图片放大方法、、菜单栏的位置随滚轮移动固定方法、、<a></a>去外层虚线方法:a:focus {  outline:none;   -moz-outline:none;};

图片放大方法一:

<style type="text/css">
.xt{ width:230px; height:230px;}
.tp{ width:230px; height:230px; overflow:hidden;}
.tp img{transition:all 1s ease-out 0s; margin-left:0px; margin-top:0px; perspective-origin:bottom;}
</style>

<body>

<div class="tp">
  <img class="xt" onmouseover="Bian(this)" onmouseout="Hui(this)" src="c320_20160923147459793296513.jpg"/>
</div>

</body>

<script type="text/javascript">
function Bian(a)
  {
    a.style.marginTop = "-10px";
    a.style.marginLeft = "-10px";
    a.style.height=" 260px";
    a.style.width= "260px";

  }
function Hui(a)
  {
    a.style.height=" 230px";
    a.style.width= "230px";
    a.style.marginTop = "0px";
    a.style.marginLeft = "0px";
}
</script>

<style type="text/css">

*{ margin:0px auto; padding:0px; font-size:15px; font-family:微软雅黑;}
#a{ width:300px; height:300px; margin-top:150px; overflow:hidden;}
.b{width:300px; height:300px; cursor:pointer; margin-top:0px; margin-left:0px; }
.b:hover{ width:350px; height:350px; margin-top:-25px; margin-left:-25px;  transition: all 1s ease-in-out 0s; }

<style type="text/css">

.t{ width:990px; height:80px; background-color:#F00; font-size:23px;}

</style>

</body>

<script type="text/javascript">

$(document).ready(function(e)
{
  var off=$(".t").offset();  //当前DIV离浏览器边框四边的距离
  var of=off.top-160;  //DIV离顶部的距离-本身DIV高度加顶部DIV高度的总高;(160PX视个人制作的DIV离上边框的距离而定)
  $(window).scroll(function()
    {
      var scr=$(window).scrollTop();  //获取滚动条Y轴距离
        if(scr>of)
          {
            $(".t").css("position","fixed");
            $(".t").css("top","80px");  //根据需要调整
            $(".t").css("background-color","#906");   //根据需要调整
            $(".t").css("left","275px");  //根据需要调整
            $(".t").css("width","800px");  //根据需要调整

          }
        if(scr<of)
          {
            $(".t").css("position","absolute");
            $(".t").css("top","230px");   //根据需要调整
            $(".t").css("background-color","#F00");   //根据需要调整
            $(".t").css("left","180px");  //根据需要调整
