== CSS and syndication (another CSS limitation)
In an [[earlier entry ../solaris/PatchExitCodes]] on Solaris patch
exit codes I mentioned that its formatting might not look very nice in
syndication feeds. And I was right; it did not look very good.
It didn't look good because it was styled with CSS, and you can't really
put CSS in syndication feeds. CSS goes into the HTML
element,
but that only appears in HTML pages; syndication feeds and entries are
divorced from that sort of context. This is more or less implicit in
RSS ([[like a lot of things ../tech/AtomVsRSS]]), but is explicit
in Atom 1.0; both HTML and XHTML entries must be markup that is valid
inside a .
(Technically you can wedge a certain amount into _style="..."_
attributes on elements, but you can't get everything. And it
significantly bulks things up. And apparently a number of feed readers
strip _style_ attributes because they can contain various dangerous
things, like JavaScript.)
You can substitute deprecated HTML features for some things, but not
always. For example, in the [[earlier entry]], I had a 'horizontal'
table, one where the important thing was the relationships between the
columns in the same row; in CSS it has light thin horizontal lines
after each row. In syndication feeds I eventually decided that the best
approximation (or at least the least annoying to me) was for there to be
no borders at all.
Because of this limitation and my desire for my entries to be decently
readable in feed readers, I've generally held back from making much use
of CSS in WanderingThoughts. Sometimes it's very tempting, though; for
example, I really like the CSS appearance of 'horizontal' tables. (I'm
willing to live with them [[not looking good in lynx CSSLimitationsI]],
for fuzzy reasons.)
Because WanderingThoughts generates HTML from [[higher level markup
WhySimpleMarkup]], I'm actually better off than many people; I could
in theory render entirely different HTML for the Atom feeds (inlining
styles and all that) than for regular page views. (The Atom feed already
changes some stuff, for example to make all links into absolute URLs.)
(Credit where credit is due department: I got the idea for
the 'horizontal' table style from how CJ Silverio's [[Snippy
http://snippy.ceejbot.com/wiki/show/snippy]] styles tables.)
