Your portfolio and the book.fr interface are ready for ultra high definition screens. If the screen allows, we will display high resolution images with a high pixel density.
You will find that, regardless of the browser's zoom level, the images never appear pixelated. If the browser needs more pixels to display a clear picture, then it will automatically load the picture in a larger format.
You have a 4k / UHD / Retina screen? Test the demonstration portfolio.
