Monstrosity
A template that I made with CSS and HTML. It has a dark theme with red accents. It has a scrollbar and a GIF as background image, both of with you can see animated here: click.
the final result

the code
Of course, it doesn't just appear. I coded the style elements with CSS and then put it together in the right order with HTML. The code you can see below.
