-moz-force-broken-image-icon

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.

The -moz-force-broken-image-icon extended CSS property can be used to force the broken image icon to be shown even when a broken image has an alt attribute.

Syntax

Values

<integer>: A value of 1 means that the broken image icon is shown even if the image has an alt attribute. When the value 0 is used the image will act as usual and only display the alt attribute.

Note: Even if the value is set to 1 the alt attribute will still be displayed, alongside the broken image icon.

Formal definition

Initial value	`0`
Applies to	images
Inherited	no
Computed value	as specified
Animation type	discrete

Formal syntax

<integer>

Examples

}

Result

Screenshot	Live sample

Note: Unless the image has a specified height and width the broken image icon will not be displayed but the alt attribute will also be hidden if -moz-force-broken-image-icon is set to 1.

Notes

This property will only work in Gecko-based browsers.
The use of this property is not recommended. A proper alt attribute should be used instead.
