First of all, you need to select HTML tag and then make a copy of it through the cloneNode(true) method, you must add true to copy its children

then you can edit your cloned HTML as you want (delete elm - edit elm and so on)

therefore you gotta convert it to a string through (.outerHTML)

after that, you have to create a new instance of Blob Object and append the stringified content in it and add the type of your file

const file = new Blob([content], {type: 'text/html'});

then you will need anchor tag to create the download link of you HTML file

a.href = URL.createObjectURL(file);

then trigger anchor tag to be clicked if you clicked the button tag

that's all I hope this snippet clarify my answer more

// select button
const btn = document.getElementById('btn');

// add click event
btn.addEventListener('click', () => {
    // Select anchor
    const a = document.getElementById('a');

    // select html tag
    const html = document.querySelector('html');
    // clone html
    const clonedHtml = html.cloneNode(true);

    // select elements
    const body = clonedHtml.querySelector('body');
    // wipe out body
    body.innerHTML = '';

    // create div
    const div = document.createElement('div');
    // add text
    div.innerText = 'new div';
    // append div
    body.append(div);

    //* append to content
    let content = `<!DOCTYPE html>`;
    content += clonedHtml.outerHTML;
    console.log(content);

    // create HTML file
    let file = new Blob([content], {
        type: 'text/html'
    });

    // add href link
    a.href = URL.createObjectURL(file);
    // name file
    a.download = 'New.html';
    // run click
    a.click();

});

<div class="div1">1</div>
<div class="div2">2</div>

<button type="button" id="btn">Generate HTML file</button>
<a id="a" href="" style="display: none;"></a>
