How can I default this to dark mode? & also default to list mode?

[TomLewis]

Sorry I'm brand new to Hugo (And static generators as a whole!) and I'm starting with this theme as I love the look of it!

Is there a setting/config option to default to the dark mode & set the default posts view to list mode?

You can change the default mode by editing assets/js/initColors.js

function initColors(){
    if (localStorage.getItem("isLight") === null) {
        localStorage.setItem("isLight", 'true'); <- change to false for dark mode by default
    }
