CSS CSS Basics (2014) Understanding Values and Units Em and Rem Units

Em and rem values challenge in CSS Basics -- Don't understand why it says my answer is wrong?

In CSS Basics, the em and rem challenge, question #2 (have attached code) asks me to determine the em value for a desired font size of 53 pixels, with the parent element being 16 pixels. I divide 53 by 16, and the answer is 3.313 or 3.312, depending on rounding. Why is this answer wrong?

It's showing the wrong challenge if you click "view challenge." The actual one I'm referring to is the one I described above: If the parent element is 16 pixels, and you want the font size in ems to equal 53 pixels, wouldn't you just divide 53 by 16? Answer is 3.313 or 3.312, but doesn't accept either of these.

You said,

the answer is 3.313 or 3.312, depending on rounding.

Remember in the lecture, Guil spoke about being precise with em and rem values. Instead of rounding or truncating, try the exact value of 3.3125em.

Sorry, new here and just learning how things are done. Thanks again, marked your answer "best answer."

Thank you, I was having the same problem.

Glad it helped you, too, Shelly. Sometimes it's the tiniest of details that get in the way, I suppose.
