Bold in Markdown/Front Matter

Hi all,
I know the basics of markdown syntax and I want to have part of my text in bold editing my frontmatter/markdown file.

**Some Text**

has no effect, while

*Some Text*

works as expected with italics.
The HTML string:

<strong>Some Text</strong>

does not work as well.
Instead, setting bold font in CSS works as expected.
Am I missing something inside Grav configuration?


Solved: I was missing the strong tag in CSS.
