[Bug]: Transparent footer overlapping with sidebar content in docs

[Pranav-IIITM]

Prerequisites

• I searched existing issues and found no duplicates
• I can reproduce this issue consistently
• This is not a security vulnerability (use Security Advisories instead)

Bug Description

The footer on the documentation site (docs.nvidia.com/aicr) currently has a transparent background. Because of this, when scrolling to the bottom of a page, the footer text and links visually overlap with the left navigation sidebar. I expected the footer to have a solid background color so that it blocks out the content behind it, keeping the text readable.

Impact

Low (minor issue)

Component

Docs / examples

Regression?

Unknown / first time using this feature

Steps to Reproduce

1. Navigate to https://docs.nvidia.com/aicr/overview/introduction/ (or any docs page with short content).
2. Scroll to the absolute bottom of the page.
3. Look at the bottom-left corner of the screen where the footer intersects with the navigation sidebar.
4. Notice that the footer is transparent and overlaps the sidebar text.

Expected Behavior

The footer should have a solid background color (matching the current light/dark theme) so that it overlays cleanly above the sidebar, preventing any text from bleeding through.

Actual Behavior

The footer is completely transparent, making both the footer links and the sidebar text unreadable where they overlap.

Environment

Live documentation site (docs.nvidia.com/aicr) viewed on any modern web browser.

Command / Request Used

No response

Logs / Error Output

N/A (Visual CSS bug, see attached screenshot).

Additional Context

A similar issue was recently identified and fixed over in the NVIDIA/nvcf repository by me .(NVIDIA/nvcf#855)
The fix involved adding a background color and a z-index to footer.bd-footer (or #fern-footer) in the custom CSS configuration for Fern.
