CSS CSS Basics (2014) Understanding Values and Units Styling the Intro Paragraph

Need help with a challenge in CSS Basics

The question asks: give "intro" a unitless line-height that's 1.6 times larger than the font-size value. The font-size value is 1.25em. I multiplied 1.6 and 1.25 which equals 2 but the code challenge says it's wrong. Am I doing the math wrong or is it a something wrong with the code challenge? Thanks in advance for the help!

Its somewhat of a trick question the answer is 1.6. 

/* Complete the challenge by writing CSS below */
.intro {
  font-size: 1.25em;
  line-height: 1.6;
}

The reason is, its 1.6 is because:

Unitless Line Heights

The recommended method for defining line height is using a number value, referred to as a "unitless" line height. A number value can be any number, including a decimal-based number, as is used in the first code example on this page.

Unitless line heights are recommended due to the fact that child elements will inherit the raw number value, rather than the computed value. With this, child elements can compute their line heights based on their computed font size, rather than inheriting an arbitrary value from a parent that is more likely to need overriding.

I hope this helps.

You don't need to do math on this one. 1 em equals your element current font size. So 1.6 of that is just 1.6em.
line-height: 1.6em; should do the trick :)
