Modify the style of a h1 using JS


I'm trying to modify the style of an h1 html tag as shown below :

const headline = document.getElementById('headline'); headline.style.border = '4em solid black';

My html file includes an h1 tag as follow: <h1 id="headline">My Day</h1>

It does not run. I don't understand why. Do you guys have any idea ? :)

This code works just fine as shown, perhaps there's something else going on.

You might try making a snapshot of your workspace and post the link to it here.

I launched your workspace, and it still works fine. You might try using a different browser.

Maybe I'm not understanding what you mean by "It does not run." Could you describe what you see when you open the preview?
