responsive and quite good

What did you find difficult while building the project? =from my past challenges I thought this one to be tough and this is not that though but doing it the tough way makes it tough for me.

Which areas of your code are you unsure of? =i am happy with the code but I like some assistance

I need help -- whenever I put background image in CSS section it doesn't apply but in case I do it in HTML it gets applied and I do the same right way also the code works in the live server but not in local path copy paste to google chrome way ultimately CSS background-image code doesn't work but putting same in style in HTML works everywhere whyyyyy
