Description Dan Jacobson 2009-01-17 22:32:23 UTC
RSS feeds are so bloated. The CSS stuff is just repeated for every line.
Can't CSS just be declared once somewhere and then single letters used?
A separate file perhaps that such CSS-smart RSS readers could pull in?
And is CSS much value in RSS feeds?
Comment 1 Brion Vibber 2009-01-31 01:32:14 UTC
I wish it could, but <style> tags don't seem to work in many popular readers while inline styles do. Life sucks. :(

And yes, the styles make a *huuuuuuge* difference to legibility of the diff display.
Comment 2 Dan Jacobson 2009-06-01 01:05:31 UTC
Am I mistaken, or is it a total waste to write class="..." in an RSS environment, at least the current way we see?
Comment 3 Dan Jacobson 2009-06-02 07:52:55 UTC
Here's what I found out so far running
>$ firefox
which contains
><?xml-stylesheet type="text/css" href=""?>
>...class='diff-marker' etc.
However diff-marker etc. is not mentioned in feed.css, but elsewhere,
and Firefox in fact here doesn't read feed.css afterall, nor any *.css.

So I don't see how feed.css is to achieve the goal at its top,
>Make RSS and Atom feeds at least semi-legible to folk who accidentally load them in a browser...
>* Mozilla is fine.
Note that the headers sent say Content-Type: application/xml ...

Special:NewPages&feed=rss also attempts to invoke feed.css.
Comment 4 Brion Vibber 2009-09-23 21:58:26 UTC
feed.css is for browsers that will apply CSS to XML, but *don't* recognize RSS/Atom feeds specifically (for instance, very old versions of Firefox).

Many/most modern browsers know RSS and/or Atom feed formats natively, and never see that XML stylesheet reference. They parse out the feed and build their own user interface for showing you the feed items.

They also tend to completely ignore any <style> blocks in those individual feed items, which is why we have to embed the styles to get legible output; we can't use a <style> block or <link rel="stylesheet"> to style them because it just won't work... This was added in r12913 for bug 1284.

That was 3 years ago, so it wouldn't hurt to do an environmental scan of current feed readers to check for improved <style> support, but unless that's been fixed I'm not sure how much we can do. We could at least reduce the bloat by removing the white background / black foreground or something.
Comment 5 Dan Jacobson 2011-12-02 00:13:04 UTC
How about XML CDATA enclosures to clean up all those entities?
In Xquery we use e.g., declare option output:cdata-section-elements "description";
to get e.g., <description><![CDATA[<ul><li>中國廣播公司客家頻道台北台</li><li>台北縣板橋市民族路130巷67號</li><li>丙</li></ul>]]></description>
instead of &lt;ul&gt;&lt;li&gt;中國廣播公司鄉親網台北台...
Wonder if it works in RSS.
And now it's 5 years ago...
Comment 6 Bartosz Dziewoński 2014-08-22 18:09:57 UTC
Closing again per Brion, nothing has changed in the five years and it seems it won't. This is the only way to provide styles with feeds.
Comment 7 Bartosz Dziewoński 2014-08-22 18:11:16 UTC
(Perhaps "CANTFIX" would be a better resolution than "WONTFIX", but we don't have one. We might use "INVALID", but this is a valid report to me, the issue just happens to be unfixable.)
