It’s very important to understand the difference between a widget and a widget area. Please see the below information to help understand the difference between the two.
Widget – A WordPress Widget is a small block that performs a unique function. Avada includes several custom widgets such as the Avada Twitter widget, Avada Social Links, or the Avada Recent Work widget. In addition, there are several default widgets that WordPress includes such as Recent Posts or Recent Comments. Widgets can go inside a widget area, and as of Avada 6.2, can also be placed and edited directly on the page using the new Widget Element.
Widget Areas – A Widget Area is a container that holds widgets. Avada includes 2 pre-made widget areas (footer columns, sliding bar columns) and also allows you to create custom Widget Areas which can be applied to the 5 widget-ready areas of the theme. It’s a great way to customize your site.
