   color: #CCC;
   background-position: auto;
   border-bottom-width: inherit;
   border-width: auto;
   position: auto;

#content {
   width: 100%;
   background: #FFF;
   border: thin none #FFFFFF;
   height: auto;
   margin-top: auto;
   margin-right: 20px;
   margin-bottom: auto;
   margin-left: auto;
   margin-right: auto;
   background-position: static;
   border-bottom-width: thin;
   border-width: auto;
   overflow: hidden;
   position: inherit;
   padding-top: 0px;
   padding-right: 0px;
   padding-bottom: 0px;
   padding-left: 0px;
}

h1 {
   margin: 0;

}

hr {
   border: none;
   height: 1px; line-height: 1px;
   background: #CCC;   
   margin-bottom: 20px;
   padding: 0;
}

p {
   margin: 0;   
   padding: 7px 0;
}

.clear {
   clear: both;
   line-height: 1px;
   font-size: 1px;
}

a {
   outline-color: #888;   
}
.scroll {
   overflow:auto;
   position:absolute;
   left:1200px;
   top: 262px;
   width: 567px;
   height: 513px;
   border: 0px solid black
}
div#scrollbar {
    display:block; /* initially display:none; to hide from incapable */
    }


   
div#scrollbar {
   position:relative;
   width:801px;
   height:200px;
   font-size:1px;  /* so no gap or misplacement due to image vertical alignment */
  }



div#down {
   position:absolute;
   left:435px;
   bottom:0;
   width: 600px;
   height: auto;
}

/* for safari, to prevent selection problem  */
div#scrollbar, div#track, div#dragBar, div#up, div#down {
    -moz-user-select: none;
    -khtml-user-select: none;
}


/* so no gap or misplacement due to image vertical alignment
font-size:1px in scrollbar has same effect (less likely to be removed, resulting in support issues) */
div#scrollbar img {
    display:block;
    }
#content h1 strong {
   font-family: "Comic Sans MS", cursive;
   font-size: 24px;
   color: #666;
   width: 100%;
   height: 100%;
}
