starting with libcss

[Lukasz Sromek]

Hello everyone,

I want to use libcss in my own project. I tried my best to get it to work, but 
after two days of trying I'm stuck. I figured you guys could give me some 
helpful pointers on how to use your lib.

So, what I achieved so far is this:

        css_error error = css_initialise(aliases_fname, myrealloc, NULL);
        
        lwc_initialise(myrealloc, NULL, 0);
        
        css_stylesheet *sheet;
        
        error = css_stylesheet_create(CSS_LEVEL_21, "UTF-8",
                                                                  "url", NULL, 
true, false,
                                                                  myrealloc, 
NULL, 
                                                                  myresolveurl, 
NULL,
                                                                  &sheet);      
        
        
        char *style_text = "body\
        {\
        background-color:#b0c4de;\
        }";

        uint le = strlen(style_text);
        error = css_stylesheet_append_data(sheet, (const uint8_t*)style_text, 
le);

        error = css_stylesheet_data_done(sheet);
        
        css_finalise(myrealloc, NULL);

style_text is some example css file body. I think it is parsed correctly (I get 
CSS_NEEDDATA as a result of css_stylesheet_append_data), but I have no idea how 
to actually get the parsed data? How to read background-color of the body 
element? Do I have to somehow convert css_stylesheet to css_computed style?

Could you please give me some hints?

Cheers,
Lukasz
