If an individual element in the base list has the 'important' attribute set to TRUE, then it does *not* get overwritten.
css_merge_core(base, new)
| base | the original list |
|---|---|
| new | the new list from which to take values and put into base |
updated version of base list
Some properties are accumulative, rather than replacement-based. E.g.
SVGs transform attribute combines parent + child transform
matrices. For now, any accumulative properties are concatenated into
a vector of character stirngs to be dealt with by the user after
parsing.
Otherwise, this function behaves very much like utils::modifyList()
