[BUG] Footer renders in sequential layout instead of parallel columns on mobile

[ESHAYAY]

Description

On mobile viewports, the footer sections stack one after another in a single sequential column
instead of rendering side-by-side in a proper parallel/grid layout. This breaks the intended
multi-column footer structure and makes it look unfinished on small screens.

Steps to Reproduce

1. Open the site at codepvg.onrender.com
2. Open DevTools → Toggle device toolbar (or use a physical mobile device)
3. Set viewport to ~375px–414px width
4. Scroll to the footer — sections stack vertically in a single column

Expected Behavior

Footer sections should display in a responsive grid layout — side-by-side on wider mobile
viewports and stacking gracefully only on the narrowest screens. Something like:

@media (max-width: 768px) {
  .footer {
    display: grid;
    grid-template-columns: repeat(2, 1fr);
    gap: 1rem;
  }
}

Actual Behavior

All footer sections render sequentially in a single column, ignoring any parallel/grid layout.
