Jquery – Change gradient Values on click / Pressed

The link will show you what I’m trying to achieve

(this is not a real outcome. this video is a concept of my goal)

https://www.youtube.com/watch?v=U_MggL4-AMc

I could really do with a helping hand on this lol

(I need to be able to do this for MULTIPULE different gradients individually)

I’ve tried using Vars with colours and using a Event listener which worked somewhat in codepen with solid colours not gradients but didn’t work on my actual site. (this didn’t previously work for me.

I have now tried using background images to somewhat success. I’m now trying to figure out how I can go back and fourth with the theme colours as well as set the scale for the background retrieved by the script. (however I’d prefer the original method of changing gradient values on click)

here’s a link to the CodePen

    Some issues in your code:

    a) <div> around button is not closed.

    My idea to do it (jQuery way):

    a) Apply the initial CSS to direct body, not with its id. So that you are able to over-Write it further.

    b) Apply onclick on the parent div directly,and pass its object into function as well.

    c) Add a data-class attribute on each parent div and add a corresponding class to it.

    d) when the function called, get this data-class value and add it to the <body>.

    e) Based on this class either add background-imgae CSS or use gradient Css.

    Sample working snippet:

    function myFunction(obj) {
  $('body#Background').removeClass().addClass($(obj).data('class'));
}
    body {
  width: 100%;
  height: 100vh;
  background-repeat: no-repeat;

    Add data-attribute of colors you want to use on btn, then read data-attribute in click event and change css variables.

    const changeTheme = ({ currentTarget }) => {
  document.body.style.setProperty("--clr1", currentTarget.dataset.clr1);
  document.body.style.setProperty("--clr2", currentTarget.dataset.clr2);
};
document.querySelectorAll(".theme").forEach((btn) => btn.addEventListener("click", changeTheme));
    body {
  height: 100vh;
  --clr1: #4e0000;
  --clr2: #b50000;
}

body {
  background: repeating-linear-gradient(45deg, black, black 5px, transparent 5px, transparent 10px), linear-gradient(0deg, var(--clr1), var(--clr2));
}
    <button class="theme" data-clr1="#4e0000" data-clr2="#b50000">Embers</button>
<button class="theme" data-clr1="#202020" data-clr2="#575757">Darkmode</button>
