Urgently looking for website floating code that is compatible with IE and Firefox! (The parsing of IE9 and IE5, 6, 7, and 8 is different)_html/css_WEB-ITnose

My existing code is only compatible with IE8 and below. IE9 and Firefox are not compatible. Please help me! !

<div id="codefans_net" visibility: visible; border:#A3DFF7 1px solid;></div><script language="JavaScript" type="text/javascript">    var x = 50, y = 60    var xin = true, yin = true    var step = 1    var delay = 10    var obj = document.getElementById("codefans_net")    function float() {        var L = T = 0        var R = document.body.clientWidth - obj.offsetWidth        var B = document.body.clientHeight - obj.offsetHeight        obj.style.left = x + document.body.scrollLeft        obj.style.top = y + document.body.scrollTop        x = x + step * (xin ? 1 : -1)        if (x < L) { xin = true; x = L }        if (x > R) { xin = false; x = R }        y = y + step * (yin ? 1 : -1)        if (y < T) { yin = true; y = T }        if (y > B) { yin = false; y = B }    }    var itl = setInterval("float()", delay)    obj.onmouseover = function() { clearInterval(itl) }    obj.onmouseout = function() { itl = setInterval("float()", delay) }    function close_float() { obj.style.visibility = 'hidden'; }</script>

Really! If you were asked to build a portal for a certain website, would you only consider users below IE8, but not IE9 and Firefox users? !

The problem with your code is that xx.style.top(left) is recognized by IE6, 7 and 8, but others such as FF, Google and IE9 are not recognized ~

The solution is to add 'px' after your value to achieve compatibility~
