Parallaxis has 12 extra content areas. Add content to these areas using the snippet below at the sidebar, body (access the body at page inspector > HTML Code > Body) or using the dedicated EC stacks element.
<div id="myExtraContent1"> Add your extra content here. </div>
You can also use the Global Code, if you wish to have the same content on all pages of your project. Access the Global Code at RapidWeaver Settings > Global Code.
Note that examples of all Extra Content areas are included in the package.
