
1.The header can be replaced with a menu bar of a good height as that might not interfere with the CSS
of the segment class(presently being used) and by default always stays at the top.

2.Different shades of the same color div for user messages and received messages.

3.Changing the width of the chat divs and that will be different for mobile,tablet and computer views.

Please review and suggest if any other changes needs to be included or if there are any correction in present suggestion list. @sumedh123 @kvnamipara @AdityaHirapara @jainkeval
