Yes. Our widgets are designed to respond to the size of the container in which they reside. If your site is responsive then our widgets will adjust their layout.
Should you need to modify the responsive layout, look for the following classes that get added to our v2 div based on the widget's parent container width.
"v2-xs" less than 599px width
"v2-sm" between 600px and 992px width
"v2-md" greater than 992px width
