Responsive Black Skyline

I’m not having any trouble except in trying to make this theme responsive. I’m a front-end web designer just learning WordPress.

I tried many suggestions on how to add code to the style.css to change the side when viewing from a smartphone, but nothing is working.

My employer loves this theme but wants it to be responsive and that’s where I am today. I have not found a theme that works so well with the header, text, widgets, etc. I would hate to move to another theme.

Any suggestions or is there a theme you have to match this one that is responsive?

Thanks,

Helen
