I could have sworn a task was open but can't find one.
Good news is we can have a night mode with a few lines of CSS
Developer notes
Night mode could be enabled via an inline script at the top of the page when a cookie/localStorage item is set.
body, img, video, svg { filter: invert( 1 ), hue-rotate( 180deg ); } body { background: #000; }
I thought I was smart and the first to think of this, but of course turns out someone beat me to it > https://lnikki.la/articles/night-mode-css-filter/
