Single Post Widget Content

Comment on SEO Recent Posts WordPress Widget by Susanne.

I am trying to add content to this widget on my ‘edit post’ page and want the content to be centered. Is this possible? How? The following is the code I am using.

Am I missing something or is it not possible to center this content? Since it appears in the sidebar and everything else in my sidebar is centered it looks ridiculous if it is not the same.

Thanks for the help and keep up the good work.
