/*
    hdr-ftr.css
    Styles for the navigation bar and footer.
    
    OPTIMIZATION NOTES:
    - Ensured smooth transition for fixed/scrolled header using transform.
    - **FIXED: Offcanvas background color on all mobile/tablet resolutions (<= 992px) to prevent content overlap.**
    - Improved footer responsiveness and ensured all text aligns left.
