what would it take to allow media queries through HTMLPurifier + CSStidy?
In other words, I am using these libraries:
require_once 'inc_php_classes/htmlpurifier-4_4_0/library/HTMLPurifier.auto.php';
require_once 'inc_php_classes/csstidy-1_3/class.csstidy.php';
…to sanitize admin-user input before I save it to database.. for populating an external style sheet … and so it happens that any input media queries are getting munged.. e.g. this:
@media only screen and (min-width: 600px) and (max-width: 939px) {
becomes
@media only screen and min-width 600px and max-width 939px {
..which breaks the media query, at least in Chrome 18/Mac.
The form/input is used for creating custom style sheets for trusted admin users.. and they need media queries.. but even though they are trusted, I do not want to just drop use of CSStidy.. because of the off chance an admin goes AWOL, not to mention I want to clean their newbie CSS errors.
Not sure, it’s definitely not supported by vanilla HTML Purifier. It is reasonably plausible that CSSTidy does parse media selectors properly, so it’s just a matter of teaching HTML Purifire not to strip them out.
