I have a couple images on my site that I’ve uploaded at a large scale so they will display properly on retina screens. My problem however is that the same images look really jagged on regular, non retina screens. How can I ensure the quality is consistent between screens?
link to your png doesn’t work.
You can work with media queries for this, where you define different image sizes for different screen sizes. Have a look at: https://css-tricks.com/snippets/css/media-queries-for-standard-devices for more information.
