Fixed Position floating Div no jitter IE6 IE7 CSS writing

CSS:

body {background-image: url(text.txt); background-attachment: fixed;}

.float_up_controler {position: fixed; width: 58px; height: 58px; right: 30px; cursor: pointer; overflow: hidden; z-index: 9; _position: absolute; _top: expression(documentElement.scrollTop + documentElement.clientHeight - this.offsetHeight - 165); _left: expression(documentElement.scrollLeft + documentElement.clientWidth - this.offsetWidth - 30);}

HTML:

<Div id = "scrollbar_up_controler" class = "float_up_controler" style = "bottom: 165px;" Title = "Back to Top">  </div>

Everyone knows that _ top is exclusively prepared for IE6, but when only the above sentence is added, the floating thing shown in the pull scroll bar of IE6 is jitters, the solution is to add such a statement to IE6:

background-image: url(text.txt);

Note that text.txt does not need to have this TXT file. The TXT file name can be regarded as your preferences, so that we can solve the jitter problem in IE6.
