求一效果。
CSS3 opacity 是透明属性,

怎样让一个DIV左右两边慢慢透明掉,中间不透明?

相对来说opacity的值就是这样子,不可能要我分成N个DIV设置不同的opacity 值了

0.1 0.3 0.5 0.7 0.9 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0.9 0.7 0.5 0.3 0.1

坛里谁做过这样的效果啊。。也就是说要渐变透明。

变通一下应该就可以了

alpha属性

  alpha是来设置透明度的。先来看一下它的表达格式:

  filter:alpha(opacity=opcity,finishopacity=finishopacity,style=style,startX=startX,tartY=startY,finishX=finishX,finishY=finishY)

  哇,怎么这么长。是啊,不过这些参数都各有其用。
  Opacity代表透明度等级,可选值从0到100,0代表完全透明,100代表完全不透明。 Style参数指定了透明区域的形状特征。其中0代表统一形状;1代表线形;2代表放射状;3代表长方形。
  Finishopacity是一个可选项,用来设置结束时的透明度,从而达到一种渐变效果,它的值也是从0到100。 StartX和StartY代表渐变透明效果的开始坐标,finishX和finishY代表渐变透明效果的结束坐标。 
  从上面讲的我们可以看出,如果不设置透明渐变效果,那么只需设置opacity这一个参数就可以了。说了这么多,我们来看一个实例吧(见下图):
------解决方案--------------------
把div分两半。哈哈
------解决方案--------------------
设置三个div,让两边的div渐变,中间的div保持不变。下面是一个div渐变:

HTML code
 <title>CSS渐变色</title><style type="text/css">.test {width:560px;height:400px;background-color:#FFFFFF;padding:10px 8px 6px;border: 1px solid #000;margin-bottom:10px;FILTER: progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#b8c4cb,endColorStr=#f6f6f8);/*IE6*/background:-moz-linear-gradient(top,#b8c4cb,#f6f6f8);/*非IE6的其它*/background:-webkit-gradient(linear, 0% 0%, 0% 100%, from(#b8c4cb), to(#f6f6f8));/*非IE6的其它*/}</style><div class="test">用CSS生成的渐变色。源码来自:烈火下载 http://www.veryhuo.com/down</div><br><center>如不能显示效果,请按Ctrl+F5刷新本页,更多网页代码:<a href="http://www.veryhuo.com/" target="_blank">http://www.veryhuo.com/</a>

探讨

又是这样子。
怎么都是这样的啊,这个跟楼上那些都是一样的,都是背景颜色渐变而已啊。

是要透明渐变,左右两端透明到看不到东西。不是只是背景变色。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
