Extracting inline CSS from HTML Purifier
    voodoofied: Assigning
semantics to elements

Sander Tekelenburg brought to my attention the
poor programming style of
inline CSS in HTML documents.  In an ideal
world, we wouldn't be using inline
CSS at all: everything would be
assigned using semantic class attributes
from an external
stylesheet.

With ExtractStyleBlocks and CSSTidy, this is now possible
(when allowed, users
can specify a style element which gets extracted from
the user-submitted HTML, which
the application can place in the head of
the HTML document).  But there still
is the issue of inline CSS that
refuses to go away.

The basic idea behind this feature is assign every
element a unique identifier,
and then move all of the CSS data to a
style-sheet. This HTML:

<div
style="text-align:center">Big <span
style="color:red;">things</span>!</div>

into

<div
id="hp-12345">Big <span
id="hp-12346">things</span>!</div>

and a
stylesheet that is:

#hp-12345 {text-align:center;}
#hp-12346
{color:red;}

Beyond that, HTML Purifier can magically merge common CSS
values together,
and a whole manner of other heuristic things.  HTML
Purifier should also
make it easy for an admin to re-style the HTML
semantically. Speed is not
an issue. Also, better WYSIWYG editors are
needed.
