[bug]: ignored CSS attributes on html element

That might be a really stupid idea, but it makes sense to me since that's how <html> usually behaves, CSS-wise. For example, on my own sites I use something like html { background: #202020; color: #202020; } body { background: white; width: 6in; margin: 2em auto 2em auto; padding: 1em 4em 1em 4em; border: 2px solid black; } to display the body as a white box against a black background. ~Benjamin

It took me a while to find out, but the reason is rather simple: The <html> is opened before the style is loaded (it's in <head> after all). So at the time we call startElement() for <html>, we don't have the style information. I didn't find anything in the CSS reference how to handle this case, but major browsers seem to allow CSS for the html-element. We could somehow delay the startElement() call for <html> until <head> is parsed completely, but I have to look for a way to make this hack not too ugly...

Yes, you're right. I'm bewildered as to how I could have messed that up. But anyway, dillo ignores the "color" attribute on the html element (as easily seen by changing "text" to "color" in the example I gave and then experimenting with changing between "html" and "body"). So, how to fix this? Regards, Jeremy Henty

Mostly I'm just doing this for educational purposes and I'll just sort of learn as I go along. From what you have told me I can pretty much say that the target system does not have fontconfig on it (I don't ever remember installing it). I will 1. Install it 2. Try fltk without xft.

It's not obvious to me whether this is a > one-liner patch or something more radical is needed. Hm, I've never seen the "text" property in CSS, can you point me to the place where it is documented? Also in http://www.penny-arcade.com/2010/9/10/ I can't find the string "text:" neither in the source nor in the stylesheet - am I missing something? Regards, Johannes

To the best of my knowledge, fltk::HELVETICA, COURIER, TIMES, etc., actually meant Helvetica, Courier, Times, etc., with the old font system, but with xft, they just mean sans, mono, serif, etc. And then in the fontconfig files, sans and friends are set to some specific font (e.g., looking quickly in mine, it seems that fonts.conf makes sans an alias for sans-serif, and then conf.d is full of files that specify that, for the sans-serif family, here are a bunch of specific font families in order of preference...).
