Compuzzled: Saying I have error on a line I don't even have

So confused about this error message directing me to look at Line 650 when I don’t even have a line 650?!!

I’ve also tried the couple of basic things like just deleting it… And the error then repeats itself to the one line of code beyond what I’ve written… Anyone see any glaring errors that I’m missing ??

The entire part of my CSS for this section looks like this:

/Copy Write/
p{
margin: 0 0 10px;
}
*{
margin: 0;
padding: 0;
}
*{
webkit-box-sizing: border-box;
moz-box-sizing: border-box;
box-sizing: border-box;
}
p{
display: block;
margin-block-start:1em;
margin-block-end:1em;
margin-inline-start: 0px;
margin-inline-end: 0px;
}

This is for the Ruby create your own Porfolio project but the Ruby is Rubying is fine. LMK if you need more info to help me trouble shoot my CSS problem.
