Custom CSS

Hello,

I would like to add a bit of custom css to the template. I have Jetpack to use for custom css, but your theme loads the css after the Jetpack css loads causing it to overwrite anything I have done. I went into the css file to try and change it using the editor, but this theme does not seem to have a css file, just 2 import links. I cannot figure out how to change any of the css for this theme. Please let me know how I can edit the css. My site is http://www.spiralbridgestudios.com.
