我想许多朋友网页制作的朋友和我一样，都遇到过这样的问题："层在某个分辨率下是正常的，可是换了分辨率或调整窗口，层就错位，这种情况最常见的情形就是下拉菜单的制作，鼠标移到一个项目上，子项菜单却从另外的地方弹出来，很烦人吧？怎样才能做到层在不同
我想许多朋友网页制作的朋友和我一样，都遇到过这样的问题："层在某个分辨率下是正常的，可是换了分辨率或调整窗口，层就错位，这种情况最常见的情形就是下拉菜单的制作，鼠标移到一个项目上，子项菜单却从另外的地方弹出来，很烦人吧？怎样才能做到层在不同分辨率下不错位呢？" 现在我们来做一个鼠标移上去就弹出菜单的效果，请看下面的例子： 第一步:新建一个二行一列的表格,为了便于我看一些特殊的元素,我们将表格的边框定义为一;如下(新建表格的快捷键:ctrl+alt+T),
| ? |
| ? |
第二步:将第一行的表格分成5列,(给每列的表格定义颜色定义为红色,并将它们的Brdr也定义为黑色)如下:
| ? | ? | ? | ? | ? | ? |
| ? | |||||
第三步:将第一行表格的每一列输入以下文字(给表格的文字定义一个白颜色,12号字体的CSS教程 href="http://www.blue1000.com/bkhtml/c23/" target=_blank>CSS):
| 图层一下拉菜单 | 图层二下拉菜单 | 图层三下拉菜单 | 图层四下拉菜单 | 图层五下拉菜单 | 图层六下拉菜单 |
| ? | |||||
第四步:插入层,记住要将光标定义在第二表格里再插层,你会看到层的占位符在表格里,如下:
第五步:将层的left和top属性删除如下图:
第六步:将光标定义在layer层里,插入层,如下:

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4.
