CSS only working while in editor

Site URL: https://www.hanfordarc.squarespace.com

I know this issue has been discussed before and every solution seems to do with improper code. I am a CSS novice, so I am hoping there is a simple fix.  The issue, is, all my CSS works great while editing it, but after I save and navigate to the page it doesn't display any of the css.  All help would be greatly appreciated.

Thanks.
