Logo expands to hide book title in sidebar

[joelostblom]

Describe the bug

context When I create a book using this minimal _config.yml, the logo shows up as bigger than expected and covers the title in the side bar.

title: My sample book
author: The Jupyter Book Community
logo: logo.png
only_build_toc_files: true
execute:
  execute_notebooks: force

expectation I expected the logo to show up above the title and not cover it

bug Instead of the desired behavior:

I now see this:

No error shows up when building, but a few seemingly unrelated warnings:

The HTML pages are in _build/html.

problem This is a problem because it is helpful to have the title of the page in the side bar and the giant logo does not look very appealing.

Reproduce the bug

I tried this with a completely new book as well and same results:

jupyter-book create mybook
jupyter-book build mybook
