Goran's layout adjusts itself depending on the device you are using. This means your site will look good not only on laptop browsers, but also on devices with smaller screens, such as the iPad and the iPhone.
These are text widgets. The Text Widget allows you to add text or HTML to your sidebar. You can use a text widget to display text, links, images, HTML, or a combination of these. Edit them in the Widget section of the Customizer.
