HTML-CSS Coffee page background-color

[grifway]

Walking through step 26. I am not having a problem inside freecodecamp environment. But - trying same code in vscode I get this weird result.

index.html - simple code

Hello there

main.css:
div {
background-color: burlywood;
}

When I try to run this the simple

tag text is hidden. I am so confused as to what the catch is.
Anyone explain issue please.
Thank you.
