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。

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：

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。
