A hardware pixel is the actual dot of light on the screen while the software pixel or CSS pixel is a unit of measurement. This is the ratio of the hardware pixels to the software or CSS pixels. The problem with this solution is that the images are only responsive in terms of the device’s pixel density.
In this example, if the device has a resolution of two device pixels per CSS or more the browser will load the cute-cat-high1.jpg image. Srcset also allows you to serve images at different resolutions using x-descriptors. Note that you are also including src which provides the image to fall back on browsers that don’t support srcset and sizes.

The issue with using srcset is that you have no control of what image the browser will pick to display. Srcset is made of three parts: The image filename which specifies the path to the source image, a space, and the intrinsic or real width of the image. Srcset allows you to provide additional source files, and the browser will choose the image that seems optimal for that image size.
