I understand your questions like You wanna make code blocks in HTML Screen.

maybe You should see this article. https://css-tricks.com/web-component-for-a-code-block/

and make user input or textarea for typing code ...

    <div>
      <input id="textElm" />
      <br />
      <code id="codeElm">hi</code>
    </div>

const input = document.getElementById("textElm");
const code = document.getElementById("codeElm");

input.addEventListener("change", (e) => {
  console.log(e.target.value);
  console.log(code)
  code.innerHTML = e.target.value;
});
