A simple WordPress plugin which adds a “scroll to top” button to the bottom corner of the page if the page has been scrolled down. It is compatible with all major browsers and should work with all themes, including
responsive and high resolution themes.

It is possible to configure the plugin in the admin area for choosing between light or dark colour schemes and size of the button as well.

If your theme doesn’t already contain this feature, you can simply add it by means of this plugin.
