Making a website for my Javascript class which tells the user information about their browser and such. I have the technical part down, but line breaks aren't working for some reason and it's making formatting a headache. For example, here is a function that pretty much tells the user's screen resolution and puts it into the empty output div in the HTML

function screenResolution() {
    clearBox();
    document.getElementById('heading').textContent = "Screen Resolution";
    document.getElementById('output').textContent = "Width: " + screen.width + "Height: " + screen.height;
}

I'm wanting to put a line break inbetween Width: xyz and Height: xyz so it looks like

Width: 1920

Height: 1080

but using \n or <br> both don't seem to be working. It'll just put the tags in like they're strings so it'll look like

Width: 1920<\br>Height:1080

Any help?
