Hi LMKWeb,

There is a following break point for responsiveness

@media only screen and (max-width: 1078px) 
@media only screen and (max-width: 767px) 

In style.css line number 2012 there is

#primary, #secondary,
#colophon .widget {
	float: none;
	margin-left: 0;
	width: 100%;
}

remove line #primary, #secondary, which is a break point that makes column and sidebar 100% and you will see the same view as desktop view. If you want to break this 768px after paste below CSS code under this @media only screen and (max-width: 767px)

#primary, #secondary {
	float: none;
	margin-left: 0;
	width: 100%;
}

before editing core CSS file please consider about child theme. If you edit the core CSS file your changes will be lost when you update a theme.

Thank you!
