What is em in CSS for font size?

The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion.

The padding left and right on .child will be of 27px. That’s 1 time the font-size of our element. Remember: when em units are used on font-size, the size is relative to the font-size of the parent. When used on other properties, it’s relative to the font-size of the element itself.

What are the units of size in CSS?

How are EM units related to font size?

Let’s break it down as briefly as possible. Summary: em units for the font-size property will be relative to the font-size of the parent element. em units on other properties than font-size will be relative to the font-size of the current element. rem units sizes will always be relative to the font-size of the root html element.

How is the width of an element calculated in CSS?

Then that means that the width and height of the element (defined here as 4em x 4em) would compute to 80px x 80px (20px * 4 = 80px). The key to remembering this is based on what an actual “em” unit is, and where it comes from.
