Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Summary
The -moz-user-focus
CSS property is used to indicate whether the element can have the focus.
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.
Initial value | none |
---|---|
Applies to | all elements |
Inherited | no |
Media | interactive |
Computed value | as specified |
Animatable | no |
Canonical order | the unique non-ambiguous order defined by the formal grammar |
Note: This property doesn't work for 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
events.Syntax
/* Keyword values */ -moz-user-focus: normal; -moz-user-focus: ignore; /* Global values */ -moz-user-focus: inherit; -moz-user-focus: initial; -moz-user-focus: unset;

was proposed in early drafts of a predecessor of the CSS3 UI specification but was rejected by the working group.
