in your html down btn

<button type="button" class="btn btn-dark" onclick="downEvent()" id="down_btn"><iconify-icon icon="ri:file-download-line"></iconify-icon> Download code</button>

and in js

function downEvent() {
  var elem = document.getElementById("copy").innerHTML;

  elem = elem.replace(/\n/g, "")
  .replace(/[\t ]+\</g, "<")
  .replace( /(<([hr]+)>)/ig, '')

  var file = new File(["\ufeff"+elem], 'readme.md', {type: "text/plain:charset=UTF-8"});

  url = window.URL.createObjectURL(file);

  //create a hidden link and set the href and click it
  var a = document.createElement("a");
  a.style = "display: none";
  a.href = url;
  a.download = file.name;
  a.click();
  window.URL.revokeObjectURL(url);
}

You can use the following code to download a HTML file -

function download(filename, text) {
  var element = document.createElement('a');
  element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));
  element.setAttribute('download', filename);

  element.style.display = 'none';
  document.body.appendChild(element);

  element.click();

  document.body.removeChild(element);
}
