background-size - Archive of obsolete content
user:jürgen jeka 2009-08-04 <hr> is there anyway to have the -moz-border-image only apply if -moz-background-size is not supported?
... i'm guessing not, just asking because having both rules in for 3.6 creates a strange effect: -moz-border-image gets inherited by every element on the page user:robertc 2009-08-08 -moz-border-image should not inherit.
...here's a slightly more complex example (screenshot), and the same page without the -moz-border-image image rule (screenshot).
... and anyway, it's more the -moz-border-image that seems to be the problem - that gets inherited even if i add in -moz-border-image: none, to <body> or <html>, and setting the height to 100% is more a matter of covering it up rather than stopping it happening (see further examples a, b and c - b and c look ok, but adding margin or padding reveals that the image applies to both <body> and <html> even though explicitly set to none)...

...for instance, consider the following css: treechildren::-moz-tree-cell(dave) { background-color: lightgreen; } this would set the background color of a cell to green for any cell with the “dave” property.
...g/dc/elements/1.1/title" object="?countrytitle"/> </query> <action> <treechildren> <treeitem uri="?photo"> <treerow properties="?countrytitle"> <treecell src="?photo"/> </treerow> </treeitem> </treechildren> </action> </rule> you might use the following css to change the border around rows listing a particular country: treechildren::-moz-tree-row(netherlands) { border: green 1px solid; } the result of this example is a tree where one row has a green border around it.

Fixing Incorrectly Sized List Item Markers - Archive of obsolete content
the following rule is derived from mozilla's html.css file: *|*:-moz-list-bullet, *|*:-moz-list-number {font-size: 1em;} this rule tells gecko-based browsers to use the computed value of font-size for the marker's parent, which is the list item itself.
... authors who are not concerned with making sure the rule applies across all namespaces can use a slightly more simplified rule: *:-moz-list-bullet, *:-moz-list-number {font-size: 1em;} recommendations if it is important to make list item markers match the font size of the content, use one of the suggested rules.

... the last three lines show three different versions of the linear-gradient() function, which is used to generate a linear gradient in the background of an element: the first one has a -moz- prefix, and shows a slightly older version of the syntax (firefox) the second one has a -webkit- prefix, and shows an even older, proprietary version of the syntax (this is actually from a really old version of the webkit engine).
