There are some merge conflicts because I changed the directory structure of my fork.

Thanks @snehasi !

1. Merge conflicts do not arise from changing folder structures; something else must have happened. You should be able to resolve the merge conflict in your fork and push the changes to update the pull request.

2. Please remove binary files, such as .DS_Store

3. The page is more complex than before and with the monotone color scheme it becomes difficult to keep track of navigating the page. Could you introduce symbols, stock photos, and colors? It does not have to use all colors in the rainbow, just one or two accent and background colors would be great.
