Yes! AdSanity ships with default styles in place this website. However, your theme’s styles will override AdSanity’s default styles. We do include general and specific handles on all the AdSanity elements so that custom styling can be used to alter the display of the ads to your specific needs. Ultimately your theme’s style will govern how AdSanity’s ads are displayed and whether or not those behaviors are responsive. To be able to show different content for different screen sizes, one could make use of media queries to hide show ads as necessary.
