Use CSS selectors to style elements

[rachelnomad]

It is done as it should be, but still not working. anyone can help?

Not sure, but it might be because you used <Style> instead of <style>.

[rachelnomad]

True, I fixed it. Thanks

In that case, it’s a bug in the tests:

Tag names for HTML elements may be written with any mix of lowercase and uppercase letters that are a case-insensitive match for the names of the elements given in the HTML elements section of this document; that is, tag names are case-insensitive.

W3 HTML spec - Case insensitivity in tag names and attribute names

With that said, by far the most common style for HTML tag names is <tag>. <TAG> is a distant second, and <Tag> is almost unheard of.
