It is, but requires a CSS2 capable browser (all major browsers, IE8+).

.OwnerJoe:before {
  content: "Joe's Task: ";
}

But I would rather recommend using Javascript for this. With jQuery:

$('.OwnerJoe').each(function() {
  $(this).before($('<span>').text("Joe's Task: "));
});

Adding external css file to html doc
styles.css is not a magic file that exists implicitly. That's a placeholder for the name of a file that you must create. Make a styles.css file, put it in the same directory as the HTML document, then put the styles in that stylesheet file. More on reddit.com

What's the easiest way to link HTML and CSS files for practicing?
This one is fairly easy bud, say for instance you create a folder on your desktop for shits and giggles. Name it whatever you want of course, now create your html file and your css file in that folder together, the key is they have to be in the same directory, hence the folder. Then: where href="mystyles.css" just rename what's in quotes to the path of the css file and voila. Also in case forgotten, that goes in the head of your html. More on reddit.com

June 1, 2022 -

I feel stupid and like I have taking 3 steps back in my learning. I am trying to figure out the 3 different implementations of css. Doing External now. Just trying this super simple code, the colors did not show up in the browser like they did on w3schools.

<!DOCTYPE html>

<html>

<head>

<link rel="stylesheet" href="styles.css">

</head>

<body>

<h1>This is a heading</h1>

<p>This is a paragraph.</p>

</body>

</html>

Is it because I don't have a css file on my computer? Do I need to download one? Copy and paste from somewhere? I don't get it. I prefer building with the css and html on the same document because I haven't learned how to do anything else yet. I have been able to follow tutorials fine but for some reason, now it's not clicking.
