I'm trying to create a script on a website that takes the user's location and displays the results. I have a problem with the setting and styles. How can i edit style or how can i edit the code so that it can work with css styles in <div>

my code:

<pre></pre>

<script>
  const address = document.querySelector("pre");


  function onError() {
    address.innerText = "";
  }
  async function onSuccess(position) {
    const geocode = await fetch(`/${position.coords.latitude},${position.coords.longitude}?json=1`);
    const geoResponse = await geocode.json();

    address.innerText = `${geoResponse.country}, ${geoResponse.city}, ${geoResponse.postal}, ${geoResponse.staddress}`;
    
    }
  if (!navigator.geolocation) {
    onError();
  } else {
    navigator.geolocation.getCurrentPosition(onSuccess, onError);
  }
  
</script>

I've created a snippet with your code. In this case, we are targeting a pre element.

const address = document.querySelector("pre");

address.style.backgroundColor = "blue";

address.style.color = "white";

address.style.fontWeight = "900";

pre {
  height: 500px;
  width: 500px;
}

<pre>This is a pre element</pre>

However, if you wanted to target a class, you would do this:

<div class="pre"></div>

const address = document.querySelector(".pre");

For id you would do this:

<div id="pre"></div>

const address = document.querySelector("#pre");

When you use id or class you can still target your styles the same way:

address.style.backgroundColor = "blue";

address.style.color = "white";

address.style.fontWeight = "900";

More info here.

document.getElementById(id).style.property = new style

in your case:

const address = document.querySelector("pre");

address.style.color= "red"
