Template looks completly different on mobile

Hello everyone!

I’ve been using this theme over a year by now, did some changes and updates on my blog https://unblogchino.com/ but there’s always this thing that i don’t know how to change.

The template looks absolutely different (and awful) on mobile devices. I checked online and as responsive, my site should look like this https://s28.postimg.org/ldpqxrqkt/image.jpg, but it doesn’t. It looks plane, no social icons or header and BLUE https://s30.postimg.org/iibyrp881/Screenshot_2016_03_23_19_26_44.png

PS: i checked the site on several smartphones and it looks just as bad on every single one of them.

Does anyone has this same issue? How did you fixed it?

Thanks!
