Add More Right/Left Margins

Hi, I am using Newspaper as a 1-column theme.

I need to add more white space in the margins when the theme is responsive (for tablets, wide phones, and smartphones). Specially in my Right margin.

How can I add more Right/Left Margins when going responsive?

Hi, I’ve solved this by using the following CSS (in both standard Theme and Mobile Theme):

body {
margin-right: 30px;
background-color: white;
}
