Center footer for "Edit this page" not horizontally aligned on narrow screens

I have:

• searched the issue tracker for similar issues
• installed the latest version of Quarto CLI
• formatted my issue following the Bug Reports guide

Bug description

When adding "Edit this page" to the website with repo-actions and repo-url in _quarto.yml, the center footer is not horizontally centered when viewing on narrow screens. A screenshot is attached.

A look at the CSS styles in the browser show that a padding-left: 2rem is being added to the relevant <ul> tag. Removing/overriding this padding fixes the alignment.

Steps to reproduce

A minimal _quarto.yml to reproduce the issue.

project:
  type: website

website:
  title: "minimal-site"
  repo-url: "https://github.com/datascijedi/website"
  navbar:
    left:
      - href: index.qmd
        text: Home
      - about.qmd
  page-navigation: true
  repo-actions: [edit]
  page-footer:
    left: "© 2025 My Name"
    right: "Powered by Quarto"

format:
  html:
    theme:
      - cosmo
      - brand
    css: styles.css
    toc: true

Actual behavior

The footer center "Edit this page" is shifted slightly to the right on narrow screens.

Expected behavior

The footer center "Edit this page" should be horizontally centered including on narrow screens.

Reproduce the issue with the minimal _quarto.yml configuration and inspect the generated website footer on a narrow screen. Start with the footer's relevant

styles, especially the added padding-left: 2rem; done means the “Edit this page” footer action is horizontally centered without affecting the other footer content.
