Size and placement of sidebar elements

[thriveth]

Hello, and thanks for making this theme available!

I am playing around with making a personal website using it, and have run into this problem that the sidebar elements seem off. I am using the latest Hugo-extended binary download.

I have attached a screenshot for illustration, showing the page in Chromium, but I get the same result in Firefox or Chrome. The logo image is placed too far up in the sidebar, cutting it halfway off, and if I try to zoom out, the text in the main area becomes a little on the small side.
