我用dreamweaver8.0设计CSS样式按F12居然没有任何效果

在编辑区右键或者文本菜单里，选css样式-新建样式表，然后弹出新建css规则的对话框，选择你需要的选择器类型，命名，确定。进入css规则定义对话框，设置自己的需要，保存。还可以打开保存好的css样式在上面添加定义规则。

如何用Dreamweaver 8 创建css样式表代码

1、创建css样式，点击窗口\css样式，可以打开css样式编辑窗口，还可以直接在属性面板内创建。

2、点击属性面板的编辑规则，或者是css样式窗口的+号就可以打开新建css规则对话框。

3、选择要创建的css样式的内容。比如要为段落更改样式。

4、在弹出的定义对话框中，选择要更改的各种属性。比如把段落的字体大小改为16px，字体颜色改为红色。

5、点击确定，发现段落中的文字就出现了相应的效果。在head中条件了css样式代码。

请问单击右键出来的菜单是如何悬浮的？就是带有阴影效果的。是CSS做的吗？还是用什么整的？

JS做的，css稍微修改下样式而已！阴影效果可以用图片做，也可以用CSS滤镜做！

如何自定义web界面的右键菜单

在使用电脑的时候经常会用到右击鼠标菜单功能，背景是灰白色的很单调，其实菜单背景是可以更改的哦。下面就看看小编带来的如何美化和自定义鼠标右键菜单背景吧！

答案自然是肯定的！现在就教大家如何给你的电脑右键菜单添加自己喜欢的背景图片。

友情提示：本案例适用全部32位和部分64位的Win7、Win8、Win8.1、Vista和XP系统。

自定义右键菜单背景图片方法如下：

1、在魔方电脑大师的功能大全选项卡中，选择魔方美化大师。

2、在魔方美化大师中，在“系统外观设置”中选择“右键菜单背景”功能。如下图所示，直接点击打开右键菜单背景功能。

3、浏览选择自己喜欢的右键菜单背景图片，然后点击应用到系统按钮（注意：选择的图片大小应与右键菜单相符，否则容易出现背景图重叠或显示不全等问题）！

4、保存到系统中，魔方电脑大师设置的自定义右键背景图片就成功完成了。现在在电脑桌面点击鼠标右键，就可以看到弹出的右键菜单，有了养眼的背景图片。

▲注意事项

▲注意图片大小，不要过大，也不要过小，尤其是宽度。

▲如果想要取消鼠标右键背景图片，可以在魔方电脑大师中，直接选择“恢复到系统默认”按钮。

以上就是今天跟大家分享的“Win7系统如何美化和自定义鼠标右键菜单背景？”的全部内容，更多精彩内容请继续关注！
