title: How to change the title font size in this jekyll theme?
body: <p>I tried to find the "title" section so that i could change the font size. 
  I want to decrease it a little but i have not been able to find it in the main.css file. Maybe i'm not looking in the right file or for the right part to change? 
  Any help would be appreciated.</p>
  
  <p>This is the theme: <a href="https://github.com/daattali/beautiful-jekyll" rel="nofollow noreferrer">https://github.com/daattali/beautiful-jekyll</a></p>
