Hi Annie, thank you for reaching out with your BoldGrid questions!

Yes, you can resize a search widget in your header to make it smaller using a few different methods depending on your theme and how the widget is currently styled.  If you could link us to your website so that we can inspect your search widget we’ll give our best suggestions to resize it in your header!

Thank you, we look forward to assisting you further with this!

Thanks Annie,

To resize the widget you may need to add custom CSS.  This would involve inspecting the search widget using your chrome dev tools and finding the class that styles the widget and modifying it in the WordPress Customizer’s custom CSS section.

We have a guide on using the Custom CSS editor that might be helpful to you.  Otherwise if you can place the widget on a test page we can inspect it directly come up with the CSS for you.

Thank you Annie! Let us know if you have more questions!
