Is HTML Purifier Strict or Transitional?
|
|
A little bit of helpful guidance
|
|
|
|
Despite the fact that HTML Purifier professes only to support transitional
|
|
HTML, it rejects a lot of attributes and elements that are actually, indeed,
|
|
valid. You can investigate progress.html to find out precisely what we
|
|
are doing to these *deprecated* attributes.
|
|
|
|
However, users have found that Strict HTML imposes some quite unreasonable
|
|
restrictions on certain things. The start and value attributes in ol and
|
|
li (respectively) perhaps are the most contested. There's is currently no
|
|
widely supported browser method short of JavaScript that can replace these
|
|
two deprecated elements. HTML Purifier does not currently support them, but
|
|
it might behoove us to do so while our output is still transitional.
|
|
|
|
Fortunantely, that's the only real bugger case. The others have near-perfect
|
|
CSS equivalents, and were presentational anyway. However, the other question
|
|
pops up: should we always convert these to the CSS forms when 1. the spec
|
|
allows them anyway and 2. older browsers support them better? After all, the
|
|
whole point about CSS is to seperate styling from content, so inline styling
|
|
doesn't solve that problem.
|
|
|
|
It's an icky question, and we'll have to deal with it as more and more
|
|
transforms get implemented.
