Improve this question The blurriness of the flag icon in the intl-tel-input plugin on WordPress could be due to several factors: Image Resolution: The flag icons might be low-resolution images, leading to blurriness, especially on high-DPI (Retina) displays. You may need to replace them with higher-resolution versions. To fix the blurry flag icon issue in the intl-tel-input plugin on WordPress, you can apply the following CSS code: .iti__flag { background-image: url(https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/23.8.1/img/flags@2x.png) !important; } This code uses a higher resolution image (flags@2x.png), which should eliminate the blurriness on high-DPI (Retina) displays, ensuring that the flag icons appear sharp and clear.
