            Bug ID: 107644
           Summary: [13 Regression] Sphinx generated web pages is not
                    using the full width of the window
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED

screen shot of my chrome window

I have an ultra wide screen so I can read left to right without scrolling.
With the current way sphinx generated web pages are, they are centered in the
window even and just fill up part a small part of the window rather than the
full left to right.

If we can disable this centering and forcing only part of the window to be use
that would be great.
