📚 Description

The new docs (#2310) have a gradient on the home page which is positioned absolute and overflows to the right of the page, as it takes 100% width.

(Checked with Firefox 117.0.1 and Chromium 116.0.5845.187 on Linux)

Possible changes are

  -> gradient shifted slightly right
• or to add a left: 0 to the absolutely positioned element
  -> gradient centered

I decided to use left: 0 which looks like this:
