The Like Box is a social plugin that enables Facebook Page owners to attract and gain Likes from their own website. The Like Box enables users to:

- See how many already like this Page, and which of their friends like it too
- Read recent posts from the Page
- Like the Page with one click, without needing to visit the Page

A nifty little likebox widget, but the widget comes with an ugly blue border that cannot be overridden with css because it is in a facebook iframe.

The Like button lets a user share your content with friends on Facebook. When the user clicks the Like button on your site, a story appears in the user's friends' News Feed with a link back to your website. There are 2 versions, the iframe version and the XFBML version.

“The Facebook Like button is undoubtedly the most important Social Plugin. It can boost your website traffic significantly and adds up to your website user interaction.”
