So I wanna preface this with this is my first time posting on this site so if this is in the wrong place, sorry! Also I am hellaciously new to anything regarding CSS.

With that said- I'm trying my hardest to find a way to remove the right column. I've got maps removed, but for the life of me I can't get Stream to remove. I've found some threads here with some code but perhaps I'm just not copy/pasting them correctly, because nothing I'm doing is working.

My current attempt (with all my other coding atm) is the following:

/* REMOVE CAMPAIGN TITLE TEXT AND DEFAULT BANNER */
.campaign-public-layout .campaign-title, .campaign-public-layout #banner-container {display:none;}

/* ADD BANNER IMAGE BESIDE OP DRAGON LOGO */
.campaign-public-layout .campaign-public-title-container {background-image: url("urlofimagefile"); background-size: contain; background-repeat: no-repeat;}

/*Right Column*/
.where-we-game-container, .user-container, .fan-count-wrapper, .become-a-fan-button, .comment-count-wrapper {
display: none;
} 

/*Remove Link*/
#campaign-nav .section file-docker {display:none;}
#campaign-nav .file-docker {display:none;}
#campaign-nav .maps {display:none;}

/*Change Link Names*/
/*remove current text*/
#campaign-nav .adventure-log .nav-text {font-size:0;}
#campaign-nav .wiki .nav-text {font-size:0;}
#campaign-nav .characters .nav-text {font-size:0;}
#campaign-nav .maps .nav-text {font-size:0;}
#campaign-nav .front-page .nav-text {font-size:0;}
#campaign-nav .dashboard .nav-text {font-size:0;}
#campaign-nav .settings .nav-text {font-size:0;}
#campaign-nav .forum .nav-text {font-size:0;}
#campaign-nav .calendar .nav-text {font-size:0;}
/*add new text*/
#campaign-nav .adventure-log a:after {content:"Story";}
#campaign-nav .wiki a:after {content:"Info";}
#campaign-nav .characters a:after {content:"Characters";}
#campaign-nav .maps a:after {content:"Maps";}
#campaign-nav .front-page a:after {content:"Homepage";}
#campaign-nav .dashboard a:after {content:"Dashboard";}
#campaign-nav .settings a:after {content:"Settings";}
#campaign-nav .forum a:after {content:"Fourms";}
#campaign-nav .calendar a:after {content:"Events";}

/* TEXT FONT */
.nav-text,#campaign-nav a:after {
    font-family:'IM Fell English';
    font-size:medium;

Any advice or help that anyone could give would be very apprecaited! Thanks for your time.
