[Resolved] Generte press and woocommerce

Hi I am currently styling this website

https://thetwistedcurry.co.uk/wordpress/

Under our curry range it is displaying the most popular products. I have added one image while developing.

I want the image to be a least a circle via css or even better a circle around a image circle as the icons above.

I have tried add CSS but no luck, any ideas?

Thanks you
