Re: libcss selection question

Hi Paul,

When you have a computed style, you can't tell anything about the specificity of the individual properties.

The way to handle this is to provide the `node_presentational_hint` callback [1].  When it is called, you look at the node's attributes and set any appropriate styles as `css_hint`s [2].

2. http://source.netsurf-browser.org/libcss.git/tree/include/libcss/hint.h#n34

Hope this helps,

Michael

Hi all!

How can a user of libcss distinguish between these two situations: a)
property was defined using a default value in CSS and b) property was
undefined in CSS for the node. Those are different because in a latter
case the value of that property should be taken from a node attribute
(in my case of svg styling). As far as I can tell, for a root node, the
property is always initialised using the default value, so when
composing a style I can't distinguish between a and b.

Thanks,

Paul
