ssmContentWrap is generated from side slide menu plugin for wordpress but i havent fount any reference which says anything about the dot.
This is the code that adds ssmContentWrap to document:
this.ssmContentWrap=document.createElement("div");
this.ssmContentWrap.id="ssmContentWrap";
while(document.body.firstChild){
this.ssmContentWrap.appendChild(document.body.firstChild);
}
