CSS网页技巧：实现超级链接文字上划线和_css

　　链接文字的上划线、下划线、删除线（贯穿线）、闪烁等可以通过css的text-decoration属性来实现。其属性值与效果相对应的关系如下：

text-decoration:
none : 　无装饰
blink : 　闪烁
underline : 　下划线
line-through : 　删除线（贯穿线）
overline : 　上划线

　　学习了此属性的一些用法，我们不难看出，链接文字上划线、下划线同时出现可以通过：text-decoration: underline overline，即可以实现了。或许你有疑问，这两个属性值可以同时了现吗？答案是肯定的，是可以实现的，我们看下面的运行效果：

<p>　　看到效果了吧，虽然我们实现了链接文字上划线、下划线同时出现。但还有很多细节我们并不满意。一、线型单一，只是实线；二、颜色不可更改（默认的线条颜色为链接文字的颜色）；三、距离文字的边距不可控制，感觉离文字太近了。</p> <p>　　我们想到了更好的办法，可以去除text-decoration属性，给链接加上、下边框线，同样可以让上划线、下划线同时出现。我们看下面的运行效果。</p><div><div class="_t33rkthes8f"></div><script type="text/javascript">(window.slotbydup = window.slotbydup ||

<p>　　在默认情况下，块级元素的默认宽度是父级元素的宽度，并且占据一整行的页面空间。所以我们看上面的效果，就出现了一整行都给链接所占据，我们可以作一些调整，设置链接元素为左浮动，并设置左边距为30px。我们来看看效果。</p> <p align=center><textarea style="WIDTH: 490px; HEIGHT: 256px" rows=17
