align slideshow to center

Did you use a code snippet to change it when you customized?
Had the same issue – here is the code snippet I used at the top of the code.
I.E., went in and clicked on customize, picked the slideshow I wanted – in my case, light, saved with a new title and added this code, then chose this in the default slideshow settings, and updated. It worked. Yes, still clear cache. Post whether or not it works.

.slideshow_container {
margin: 0 auto; /* This centers the slideshow, if the slideshow has a maximum width. */
}
