About

Does It Fit is a responsive design checker. You paste any URL or your localhost, and it tries the site on 123 real devices, from phones and tablets to laptops and monitors, each at its exact CSS viewport, then tells you where it spills. You can put its stickers on your own site, compare devices, and ask your AI if a page fits, and the site carries guides on viewports, breakpoints and mobile fixes.
