- 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.
