I am a new wordpress developer. I have created a few project sites. I am a little confused on which screen sizes to test my sites on to make sure they look great on mobile devices. I have been testing them in Google Chrome’s inspect element and then comparing them to the Elementor Page Builder. However there have been some discrepancies between Chrome Inspect Element and Elementor Page Builder. Any advice/ suggestions on which sizes both width and height to testwould be greatly appreciated.
