Including html input fields in docs.md results in these fields systematically appearing on a separate line

[stimilon]

I am fan of this theme to create an interactive tutorial but face a small issue:

If I include this in one of the docs.md:
This is an example of a texte with an input <input type="number" style="color:#20b030; width: 80px" value="10"> to be manipulated by the user.
it results in this:

How can I avoid for the input field to be on a separate file? I would like it to be included on the very same line as the sentence.
Thanks for any explanation/hint.
