Dreamweaver定制网页过渡功能: 
首先用Dreamweaver打开页面，然后单击菜单中的Insert\Head\Meta（插入/文件头标签/Meta）. 

　　在对话框中的Attribute选项的下拉列表中选HTTP-equivalent选项，在Value：中键入Page-Enter，表示进入网页时有网页过渡效果。在Content:中键入Revealtrans(Duration=6,Transition=2),Duration=6表示网页过渡效果的延续时间为6秒，Transition表示过渡效果方式，值为2时表示圆形收缩。 
输入完后单击确定，存盘。这样当我们点击一个超链接进入这个页面时就可以看到效果了。另外还有二十多种效供你选择，只要将Transition的值改为相应的效果的代号即可，具体效果和设置如下表所示
上一个：多图幻灯Wipe擦洗效果
下一个：在table中插入多行，能使用与insertAdjacentHTML相似的功能吗？
