I don't know why the following is appearing incorrectly in IE 6.0 but fine (the way I want it) in Firefox. Apologies if this is the incorrect forum for this matter and  the long post.

code:

---

html    {
    height: 100%;
    border: none;
    margin: 0px;
}

body    {
    background-color: #000000;
    color: #ffffff;
    height: 100%;
    border: none;
    margin: 0px;
    }
   
.frame    {
    background-color: #000000;
    background-image: url(back.gif);
    repeat: repeat;
    color: #ffffff;
    height: 100%;
    width: 100%;
    }
   
.menu    {
    background-color: #000000;
    padding: 0px;
    height: auto;
}

.body    {
    background-color: #000000;
    padding: 0px;
    height: auto;
}

.padderx    {
    width: 20px;
    height:auto;
}

.paddery    {
    height: 20px;
}
