网页元素位置错乱 点击“审查元素”恢复

原先网页都正常显示的，后来include了一个在线客服.php进来。
Firefox、IE11、360兼容模式中正常；360极速模式、Google Chrome中就会错位，但是点击右键“审查元素”就又都会恢复正常...
请问是什么原因？

下面是include进来的一个div

<DIV id=kefu onmouseover=toBig() onmouseout=toSmall()><TABLE style="FLOAT: left" border=0 cellSpacing=0 cellPadding=0 width=157>  <TBODY>  <TR>    <TD class=main_head height=39 vAlign=top> </TD></TR>  <TR>    <TD class=info vAlign=top>      <TABLE class=qqtable border=0 cellSpacing=0 cellPadding=0 width=120       align=center>        <TBODY>        <!-- <TR>          <TD align=middle><a href="" target="_blank"><IMG border=0             src="images/kefu/kefu_head.gif"></a> </TD>        </TR>        <TR>          <TD height=5></TD></TR> -->		<TR>          <TD height=5 align=middle><SPAN>机加工-徐工：</SPAN></TD></TR>        <TR>          <TD height=30 align=middle><SPAN><a target="_blank" href=""><img border="0" src="" alt="机加工产品相关请联系我" title="机加工产品相关请联系我"/></a></SPAN></TD></TR>        <TR>          <TD height=8 align=middle></TD></TR>		<TR>          <TD height=5 align=middle><SPAN>计量设备-周工：</SPAN></TD></TR>        <TR>          <TD height=30 align=middle><SPAN><a target="_blank" href=""><img border="0" src="" alt="计量设备相关请联系我" title="计量设备相关请联系我"/></a></SPAN></TD></TR>        <TR>          <TD height=8 align=middle></TD></TR>		<TR>          <TD height=5 align=middle><SPAN>网络-小俞：</SPAN></TD></TR>        <TR>          <TD height=30 align=middle><SPAN><a target="_blank" href=""><img border="0" src="" alt="点击这里给我发消息" title="点击这里给我发消息"/></a></SPAN></TD></TR><TR>          <TD height=5></TD></TR>        <TR>          <TD height=5 align=middle><SPAN>中国数控网官方微信：</SPAN></TD></TR>        <TR>          <TD height=135 vAlign=top align=middle><A href="images/kefu/2d.png" target="_blank"><IMG border=0 src="images/kefu/2d.png" width=130 height=130></A></TD>        </TR>        <TR>          <TD align=middle> </TD></TR></TBODY></TABLE></TD></TR>  <TR>    <TD class=down_kefu vAlign=top></TD></TR></TBODY></TABLE><DIV class=Obtn></DIV></DIV><SCRIPT language=javascript>		客服=function (id,_top,_left){		var me=id.charAt?document.getElementById(id):id, d1=document.body, d2=document.documentElement;		d1.style.height=d2.style.   style="max-width:90%";me.style.top=_top?_top+'px':0;me.style.left=_left+"px";//[(_left>0?'left':'left')]=_left?Math.abs(_left)+'px':0;		me.style.position='absolute';		setInterval(function (){me.style.top=parseInt(me.style.top)+(Math.max(d1.scrollTop,d2.scrollTop)+_top-parseInt(me.style.top))*0.1+'px';},10+parseInt(Math.random()*20));		return arguments.callee;		};		window.onload=function (){		客服		('kefu',100,-152)		}</SCRIPT><SCRIPT language=javascript> 			lastScrollY=0; 						var InterTime = 1;			var maxWidth=-1;			var minWidth=-152;			var numInter = 8;						var BigInter ;			var SmallInter ;						var o =  document.getElementById("kefu");				var i = parseInt(o.style.left);				function Big()				{					if(parseInt(o.style.left)<maxWidth)					{						i = parseInt(o.style.left);						i += numInter;							o.style.left=i+"px";							if(i==maxWidth)							clearInterval(BigInter);					}				}				function toBig()				{					clearInterval(SmallInter);					clearInterval(BigInter);						BigInter = setInterval(Big,InterTime);				}				function Small()				{					if(parseInt(o.style.left)>minWidth)					{						i = parseInt(o.style.left);						i -= numInter;						o.style.left=i+"px";												if(i==minWidth)							clearInterval(SmallInter);					}				}				function toSmall()				{					clearInterval(SmallInter);					clearInterval(BigInter);					SmallInter = setInterval(Small,InterTime);									}				</SCRIPT>

CSS文件是这样的：

某些 id class冲突了！  

太神奇了...不是id class的冲突 也没有在外面包一个div。
原来是放到header.php里面的  现在放到footer.php的最下面就好了...
