How can I change the background color of my shopping cart page in dark mode? I want the background color to be #202124 & all the text + button to be white. I tried 

body#cart main#page {
    background-color:#202124!important;
}

already, but it doesn't seem to work, even after refreshing and clearing the browser cache.

Hope somebody can help me.

Best,

Use this CSS

body.dark-mode {
    background-color: #202124;
}
body.dark-mode #page * {
    color: white;
}

Thanks for your help. I implemented it but it doesn't seem to work 😞

Add this new code to Settings > Advanced > Code Injection > Header

<style>
  body.dark-mode#cart {
    background-color: #202124;
}
body.dark-mode#cart #page * {
    color: white;
}
</style>

Wow! Thanks so much!
