When the program runs, my h1 heading disappears.

When the program runs, the h1 heading I wrote in the html file disappears and only the paragraph with the message is left. How can I make the h1 heading stay above the paragraph?

1 Answer

Using document.write() clears the previous html code. To keep your header, avoid using document.write() or include your header as part of the input for document.write().

To add a paragraph with a given message after the first <h1> element of the page, you could try

let messageParagraph = document.createElement("p");
let messageText = document.createTextNode("Your message here");
messageParagraph.appendChild(messageText);

let headerHeading = document.querySelector("h1");
headerHeading.insertAdjacentElement("afterend", messageParagraph);

where you create a paragraph, add text to it, and insert it after your <h1> element.

If security is not a concern and you want to add the paragraph to the end of the document's body, you could use document.body.innerHTML += "<p>Your message here</p>"; instead.
