Menu
I have the following code:
<head>
<title></title>
<link rel="stylesheet" href="./styles/darkula.css">
<link rel="stylesheet" href="./styles/github.css">
</head>
<body>
<div class="container">
<pre>
<code class="html">
<button class="button is-primary">Primary</button>
</code>
</pre>
<!-- Change theme button -->
<button onclick="changeTheme()">Change theme</button>
</div>
<script src="highlight.pack.js"></script>
<script>
hljs.initHighlightingOnLoad();
document.querySelectorAll("code").forEach(function(element) {
element.innerHTML = element.innerHTML.replace(/&/g, "&").replace(/</g, "<").replace(/>/g, ">").replace(/"/g, """).replace(/'/g, "'");
});
function changeTheme() {
...
}
</script>
</body>
I am loading 2 themes in my file. Because the github theme is being loaded after the darkula theme, it gets applied to all the code elements automatically. This is fine, but I would like to allow users to dynamically change the theme to darkula with the click of the button. I could not find anything in the documentation. How can I do this?

If you are using sass/scss and handle your dependencies with npm, you can do the next thing:
@use "sass:meta";
html[data-theme="light"] {
@include meta.load-css("highlight.js/styles/a11y-light");
}
html[data-theme="dark"] {
@include meta.load-css("highlight.js/styles/a11y-dark");
}
To make it to work, you need to define the data-theme attribute in your html tag.
<html data-theme="light">
<!-- ensure to change it with javascript and define one with default -->
...
</html>
