CSS CSS Foundations Values and Units Absolute Length Units

Is it necessary to learn Absolute Length Units?

It seems as though these units are fixed and unresponsive. So, if Responsive Web Design is becoming the new standard, do I need to direct much attention to this section?

Yes, you should still know about these values. Many absolute values aren't used much in CSS -- like cm, mm or in -- but we frequently use percentages for layout of page elements, pixels are still commonly used for margins, padding, and border width.

In addition, for print stylesheets you can effectively use pt (points) to define text sizes.
