What to do when apple tv zes while updating
But as a start I would recommend reading some info on Mobile First CSS Mobile first design, in essence says you start with the small screen and design up. Even though it actually has 750 physical pixels across. Applying the point value (375) or in effect reversing the multiplier ratio effect.So working with px in css will tell you if they are using a mobile, but it will not tell you if the user is using a high resolution screen. CSS will never know the user is using a retina or high res screen unless we check the “ ?This is why Points are more related to physical size than pixels. The red line below represent the original i Phone pixel.You can see that on the more modern i Phones, that pixel would look incredibly small. Or in the Android world, this is called the Density Independent Pixel (dp).So Apple borrowed a term from the world of print, “Points”. A screen is a digital form of print and your images and UI need to be readable and crisp.Taking 163 PPI (original i Phone PPI) as their benchmark, they would give all future screens a multiplier ratio so the photos/graphics took up the same physical space regardless of the screen density. Which means they must be an appropriate physical size.A smaller pixel means you can squeeze more detail into the same physical space, this gives more clarity to images and text.
Maybe you have a full-width background image or hero image. Firstly let’s make it clear that I am talking about bitmap images here. Lets start by talking about points and pixels, the building blocks of all digital and print images. Especially in recent years when Apple changed their reference in screen sizes from pixels to points.
Design in x 1, then apply your multiplier at the end.
For instance, the i Pad benchmark is the non-retina i Pad 1 and 2.
A Pixel is = a single group of coloured dots on a screen A vital point to remember about pixels is they do NOT have a uniform size.
That’s why we measure DPI/PPI (Dots per Inch or Pixels per Inch) Why does an i Phone 7 Plus have 401 PPI, whereas a 60inch Full HD Samsung TV has a PPI of 37?
You can see that as long you apply the correct multiplier factor, the Apple point or dp remains the same physical size.
