Really nice site! When flicking through the screenshots in the modal view - before the screenshot loads - how did you get the background gradient to be so close to the actual site's page background? I know you already have the colour scheme in advance, but the gradient seems to match very closely most times. Seems really clever EDIT: Just saw this https://drikerf.com/image-previews-on-klart/ https://drikerf.com/image-previews-on-klart/ which explains it! Really nice trick
