Widgets are special WordPress plugins that add small blocks of functionality to the sidebar of your website.
In the past, modifying the sidebar required mucking around with a theme’s PHP code. Fortunately, WordPress widgets eliminate the hassle by allowing anyone to easily customize their theme’s sidebar with drag-and-drop ease.
The WordPress community has developed a large and growing collection of widgets that will allow you to plug all sorts of things into your WordPress sidebar. From Flickr photos to your Twitter status, if there’s something you’d like to add to your blog sidebar, chances are there’s a widget to help you do it.
This video introduces you to WordPress Widgets, explains how to use them, and where to find new widgets to spruce up your website. You’ll also learn what to do when widgets suddenly vanish — a problem that may occur unexpectedly when you change themes.
