Overview Description

The coala header in https://docs.coala.io/en/latest/ gets scaled only horizontally when viewed using mobile browsers leading to a distortion of the logo. It would be better if the consistency of the logo is maintained, else the koala bear starts looking like a starved chipmunk 😄

Steps to Reproduce

1. Open https://docs.coala.io/en/latest/ in any mobile web browser (portrait mode)

Actual Results

Expected Results

If the image scales while preserving aspect ratio and is aligned to the center or to the left, the logo would remain round.
