Question: is pt and px the same?
Answer: So 1 pt = 1/72 inch. Therefore, on a 72 ppi display, 1 point = 1 pixel. A pt is 1/72 of an in, and a px is 1/96 of an in. ... In CSS, everything is somewhat abstracted, so a unit such as a "pt" is not necessarily one point in physical size, especially on a screen, an "in" is not necessarily one inch in size, and so forth.
