Reply To: Question on responsiveness and padding entry-content

Unfortunetaly, I have a local site installation. It’s taking place on all the pages entry-content area.
The default is .entry-content {
padding: 0 20px 20px;
}
I want to include more space between the left and right content area. I included 7rem as margin-right and margin-left, but this is not displaying correctly on small devices.
