Created a child to remove date/time [fixed]

I manged to fix it. In case anyone else is dumb like me, I didn’t realize I had to edit it in WordPress after uploading it, I was uploading with the code in it.
Sorry.

My site is http://liquidgrooveband.com/ and I am using Responsive. I am attempting to create a child directory, but when I use it, it does not remove the date.

I do not know exactly where to paste the code because I still see the date and time when I do switch to the child css, and I have made it like this:

/*
Theme Name: Responsive Child Theme
Theme URI: http://cyberchimps.com/guide/child-theme-example/
Description: Responsive Child Theme
Template: responsive
Version: 1.0.0
Author: CyberChimps
Author URI: https://cyberchimps.com/
License: GNU General Public License
License URI: license.txt

*/

/* =Hide whole post meta
-------------------------------------------------------------- */
.post-meta {
    display: none;
}
/* =Hide "Posted on"
-------------------------------------------------------------- */
.post-meta .posted {
    display: none;
}
/* =Hide date
-------------------------------------------------------------- */
.post-meta .timestamp {
    display: none;
}
/* =Hide "by"
-------------------------------------------------------------- */
.post-meta .byline {
    display: none;
}
/* =Hide author
-------------------------------------------------------------- */
.post-meta .author {
    display: none;
} */

Please let me know what I’m doing wrong, thanks.
