How to center align the reviews iframe?

Hello,

Can you provide with a link to your site so that I can see the CSS classes that need to be adjusted?

Sure! Here’s the book page where it’s in use. Thank you for having a look!

You can try this…

#goodreads-widget {
    width: 65% !important;
    margin: 0 auto;
}

That worked out! Thank you so much!! ??
