JavaScript: Dynamic Font Size Based on Device Pixel Ratio
This code checks if the document's ready state is 'complete'. If it is, it sets the font size of the body element to 14 times the device pixel ratio (dpr) in pixels.
If the document's ready state is not 'complete', it adds an event listener for the 'DOMContentLoaded' event. When this event is fired, it sets the font size of the body element to 14 times the device pixel ratio (dpr) in pixels.
