in my responsive.css @media screen and (min-width: 660px) after putting in what you have in nav my links disappear.

Hi Peter!

Thanks for writing back 9 days ago!

I was going to try and help before I read about your success!

The Treehouse Community is AWESOME!! :)

Make sure that you are viewing it between the media query's min-width and the next media query's (to do this you can either physically re-size your browser or simulate it in the Development Tools found in Google Chrome as well as many other browsers, but Google Chrome is simple to use and extremely customizable) as for each media query level the browser goes up, the browser will override the corresponding elements' CSS or style properties assuming you are not running into a cross-browser compatibility issue. The way to check that is ensure you are using the latest full version available since beta versions can have extra bugs and glitches, then try viewing it in another like Google Chrome, Internet Explorer, and Safari. In short, media queries are based upon view-size not simply screen resolution alone as otherwise the space may be too crammed even though it is all in High-Def resolution. If you need extra assistance I recommend either linking your code so we can check the rest of it as media queries make reverse cascading changes under best practices as you increase not desend like a cascading waterfall or as in the head of your HTML file; else, I would direct you to google to locate one of the top listed CSS validators and check your code there first as Treehouse teacher Nick Pettit always encourages, because it will be able to tell you if you have an orphin element or syntax error or perhaps need further more guided guidance.

i found out what i did wrong.. thanks guys! :)
