CSS code for "Padding" on site title

This is my first post I hope someone can help me. My website is andypiggott.com. The mobile version of the site title has too much padding(?) above and below. It is fine when viewed on a desktop. Could anyone please help with a piece of CSS to correct this?
Thank you.

Have you added meta tag in the ‘head’?

Thank you for your response but I’m sorry but I don’t know what that means.

I don’t know how to explain. Ok let me rephrase it.
Have you made tags of head and body tags in html page?

Thank you I appreciate your response. I have managed to move the text closer to the logo using css coding and now I am attempting to reduce the space above and below the site title using css.
