<!--说明:更改链接，要注意，每个链接的name不能相同，要一次顺延下去，比如name＝a、name＝b.......
<a href="#" class=fade name=a>网页教学网</a>
同时，我们再来研究一下颜色的修改，我们可以通过修改javascript代码。鼠标移出链接的渐变代码：
function fadeout(element) {
fade(255,153,0, 0,0,0, 30, 1, element);
}
其中，255,153,0为起始色；0,0,0为终止色；30为渐变步长；颜色都为RGB。
同理，鼠标移入时的渐变代码：
function fadein(element) {
fade(0,0,0, 255,153,0, 18, 1, element);
}
只要更改这些颜色的RGB，和渐变步长，就能更改效果了！-->
