Dottoro Theme provides pre-defined widget areas created to meet the most frequent needs.
By applying them you can put widgets onto your sidebar, footer and contents.
You can also create as many custom widget areas as you want so you can fully personalize your theme.
Inside a widget area you can define the layout of all of your widgets and you can set custom widget areas on the sidebars and footers of all pages which puts you in full charge of the appearance of your sidebars and footers.
In case you want to insert widget areas in your subheaders and content you will have to use the [widget_area] shortcode
Having the possibility to set all these options for yourself you can have page-dependent widgets in all regions of the page - the sidebar, footer, subheader and the content as well.
