-moz-force-broken-image-icon - CSS: Cascading Style Sheets 编辑

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

Result
