Thanks for reaching out for assistance. What you are viewing is the Like Box/Page Plugin that is placed on the site page in an iframe and is delivered to your site directly from Facebook.
Unfortunately there is not a lot of styling available with elements in an iframe but you should be able to center the entire Like Box/Page Plugin element by using either of these two Custom CSS snippets indicated below…
You can accomplish this by adding the following to the plugin’s Custom CSS section which is located by going to your WordPress Dashboard – Facebook Feed – Customize – Misc (tabbed page) – scroll down to the Custom CSS section and place the snippet in the Custom CSS box – Save Changes on the page:
.cff-likebox { text-align: center; }
.cff-likebox .fb_iframe_widget { width: 500px !important; float:none; }
or this:
.cff-likebox { text-align: center; }
.cff-likebox div { width: 500px !important; float: none; }
It’s would not be possible to make this element full width unfortunately as Facebook limits the maximum width to 500px.
Have a great day.
