style.css code showing up in the theme title in theme selector

I’m not sure why this is happening, since I’ve done this before, but my entire style.css file is showing up in the theme selector. https://i38.tinypic.com/20rr78p.png

My stylesheet can be found at https://www.mildlyhotpeppers.com/comics/wp-content/themes/mhp_2_2/style.css.

The header starts like this:
@charset “utf-8”;

/*
Theme Name: MildlyHotPeppers
Theme URI: https://www.mildlyhotpeppers.com
Description: The official glossy theme for MildlyHotPeppers.com
Author: Josh Ma
Author URI: https://joshma.com
Version: 2.2

*/

Has this happened to anyone?

//edit
Nevermind, I just copied and pasted the stylesheet from the previous version of the theme – seems like the header was the same, but I must have forgotten to close a comment somewhere down the line.
