I have been going crazy with this. It seems to display a bit wider than the container. In my case.. I’m trying to cheat the system and fit the WordPress plugin into an HTML site iFrame. It always seemed to be 10% wider than my iFranme so I was looking to do it in the theme or plugin CSS.
However this morning I played with a few other CSS width settings and forced the theme settings to a thinner width! Whoo Whoo! Loving the product.
