[ spoiler ]< p style="text-align:center;color:#00130b;font-family:'ms gothic';font-size:13px;" >< span style="background:rgba(252,249,244,0.9);border:2px solid #c6bfad;float:left;width:90%;height:auto;margin:30px;margin-bottom:10px;margin-top:5px;padding:20px;font-size:13px;color:#505050;" >extra information here, beep boop :*3:[ /spoiler ]< /span >< /span >
