Bug: Visible default browser scrollbar affecting site aesthetics

[ParthAggarwal16]

Description

The default browser scrollbar is currently visible on the OpenCRE website, which creates a visual inconsistency with the site’s design. Previously, the scrollbar appeared to blend with the page background, but recent changes seem to have caused the browser’s default scrollbar styling to appear again.

Steps to Reproduce

1. Visit https://opencre.org/
2. Observe the scrollbar on the right side of the page
3. The scrollbar appears with the browser’s default styling instead of blending with the site’s background

Expected Behavior

The scrollbar should visually blend with the website background (or be styled consistently with the site’s theme), avoiding the default browser appearance.

Working on this issue and will open PR shortly for this
