Homepage elements misaligned, wrong size

I haven’t made any changes to the site for a while, and it seemed to be working and appearing just fine, but recently, the homepage elements have suddenly become misaligned and minimized on the page.

Even the admin login screen and the dashboard appear distorted and small, and it’s impossible to get anything done in the admin interface.

Any clues on what might be going on and how I can fix this?

I would really like to get this fixed ASAP and would appreciate any feedback or advice.

Thank you!

RESOLVED: Seemed to be a browser resizing issue on my part. Hitting Cmd+0 did the trick.
