Having trouble linking CSS to my HTML - New User

I thought I was doing this right, but apparently not. I have this as the link to my style.css file (which is in the same folder as the html file).

    <meta charset="UTF-8">
    <meta name="viewport" content="width=index, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <link rel="stylesheet" type="text/css" href="style.css">
    <h1>This is a Test</h1>
    <p>The quick brown fox jumped over the lazy dog</p>

The CSS portion I wrote just to test out looks like this:

h1 {
font-size: 200px;

p {
color: red;

Anyone able to tell me what I'm doing wrong?

Can you add a link to the exercise?

Did you add your !DOCTYPE html and then your html tag at the top of your html page?

Yes. I even started a new project and just copy/pasted an example code and basic css style and its still doesn’t show any of the styling when I run the .html file.

I don’t see anything wrong with it, try double check the name of the css file.

you haven’t add !DOCTYPE in your HTML code?
