Hi arin_w
You can write the custom CSS. Here is the process. go to dashboard-> apperance -> theme-options -> design-options. Below there is custom CSS, Just click on it. Add your Custum CSS you want.

there is another way to write CSS for the theme. You can simply create child theme for our theme then write all your CSS in theme child style.css file. For more detail have a look here https://codex.wordpress.org/Child_Themes
