Is there a way to modify the variable in order to switch the font of the heading every second using CSS and JavaScript?

I'm trying to create a heading that changes fonts every second, but I'm having trouble changing the variable to set it to another font. Check out my code here.

Despite watching tutorials, everything seemed too confusing.

var root = document.querySelector(":root");
var rootstyles = getComputedStyle(root);
var red = rootstyles.getPropertyValue(--red);
console.log("red: ", red);
:root {
  --red: "verdana";
}

h1,
p {
  font-family: var(--red);
}
<h1 style="text-align: center;">Fortune cookie!</h1>
<p style="text-align: center;">Check your luck by clicking the cookie!</p>

Answer №1

const main = document.querySelector(":root");

const fontsArray = ['Times New Roman', 'Tahoma']
let fontIndex = 0

setInterval(() => {
  main.style.setProperty('--main-font', fontsArray[fontIndex % fontsArray.length])
  fontIndex += 1
}, 1000)
:root {
  --main-font: "verdana";
}

h1,
p {
  font-family: var(--main-font);
}
<h1 style="text-align: center;">Discover your fate!</h1>
<p style="text-align: center;">Click the cookie to reveal your fortune!</p>
