How would you optimize this code ?
It functions the way I want it to, but I made a lot of copy paste.
Is there a way, specifically for the JS part to write it in a shorter way ?

All opinions welcome…

both for css and javascript, you use the same code again and again. Css, use classes for example

javascript, use functions or loops to use the same logic on multiple elements

As an example, you create a lot of <div> elements like this:

    var div1 = document.createElement("div");
    div1.setAttribute("id","firstResult");
    document.getElementById("voteanswer1").appendChild(div1);
    document.getElementById("firstResult").innerHTML = clicks1 + " votes    " + rel1 + "%";
    div1.style.fontStyle = "Serif";
    div1.style.fontSize = "16px";
    div1.style.color = "#495159";
    div1.style.position = "absolute";
    div1.style.left = "10%";
    div1.style.backgroundColor = "transparent";
    div1.style.zIndex = 2;

First, you don’t have to set all those styles with JavaScript, you can just give it a class and style all the <div> elements with one class, so your JS would be:

    var div1 = document.createElement("div");
    div1.setAttribute("id","firstResult");
    document.getElementById("voteanswer1").appendChild(div1);
    document.getElementById("firstResult").innerHTML = clicks1 + " votes    " + rel1 + "%";

    /* delete all the rest and use a class instead: */

    div1.setAttribute("class", "my-div-class")

And the CSS:

.my-div-class {
  font-family:'Serif';
  font-size: 16px;
  color: #495159;

  /* and all the other repeating styles */
}

That would already remove half of your code.


Next, you create a lot of those divs, you could let a function do that for you, where you only pass in the stuff that changes for each div:
function makeDiv(id, parentId, clicks, rel){
  let div = document.createElement("div");
  div.setAttribute("id", id);
  document.getElementById(parendId).appendChild(div);
  div.innerHTML = clicks + " votes   " + rel + "%";
}

And to call the function:

makeDiv("firstResult", "voteanswer1", clicks1, rel1);
makeDiv("secondResult", "voteanswer2", clicks2, rel2);
/* ... */

You could optmise even further, but the above would already make your code about 90% shorter.
