Personally I am very fond of dark websites even though clean light web design is the main choice, especially in the corporate world. It is true that dark designs have a tendency to feel a bit heavy and harder to read if lot of text is presented but I feel they look more elegant and creative. Besides, using dark backgrounds you can make the content stand out and be the main focus.
So, without a second thought I decided to entertain and inspire you with this beautiful showcase of SharePoint-based dark websites.
Feel free to comment and let us know if you came across other creative dark websites built on SharePoint platform.
