Hi.
import_css(litehtml::string& text, const litehtml::string& url, litehtml::string& baseurl)
{
text = read_file( someFile );
baseurl = "a/b/c";
}

I set the baseurl "a/b/c" .

but all the function call after import_css, I see baseurl is never used including get_img_size.

Am I miss something ?

the baseurl you set in the import_css is applied to the URLs in this imported CSS only. For example for background images.

Generally the rules for baseurl:

Overwrite the function set_base_url to save base url from <base> tag
Calculate default baseurl based on the url of the opened document. litehtml doesn't know about document url, but document_container implementation should know it.
In the "images function" use baseurl argument if it is not empty. If baseurl is empty, use the calculated default baseurl.
