What are sidebars & widgets?
The sidebar of the Meerkat theme is located on the right hand side of the page (shown tinted in red). Widgets are units of content inside of a sidebar (shown tinted in purple). By default, the content of a site’s sidebar is the same on every page of the site.
The homepage widget area, like a sidebar, can hold widgets. However, it appears in only one place- at the top of the front page of your site.
