CSS selectors

I can’t seem to get my css selectors to show up when I edit font controls. Here’s what I’ve done: used the find button in my css stylesheet to find my current font (lobster two), everywhere it shows up I take that css and add it to the plugin editor, but nothing is happening after I hit save. (I’m inputing .site-title, .title-area etc.) http://www.somedayatatime.com. Thanks for any help!
