visual improvements

I changed some css stuff so it looks like more than the original duality page.

• removed boxshadows, added simple border instead
• removed the unnecessary spin animation in categories
• adjusted colors
• fixed footer margin

Nice, although I'd keep the spin animation, it looks visually appealing.

@Kliktrix I added a simple transition effect instead

Thank you! In my opinion, the header and footer definitely looks better, however I miss the background texture. Plain grey is just ... grey. I think we don't have to stick to the official page in this matter.

Is using bg textures very dated by today's standards? If yes, can we re-iterate on the color a bit?

1980's calling... they want their backgrounds back. Just kidding 😋 So should I put back the background-texture? If no, what color do you prefer?

I tried different backgrounds, but had the impression, that they only fit with the original shadowy boxes. Also, coloring the background didn't help. Let's stick with your version for now.
