Thank you.
With nsComputedDOMStyle*, I can call
nsCOMPtr<nsIDOMCSSValue> cssValue;
nsresult rv = computedDOMStyle-
>GetBackgroundColor(getter_AddRefs(cssValue));
which return the css value in nsIDOMCSSValue.
But nsIDOMCSSStyleDeclaration*, I can only get the background color in
a nsAutoString.
like this:
nsAutoString propertyValue;
computedStyle->GetPropertyValue(propertyName,
propertyValue);
Thank you.
