Do note this CSS hides a few Endchan-specific "features" for the sake of minimalism (simplicity) and closer mimicry to 4chan/8chan. Remove the below line numbers (corresponding to the pastebin) to un-hide features that you want back for your customized CSS.
Preview links are hidden (lines 134-135):
/* hide post Preview links */
.linkPreview {display: none;}
Del links are hidden (lines 137-138):
/* hide del */
a.delLink, a[href="#bottom"] {display: none !important;}
Hide User are hidden (lines 143-144):
/* hide Hide User */
a[id^="hide"][id*="User"] {display: none;}
[X] is changed to [--], moved to far left like in 8chan (lines 146-168):
/* Replace [X] with [--] and move it far left like in 8chan */
.opHead a[id^="hide"] {
color: transparent;
visibility: hidden;
}
.opHead a[id^="hide"][id*="Thread"]::after {
color: initial;
content: "[--]";
text-decoration: underline;
visibility: visible;
float: left;
}
/* move OP backlinks (reply ID links) leftwards to make up for hiding [X] */
.opHead .panelBacklinks a {position: relative; right: 2em !important;}
/* move reply backlink leftwards for similar reason, be more like 4chan/8chan */
.innerPost .panelBacklinks a {position: relative; right: 0.5em !important;}
/* reduce backlinks padding-left from 0.5em like in 4chan */
.panelBacklinks a {padding-left: 0.4em;}
/* Hide all [X] post hiders (not including OP) */
.innerPost a[id^="hide"] {display: none;}
