The plethora of device capabilities—and the quality of the networks they connect to—can make it seem like an insurmountable task. While we can take advantage of browser features to improve loading performance, how do we know what the user’s device is capable of, or the quality of their network connection?

By tapping into this information server side, we can change how we deliver content based on device and/or network conditions. This can help us to create more inclusive user experiences.
