Update landing page

[Jeremy-Walton]

Task

#117

Why?

The current landing page works pretty well, but it is not very clean.

I didn't change all that much, just added background, cleaned up the styles and added the airplane.

I wasn't able to get the testimonials put in place, but there is space under the download links for that in the future.

What Changed

• Update layout
• Remove unused style

Hey, I really like the gif in the background however I think a lot of things have been lost in the redesign process :

• The old layout was clear : Quick explanation -> Demo -> Download link where as this one is a bit messy I think. The download links and demo are way more important than the contributor list, the explanation shouldn't be in the top right corner but in page's content.
• The contributor list needs more padding I think
• I'm not really convinced by the white boxes/cards around elements
