Can you use the browser specific prefix in front of all standard tags?
e.g.
#div{
padding:20px;
-moz-padding-bottom:10px;
}
is the above valid CSS for ensuring Firefox has a different bottom padding to all other browsers?
No, it's not a prefix for targetting a browser, it's a prefix that is used for specific non-standard properties like -moz-opacity
or -moz-padding-start
. It's not available for the standard properties.
