Site logo is stuck at top left of screen instead of appearing centered

[robin24]

Using Hugo and the Ananke theme, I've created a simple landing page.
I have specified a site_logo in SVG format in the config.toml file.
The logo is being used as expected and the site looks great on my iPhone, with the logo nicely centered above the website's text.
On my Mac, however, the logo appears to be stuck to the top left corner of the screen, tested with both Safari and Chrome.
Not sure if this is a bug that I'm encountering as my experience with CSS is sadly very limited. Thus, I'd like to know if this is expected behavior and if so, whether there's anything I could do to move the logo more towards the center of the screen, without altering the mobile appearance of the page?
