I am proud of successfully completing this challenge.But I realize that it had taken me more time than it actually need. In the next time , I will try to do it in proper time.

What challenges did you encounter, and how did you overcome them?

I didn't read the style file and for this i am facing challenges to set the background color of body. But then I found it and this in way I managed to set the proper background color.

What specific areas of your project would you like help with?

Honestly I think I have done this project very well but still I think I need improvement in the spacing of elements like margin and padding.
