CSS not displaying in browser

I’m in section 5 and 6 of the CSS Basics. I cannot get the css to live render in the live view browser. Is this a program issue or a code issue. Can someone please help me with this?

Here is the code I’ve built:

HTML:

Lorem ipsum dolor sit amet.

Lorem ipsum dolor sit amet.

CSS:
body {
margin: 10px;
}

p.first {
font-size: 140%;
font-style: italic;
}

You don’t appear to have any p tags in your HTML, so the p selector won’t do anything.

Write HTML in a tag ( can be h1, h2, p, or anything)
Let me give an example
less than< p >greater than Lorem Less than < forward slash / greater than >

This will display Lorem on your browser

Now you can style it using CSS as
body {
margin: 10px;
}

p {
font-size: 140%;
font-style: italic;
}
