非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

-moz-user-focus CSS property is used to indicate whether an element can have the focus.

/* Keyword values */
-moz-user-focus: normal;
-moz-user-focus: ignore;
/* Global values */
-moz-user-focus: inherit;
-moz-user-focus: initial;
-moz-user-focus: unset;
					

By setting its value to ignore , you can disable focusing the element, which means that the user will not be able to activate the element. The element will be skipped in the tab sequence.

初始值	none
适用于	所有元素
继承	no
计算值	如指定
动画类型	discrete

注意： This property doesn't work for XUL <xul:textbox> elements, because the textbox itself never takes focus. Instead, XBL creates an anonymous HTML <input> element inside the textbox , and that element is what receives focus. You can stop the textbox from taking keyboard focus by setting its tab index to -1 , and from taking mouse focus by preventing the default action of mousedown 事件。

Not part of any standard. A similar property, user-focus , was proposed in early drafts of a predecessor of the CSS3 UI specification , but was rejected by the working group.
