Increasing width of BAWKBOX review widget

Site URL: https://www.lightofinfinity.com/testimonials-reviews

Hello! 

Is there an easy way to increase the width of a review widget? Basically it looks good on a smaller screen, but on a large monitor it is very much limited in width and aligned to the left by default. As a result, I've had to narrow the width of that specific page down so the widget can look somewhat normal. If I can get it to decent width, I think it'll look pretty good, even on a larger screen. 

On a phone or laptop size screen (which most people will likely be on anyway) it looks good enough, but it would be nice to fix, if possible. I have limited knowledge with this type of thing, so I'm not sure if this is something that is easy to rectify or not worth the hassle.

Thank you for taking the time to read this and for any assistance you may provide.

Kind Regards,

Luke
