/*
================================================================================================
style.css - Main stylesheet for the portfolio website.
------------------------------------------------------------------------------------------------
This file provides all the styling for the portfolio, following a modern, dark-theme design 
with orange accents, inspired by the Behance design.

Key features:
- Dark Theme: Uses a dark background (#121212) and light text for a comfortable viewing experience.
- Responsive Design: Uses media queries to adapt the layout for smaller screens (e.g., mobile phones).
- Interactive Elements: Includes styles for hover effects, animations, and a "back to top" button.
- Consistent Color Scheme: Uses a defined color palette with a primary orange accent.
