What is a widget anyway? Well, the simple explanation is that it’s a mini-app of sorts. You can use it to do something as simple as run a line of HTML code that displays a follow button in the sidebar of your WordPress blog or it can be a companion piece to a plugin. There are also several widgets that are part of the standard WordPress installation like a calendar, tag cloud and a search button. If you’re looking for a simple way to add functionality to your WordPress website, you may need to look no further than the simple text widget.
