Dark Mode Link Contrast HTML/CSS

I'm a false beginner with HTML, CSS, and Javascript (having done KhanAcademy stuff in the past but also having forgotten most of it). I'm working on trying to get a simple webpage with dark mode going (with as little Javascript as possible). The problem is, the links have low contrast in dark mode. I'm using this code to add a class of .dark-mode to the body element of my html and style it with CSS.

Javascript:

function myFunction() {
    var element = document.body;
    element.classList.toggle("dark-mode");
 }

CSS:

html, body {
    background-color: ivory;
    color: black;
}

.dark-mode {
  background-color: #142514;
  color: blanchedalmond;
}

button.right {
    float: right;
}

HTML:

<button class="right" onclick="myFunction()">Toggle Dark Mode</button>

I tried adding this to CSS, but I realize that the tag isn't getting class="dark-mode".

CSS:

a.dark-mode:link { color: lightskyblue; }
a.dark-mode:visited { color: #6d4b8d; }
a.dark-mode:hover { color: #ffffff; }
a.dark-mode:active { color: #ff4040; text-decoration:none; font-weight:normal; }

Could someone please help me figure out a method that is light on Javascript to either add the dark-mode class to the tag as well as to the body or specify that the tag should get these attributes when the body has the dark-mode class? Any help would be greatly appreciated.

The problem is that you are toggling a .dark-mode class on your <body/> element, but you are writing your CSS selectors as though they themselves would have a .dark-mode class.

This selector:

a.dark-mode {}

...would target an element that looks like this:

<a href="mysite.com" class="dark-mode">Link</a>

Because you want to target all anchors inside a <body/> with a class of .dark-mode you'll want to rewrite your selectors as:

.dark-mode a:link { color: lightskyblue; }
.dark-mode a:visited { color: #6d4b8d; }
.dark-mode a:hover { color: #ffffff; }
.dark-mode a:active { color: #ff4040; text-decoration:none; font-weight:normal; }

...which matches all anchors inside an element with class .dark-mode.
