Hi, could you please send me the final version of CSS for this exercise, so that I can compare it with mine and notice what my mistakes are?

Hi @JoaqinCs and welcome to the community 👋

For the assessments you can find the solution code together with a marking guide in a folder next to the folder with the starting code on GitHub. For this exercise this would be here: [https://github.com/mdn/learning-area/tree/main/css/introduction-to-css/fundamental-css-comprehension-finished](https://github.com/mdn/learning-area/tree/main/css/introduction-to-css/fundamental-css-comprehension-finished).

For the smaller “skill tests” the marking guide is mostly in the same folder as the starting code.

I hope that helps 🙂

Have a nice day,  
Michael

Hi, Michael:

I have a follow-up question for the Fundamental CSS comprehension. Why is the correct line height 1.5 to place the

## in the center of the header’s content box? How you calculate that number?

Thank you

The forum removed the markup in your post, but I think I know what you’re trying to ask. Otherwise, let me know. 😁

The actual line height will be calculated by multiplying the `font-size` of the element with the `line-height` value. For the header this results in 2em \* 1.5 = 3em. The height of the header content is also define as `height: 3em;` in another selector. So the actual line height and the `height` match, which will result in the vertically centered text.
