[Plugin: Meteor Slides] Moving meteor slideshow to the middle

Hi,

I’m implemented the meteor slide show plug in on my site (https://www.hikmah.co.uk/site/) I want to move it to the middle like it is on this page; https://osc4.template-help.com/wordpress_28371/

Also where would I define border styles if I wanted to add a border around the slideshow?

Sincerely appreciate the help,

Saeed
