像素是固定大小的单位，用于屏幕媒体以在计算机屏幕上读取）。像素代表图片元素，你知道，一个像素是一个小正方形在你的屏幕上。


点传统上用于打印介质（要打印在纸张上的任何东西等）。一个点等于1/72英寸。点与像素很像，因为它们是固定大小的单位，不能在大小上缩放。

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.
