Content Div extends beyond body on some browsers - Joomla! Forum - community, help and support

hi, everybody. i've got page renders on browsers, on opera browser on android, content div, depending on how content in it, can extend outside of body, , past footer. css content div includes following:

code: select all

   
position: absolute;
height: 670px;
    left: 160px;
    max-height: 670px;
    overflow-y: scroll;
    padding: 10px 20px 5px;
   

the body basically:

code: select all

body {
    background-image: url(*******);
}


everything in body inside of centering layer:

code: select all

#layer-center {
  position: relative;
  margin-left: -400px;
  left: 50%;
  top: +0px;
  width: 800px;
  min-height: 800px;
  max-width:800px;
  height:100%;
}


any thoughts on going on , how fix it? thanks.
