Widgets are elements outside the main content area of a web page that users can easily add, delete, and move around. A Widget might produce a list of all your blog categories; another might be a text box where you can update all your contact information; and yet another could contain the coding your mailing list manager provides for inserting a sign-up form.

Some Widgets come with WordPress, some are created by your theme, and still others appear when you install a plugin. There are literally thousands of possible free Widgets available through the Plugin Directory at WordPress.org and many more through paid plugins.

Widgets vary widely in complexity. Some have dozens of settings, whereas others you simply turn off or on. But no matter how complex the Widget, they appear in your administration screen as a simple box that you just drag and drop. You drop them into Widget Areas that are coded into your theme files—in the sidebar, the header, the footer, and any other spot theme developers can dream up.

For that reason, the available Widget Areas can vary depending on your theme. Some themes and plugins even enable you to create your own custom Widget Areas.

If a Widget Area is empty, most themes collapse that part of the screen. However, for a side- bar, if the theme layout calls for a sidebar, there will be a space where an empty Widget Area exists. Some themes show placeholder widgets if you don’t include any.
