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.
Add functionality to your WordPress website using text widgets and the widget logic plugin. Embed a different YouTube video on each page of your website.
