CSS Custom Logo Problems in Encore Template

Hey guys,

I have a website on the Encore template, and I want my homepage to have a CSS logo that scales for the different display sizes (mobile, medium, desktop), but I can't figure out what to do. So far, I've gotten the custom image on the page. Here are the problems:

1. The picture is huge
2. It doesn't scale for the sizes

How do I write the CSS to reflect what I want? Here is the code I have so far:

<style>
#title-area:before {
  content:url(https://images.squarespace-cdn.com/content/56d21057c2ea51b1520ba420/1565749780067-INFEFL7NRFJUSK6FF6QN/?format=1500w&content-type=image%2Fpng);
 }

#title-area img {
    display: none;
}
</style>

Here is the URL to my site: http://austinswansonmusic.com/

Thanks for the help!

you should use background-image: url(logo url); content: ""; width: 50px; height: 50px; display: block;

Where would I put that within the code I currently have? And is this for a background image or a logo?
