Alone, CSS is not powerful enough to perform functions such as adding commas to currency when they are displayed on the screen and remove commas when they are stored in instances within the model.

Every last trifle we touch and consume, right down to the paper on which this magazine is printed or the screen on which it's displayed, is not only ephemeral but in a real sense irreplaceable.

我们触及和消费的全部琐碎，从纸质杂志的印刷纸张到电子杂志所需的显示屏幕，不仅短暂，而且真正无法被替代。
