i think you got an error on this page

The answer is: h2 { font-size: 3.13em; }

Right? But the changes i make in css doesn't effect preview page, no matter what i do. And as a result i can't go to the next step!

Dmitrii;

Welcome to Treehouse!

It looks like you have the wrong value and, for this challenge we do not want to round our value. So for a parent value of 16px, and a target value of 53px we wind up with 3.3125em. (53 / 16 = 3.3125)

Make any sense?

Happy coding,
Ken

Hey Dmitrii.

The page is fine. The problem is you rounded down the value, and CSS doesn't like that and the challenge's code checker doesn't like it even more :)

The value you need is 53/16 = 3.3125

Keep Coding! :)

Thank you Jason and Ken for such a quick response! You guys are great! My calc app rounded this value to 3 decimal automatically:)
