The code panel containing the json responses is rather small. I suggest replacing the .multiline { max-height: 200px; } https://github.com/mrin9/RapiDoc/blob/021dfc1bb520fb689bfa4cc7adb4c7210dc0bc0c/src/styles/font-styles.js#L27 by 2/3 of the viewport height: .multiline { max-height: 66vh; }
