css滤镜实现文字描边效果（不支持FF与IE6）

方法1:

<span style="position:absolute;width:150;filter:shadow(color=orange);font-size:45pt;color:yellow">文字</span>

方法2:

<p style="font-size:12px;height:12px;color:white;filter:glow(color=black,strength=1);">Text描边字</p>

方法3:

<style. type="text/css">
body {font:12px "Verdana";filter:alpha(style=1,startY=0,finishY=100,startX=100,finishX=100);background-color:#3366cc;}
span {
      position:absolute;
      padding:4px;
      filter:
          Dropshadow(offx=1,offy=0,color=white)
          Dropshadow(offx=0,offy=1,color=white)
          Dropshadow(offx=0,offy=-1,color=white)
          Dropshadow(offx=-1,offy=0,color=white);
}
#english {
      font-size:14px;}
</style>

<span id="english">This is the prospect of filter - dropshadow.</span><span>中文描边效果</span>

.font {
         font-family: "新宋体";
          font-size: 12px;
          font-style. normal;
          color: #FFFF00;
          padding:1px;
          letter-spacing: 2px;
         
    filter:
         Dropshadow(offx=1,offy=0,color=black)
          Dropshadow(offx=0,offy=1,color=black)
          Dropshadow(offx=0,offy=-1,color=black)
          Dropshadow(offx=-1,offy=0,color=black);
}

方法4:

#text { float:left; color:#C60A12; 
filter:Dropshadow(offx=1,offy=0,color=#ffffff) 
Dropshadow(offx=0,offy=1,color=#ffffff) 
Dropshadow(offx=-1,offy=0,color=#ffffff) 
Dropshadow(offx=0,offy=-1,color=#ffffff);
}

此效果是用css的阴影滤镜来实现，普通的阴影滤镜只会产生一个方向的投影，在这里定义了四个方向的投影，所以产生了描边的效果。

<p style="font-size:12px;height:12px;color:white;filter:glow(color=black,strength=1);">Text描边字</p>
