Changed navdrop names, figures on 'model.html' with round borders, added 'index.html' pseudo-animation.

Fixed the timeline card fade-out/blur, changed the title banner to a translucent gradient, fixed the double 'contribution.html' link, added 'safety.html', started working on 'model.html'.

Loaded scrolled page with white background navbar, attempts on sidebar/home logo overlay failed so far.

Shortened the navbar, pushed the container div left, made the navbar interactive for mobile touch events.

Fixed the sidebar slide, improved the navbar dropdown menu shape, made dropdown menus show up only on hover.

Added 'improvement.html' to try and fix 'ValueError: Unexpected status '500 INTERNAL SERVER ERROR' on URL /improvement'.
