Issues where text highlighted by code (`) is seen down

I would like to emphasize something using code (the use of and). This is the example of my blog.

The height is not matched with other texts. The text in the code is down compared to the other text. When I changed the font size in _variables.scss, $code-font-size. How do I modify the blog?

It is not a Hugo question… And you ask It for the second time.
