Style sheet won't work

I've simply just changed the top bar colour to Red, but nothing happens. This is how it looks on the sheet:

html { border-top: 20px solid #red;

Also changing the border as shown in the video doesn't appear to work

Did you put a closing curly brace "}"?

Also, if you use the color "red" you can't have the # tag. That only goes before Hex color codes.

If you just want to change the color to red than it should look like this: 

html {
  border-top: 20px solid red;
}

You don't need the hashtag symbol when using built in css colors. Only when using hexadecimal values.

Adjusting the CSS should change the appearance as soon as you reload the page, if the stylesheet is correctly linked to the html file. Do you have this line in the <head> section of your html file? (And is your CSS file named "style.css"?)

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

<head> <meta charset="utf-8"> <title>All About Pete's Page</title> <link href='http://fonts.googleapis.com/css?family=Open+Sans' rel="stylesheet" type="text/css"> <link href="style.css" rel="stylesheet"> </head>

The <head> section looks like this. And yes my CSS file is named style.css.

red doesn't need a hashtag. Only hex colors do.

Grrr. '#' is not a hashtag. An identifier that begins with one might be, but RGB color values are also not hashtags.

Thanks for the suggestions guys! My CSS sheet now looks like this under top bar colour:

html { border-top: 20px solid red; }

But still the changes don't appear when I click preview. I have also tried refreshing the page once it's opened. The index changes are made, but not the CSS changes. Any other ideas?

If your "CSS sheet" is a separate file, are you sure you are referencing it correctly from the html file?

/***********************************************

Top bar color

***********************************************/

html {

border-top: 20px solid red;

}

This is how the CSS sheet looks when first opened. All I've done is change the hex colour to red. I was wondering whether the CSS sheet is linked to the HTML file, but it in the video, Joy just makes her adjustments to the CSS sheet and the changes appear in the preview.
