问题
I'm trying to understand the how CSS pixels relates to CSS points nowadays and what I've read is that one css point is a 3/4 pixel. Is that correct? And I can ignore the old idea that 1pt would be 1/72 of 1in because of difference in resolution and physical monitor sizes.
If I want to convert css points to pixels a formula could look like this then? Xpt/75*100 = Ypx
And if want to convert pixels to points the formula could look like this: Xpx -25% = Ypt
回答1:
It depends on your screen resolution and how many pixels per inch you have (often referred to as dpi instead of ppi) - as you say 1pt is 1/72 of an inch.
As most monitors are 96dpi that means that 1pt = 72 / 96 = 0.75 pixels
