Hello, I need some help with css.

This is my current css for my wiki. I am trying to add this image next to my name in chat.

However, the size is not affected, and instead of showing the full image next to my name it comes out as this, these small red lines. I was wondering how to get the full image next to my name, scaled to the size I specified in the background-size tag, which did not work.
