Gift Registry Widget - Adjust Width

I've reviewed previous articles and no luck. I've tried injecting custom CSS on the widget and form.

I'm trying to adjust the width of the gift registry widget on my form:  https://form.jotformpro.com/72214145552954

Please inject this custom CSS code inside the form and not inside the widget:

#customFieldFrame_43 {
width: 400px !important;
}

Here's a guide on How-to-Inject-Custom-CSS-Codes. Here's the result:

Hope that helps. Thank you.
