Hello!
I am likely being dim, sorry!
Not done website building in years, hence using Wordpress thinking it would be easier.....yeah....lol
So i have generated my facebook page plug in code, added a javascript, CSS and HTML code plugin to enable this feed to work and it does, yippee!! BUT....

i need it to be in the centre of the page but as i have used the HTML code box on wordpress i cannot adjust it's position but i see within the plugins code there are the added sizes i opted for but no option to place in the centre of the page.
I have placed it within a wordpress column but that hasn't helped with this situation so i have copied and pasted the code below and if anyone can advise me of where and what to put within that code to make it move to the centre of the webpage i would be beyond grateful!

I've tried things but they haven't worked, my fault i am sure so any help greatly appreciated, Thank you
