我的CSS无法实现我的javascript下拉菜单幻灯片效果

如果你想看我的菜单

因为我知道你会想要我的源代码，下面是CSS：

* {
margin: 0px;
}
#menu-container ul,
#menu-container li,
#menu-container span,
#menu-container a {
  margin: 0;

和JavaScript：

    var menu=function(){
    var t=15,z=50,s=6,a;
    function dd(n){this.n=n; this.h=[]; this.c=[]}
    dd.prototype.init=function(p,c){
        a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'), l=s.length, i=0;
        for(i;i<l;i++){
            var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
            h.onmouseover=new Function(this.n+'.st('+i+',true)');
            h.onmouseout=new Function(this.n+'.st('+i+')');
        }
    }
    dd.prototype.st=function(x,f){
        var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
        clearInterval(c.t); c.style.overflow='hidden';
        if(f){
            p.className+=' '+a;
            if(!c.mh){c.style.display='block'; c.style.height=''; c.mh=c.offsetHeight; c.style.height=0}
            if(c.mh==c.offsetHeight){c.style.overflow='visible'}
            else{c.style.zIndex=z; z++; c.t=setInterval(function(){sl(c,1)},t)}
        }else{p.className=p.className.replace(a,''); c.t=setInterval(function(){sl(c,-1)},t)}
    }
    function sl(c,f){
        var h=c.offsetHeight;
        if((h<=0&&f!=1)||(h>=c.mh&&f==1)){
            if(f==1){c.style.filter=''; c.style.opacity=1; c.style.overflow='visible'}
            clearInterval(c.t); return
        }
        var d=(f==1)?Math.ceil((c.mh-h)/s):Math.ceil(h/s), o=h/c.mh;
        c.style.opacity=o; c.style.filter='alpha(opacity='+(o*100)+')';
        c.style.height=h+(d*f)+'px'
    }
    return{dd:dd}
}();

var菜单=函数（）{
变量t=15，z=50，s=6，a；
函数dd（n）{this.n=n；this.h=[]；this.c=[]}
dd.prototype.init=函数（p，c）{
a=c；var w=document.getElementById（p），s=w.getElementsByTagName（'ul'），l=s.length，i=0；
对于（i；i，菜单[#菜单容器a]中的链接继承了负边距。因此，您的菜单项最终比菜单宽4像素。您可以通过添加到更具体的选择器，将边距重置为0，如下所示：

#menu-container .has-sub ul li a { margin-right: 0 }

当我们说我们需要问题中的代码时，我们不需要你所有的代码。我们需要与问题相关的部分（你应该能够在没有帮助的情况下找出这些部分），你的意思是（演示页）或者？这是子元素居中的问题，而不是
文本对齐：居中
的问题。更改
文本对齐
将其相对于页面居中，并且根本不会更改子元素的位置。实际上，我的意思是，当您将鼠标悬停在某个父元素上时，子元素会向下移动（向下滑动）当他们停下来时，他们会向右移动。我不希望他们向右移动，只要向下滑动即可。@PowerUser你能更清楚一点吗？你是说你想让它向右移动吗
#menu-container .has-sub ul li a { margin-right: 0 }
