This allows a layout with specific CSS dimensions to be displayed in a consistent way across screens with similar physical dimensions, but different numbers of hardware pixels making up that screen.ДЇor devices with high-resolution screens, manufacturers define a device pixel ratio based on their screen size and resolution. If you are packing more pixels into a smaller space, those individual pixels will have to be smaller to fit - this means that the size of a hardware pixel can vary significantly from one device to another.Д¬SS pixels, on the other hand, are designed to be roughly the same size across devices. The more individual hardware pixels that a screen has in a given screen size, the higher the resolution and the clearer that display will look.

Hardware pixels are the number of individual display pixels (essentially dots of light) that make up a specific screen.

To allow websites to display in a readable way on these screens, Apple created separate concepts for hardware pixels (sometimes referred to as display pixels or screen pixels) and CSS pixels (which are sometimes called software pixels). When Apple introduced Retina displays in iPads and iPhones, the pixel dimensions of these devices frequently were significantly larger than most existing full-size monitors while the physical screen sizes of these new devices were much smaller.

Hardware pixels, CSS pixels & device pixel ratio High-resolution images for Retina displays.Hardware pixels, CSS pixels & device pixel ratio.Weight in general is also important: A stylus thatвЂ™s too heavy cramps your hand over time, and one thatвЂ™s too light suffers from the same problems as a slicker pen nib-you donвЂ™t have the same control over your lines. This is especially true for styluses that donвЂ™t support palm rejection, which means you have to keep your hand upright over the pen. Balance and weight: A stylusвЂ™s weight should be distributed evenly along its body-a stylus with most of its weight at the nib and little at the other end (or vice versa) is uncomfortable to hold and difficult to control.If itвЂ™s too sticky, you might make erroneous marks or get sore hands from gripping the stylus more tightly to drag it across the screen. If the nib is too slick, you donвЂ™t have the line control that you might get with a pen on a piece of paper. Resistance: A good stylus offers the right amount of friction between the nib (drawing end) of the stylus and the iPadвЂ™s screen.However, if a stylus cramped a testerвЂ™s hand or dug into skin, we dropped that model from consideration, and if we found it impossible to grip a stylus without dragging a hand on the screen or contorting our fingers, we eliminated that contender.

Comfort: Recommending a single stylus design and grip for everyone is difficult some people prefer a thicker body, for example, while others want rubberized grips or angled grip surfaces.Advanced features: More advanced stylus models include features such as palm rejection, tilt support, and pressure sensitivity, which make for a better drawing and writing experience.While youвЂ™re drawing, the stylus should ink over the same line precisely and repeatedly, and the line on the screen should closely stick to the stylusвЂ™s tip without noticeable lag.

Precision: A stylus should write consistently, without overlapping letters or inconsistent vertical spacing.
