Question

html 透明度

Answer 1

CSS有优先级

容器也有

和纸被烧了, 纸上的字也会没一个道理

想要实现你说的效果, 就用两张纸, 一张设为100% 放下边
表格40% 浮在上边

<div style="position:absolute;left:100;top:100;width:300px;height:200px;filter:alpha(opacity=40,style=0);z-index:2">
<table border=1>
<tr>
<td width=25%> </td>
<td width=25%> </td>
<td width=25%> </td>
<td width=25%> </td>
</tr>
<tr>
<td width=25%> </td>
<td width=25%> </td>
<td width=25%> </td>
<td width=25%> </td>
</tr>
</table>
</div>
<div style="position:absolute;left:100;top:100;width:300px;height:200px;z-index:1;">
<table cellpadding=1 cellspacing=4>
<tr>
<td width=25%>1</td>
<td width=25%>2</td>
<td width=25%>3</td>
<td width=25%>4</td>
</tr>
<tr>
<td width=25%>5</td>
<td width=25%>6</td>
<td width=25%>7</td>
<td width=25%>8</td>
</tr>
</table>
</div>
